*The tutorial shows how to build an amortization schedule in Excel to detail periodic payments on an amortizing loan or mortgage.*

An **amortizing loan** is just a fancy way to define a loan that is paid back in installments throughout the entire term of the loan.

Basically, all loans are amortizing in one way or another. For example, a fully amortizing loan for 24 months will have 24 equal monthly payments. Each payment applies some amount towards principal and some towards interest. To detail each payment on a loan, you can build a loan amortization schedule.

An **amortization schedule** is a table that lists periodic payments on a loan or mortgage over time, breaks down each payment into principal and interest, and shows the remaining balance after each payment.

## How to create a loan amortization schedule in Excel

To build a loan or mortgage amortization schedule in Excel, we will need to use the following functions:

- PMT function - calculates the
**total amount**of a periodic payment. This amount stays constant for the entire duration of the loan. - PPMT function - gets the
**principal**part of each payment that goes toward the loan principal, i.e. the amount you borrowed. This amount increases for subsequent payments. - IPMT function - finds the
**interest**part of each payment that goes toward interest. This amount decreases with each payment.

Now, let's go through the process step-by-step.

### 1. Set up the amortization table

For starters, define the input cells where you will enter the known components of a loan:

- C2 - annual interest rate
- C3 - loan term in years
- C4 - number of payments per year
- C5 - loan amount

The next thing you do is to create an amortization table with the labels (*Period*, *Payment*, *Interest*, *Principal*, *Balance*) in A7:E7. In the *Period* column, enter a series of numbers equal to the total number of payments (1- 24 in this example):

With all the known components in place, let's get to the most interesting part - loan amortization formulas.

### 2. Calculate total payment amount (PMT formula)

The payment amount is calculated with the PMT(rate, nper, pv, [fv], [type]) function.

To handle different payment frequencies correctly (such as weekly, monthly, quarterly, etc.), you should be consistent with the values supplied for the *rate* and *nper* arguments:

**Rate**- divide the annual interest rate by the number of payment periods per year ($C$2/$C$4).**Nper**- multiply the number of years by the number of payment periods per year ($C$3*$C$4).- For the
**pv**argument, enter the loan amount ($C$5). - The
**fv**and**type**arguments can be omitted since their default values work just fine for us (balance after the last payment is supposed to be 0; payments are made at the end of each period).

Putting the above arguments together, we get this formula:

`=PMT($C$2/$C$4, $C$3*$C$4, $C$5)`

Please pay attention, that we use absolute cell references because this formula should copy to the below cells without any changes.

Enter the PMT formula in B8, drag it down the column, and you will see a constant payment amount for all the periods:

### 3. Calculate interest (IPMT formula)

To find the interest part of each periodic payment, use the IPMT(rate, per, nper, pv, [fv], [type]) function:

`=IPMT($C$2/$C$4, A8, $C$3*$C$4, $C$5)`

All the arguments are the same as in the PMT formula, except the **per** argument that specifies the payment period. This argument is supplied as a relative cell reference (A8) because it is supposed to change based on the relative position of a row to which the formula is copied.

This formula goes to C8, and then you copy it down to as many cells as needed:

### 4. Find principal (PPMT formula)

To calculate the principal part of each periodic payment, use this PPMT formula:

`=PPMT($C$2/$C$4, A8, $C$3*$C$4, $C$5)`

The syntax and arguments are exactly the same as in the IPMT formula discussed above:

This formula goes to column D, beginning in D8:

Tip. To check whether your calculations are correct at this point, add up the numbers in the *Principal* and *Interest* columns. The sum should be equal to the value in the *Payment* column in the same row.

### 5. Get the remaining balance

To calculate the remaining balance for each period, we'll be using two different formulas.

To find the balance after the first payment in E8, add up the loan amount (C5) and the principal of the first period (D8):

`=C5+D8`

Because the loan amount is a positive number and principal is a negative number, the latter is actually subtracted from the former.

For the second and all succeeding periods, add up the previous balance and this period's principal:

`=E8+D9`

The above formula goes to E9, and then you copy it down the column. Due to the use of relative cell references, the formula adjusts correctly for each row.

That's it! Our monthly loan amortization schedule is done:

### Tip: Return payments as positive numbers

Because a loan is paid out of your bank account, Excel functions return the payment, interest and principal as **negative numbers**. By default, these values are highlighted in red and enclosed in parentheses as you can see in the image above.

If you prefer to have all the results as **positive** numbers, put a minus sign before the PMT, IPMT and PPMT functions.

For the *Balance* formulas, use subtraction instead of addition like shown in the screenshot below:

## Amortization schedule for a variable number of periods

In the above example, we built a loan amortization schedule for the predefined number of payment periods. This quick one-time solution works well for a specific loan or mortgage.

If you are looking to create a reusable amortization schedule with a variable number of periods, you will have to take a more comprehensive approach described below.

### 1. Input the maximum number of periods

In the *Period* column, insert the maximum number of payments you are going to allow for any loan, say, from 1 to 360. You can leverage Excel's AutoFill feature to enter a series of numbers faster.

### 2. Use IF statements in amortization formulas

Because you now have many excessive period numbers, you have to somehow limit the calculations to the actual number of payments for a particular loan. This can be done by wrapping each formula into an IF statement. The logical test of the IF statement checks if the period number in the current row is less than or equal to the total number of payments. If the logical test is TRUE, the corresponding function is calculated; if FALSE, an empty string is returned.

Assuming *Period 1* is in row 8, enter the following formulas in the corresponding cells, and then copy them across the entire table.

**Payment** (B8):

`=IF(A8<=$C$3*$C$4, PMT($C$2/$C$4, $C$3*$C$4, $C$5), "")`

**Interest** (C8):

`=IF(A8<=$C$3*$C$4, IPMT($C$2/$C$4, A8, $C$3*$C$4, $C$5), "")`

**Principal** (D8):

`=IF(A8<=$C$3*$C$4,PPMT($C$2/$C$4, A8, $C$3*$C$4, $C$5), "")`

**Balance**:

For *Period 1* (E8), the formula is the same as in the previous example:

`=C5+D8`

For *Period 2* (E9) and all subsequent periods, the formula takes this shape:

`=IF(A9<=$C$3*$C$4, E8+D9, "")`

As the result, you have a correctly calculated amortization schedule and a bunch of empty rows with the period numbers after the loan is paid off.

### 3. Hide extra periods numbers

If you can live with a bunch of superfluous period numbers displayed after the last payment, you can consider the work done and skip this step. If you strive for perfection, then hide all unused periods by making a conditional formatting rule that sets the **font color to white** for any rows after the last payment is made.

For this, select all the **data rows** if your amortization table (A8:E367 in our case) and click *Home* tab > *Conditional formatting* > *New Rule…* > *Use a formula to determine which cells to format*.

In the corresponding box, enter the below formula that checks if the period number in column A is greater than the total number of payments:

`=$A8>$C$3*$C$4`

Important note! For the conditional formatting formula to work correctly, be sure to use absolute cell references for the *Loan term* and *Payments per year* cells that you multiply ($C$3*$C$4). The product is compared with the *Period* 1 cell, for which you use a mixed cell reference - absolute column and relative row ($A8).

After that, click the *Format…* button and pick the white font color. Done!

### 4. Make a loan summary

To view the summary information about your loan at a glance, add a couple more formulas at the top of your amortization schedule.

**Total payments** (F2):

`=-SUM(B8:B367)`

**Total interest** (F3):

`=-SUM(C8:C367)`

If you have payments as positive numbers, remove the minus sign from the above formulas.

That's it! Our loan amortization schedule is completed and good to go!

## How to make a loan amortization schedule with extra payments in Excel

The amortization schedules discussed in the previous examples are easy to create and follow (hopefully :). However, they leave out a useful feature that many loan payers are interested in - additional payments to pay off a loan faster. In this example, we will look at how to create a loan amortization schedule with extra payments.

### 1. Define input cells

As usual, begin with setting up the input cells. In this case, let's name these cells like written below to make our formulas easier to read:

*InterestRate*- C2 (annual interest rate)*LoanTerm*- C3 (loan term in years)*PaymentsPerYear*- C4 (number of payments per year)*LoanAmount*- C5 (total loan amount)*ExtraPayment*- C6 (extra payment per period)

### 2. Calculate a scheduled payment

Apart from the input cells, one more predefined cell is required for our further calculations - the **scheduled payment amount**, i.e. the amount to be paid on a loan if no extra payments are made. This amount is calculated with the following formula:

`=IFERROR(-PMT(InterestRate/PaymentsPerYear, LoanTerm*PaymentsPerYear, LoanAmount), "")`

Please pay attention that we put a minus sign before the PMT function to have the result as a positive number. To prevent errors in case some of the input cells are empty, we enclose the PMT formula within the IFERROR function.

Enter this formula in some cell (G2 in our case) and name that cell *ScheduledPayment*.

### 3. Set up the amortization table

Create a loan amortization table with the headers shown in the screenshot below. In the *Period* column enter a series of numbers beginning with zero (you can hide the *Period 0* row later if needed).

If you aim to create a reusable amortization schedule, enter the maximum possible number of payment periods (0 to 360 in this example).

For *Period 0* (row 9 in our case), pull the **Balance** value, which is equal to the original loan amount. All other cells in this row will remain empty:

Formula in G9:

`=LoanAmount`

### 4. Build formulas for amortization schedule with extra payments

This is a key part of our work. Because Excel's built-in functions do not provide for additional payments, we will have to do all the math on our own.

Note. In this example, *Period 0* is in row 9 and *Period 1* is in row 10. If your amortization table begins in a different row, please be sure to adjust the cell references accordingly.

Enter the following formulas in row 10 (*Period 1*), and then copy them down for all of the remaining periods.

**Scheduled Payment** (B10):

If the *ScheduledPayment* amount (named cell G2) is less than or equal to the remaining balance (G9), use the scheduled payment. Otherwise, add the remaining balance and the interest for the previous month.

`=IFERROR(IF(ScheduledPayment<=G9, ScheduledPayment, G9+G9*InterestRate/PaymentsPerYear), "")`

As an extra precaution, we wrap this and all subsequent formulas in the IFERROR function. This will prevent a bunch of various errors if some of the input cells are empty or contain invalid values.

**Extra Payment** (C10):

Use an IF formula with the following logic:

If the *ExtraPayment* amount (named cell C6) is less than the difference between the remaining balance and this period's principal (G9-E10), return *ExtraPayment*; otherwise use the difference.

`=IFERROR(IF(ExtraPayment<G9-E10, ExtraPayment, G9-E10), "")`

Tip. If you have **variable additional payments**, just type the individual amounts directly in the *Extra Payment* column.

**Total Payment** (D10)

Simply, add the scheduled payment (B10) and the extra payment (C10) for the current period:

`=IFERROR(B10+C10, "")`

**Principal** (E10)

If the schedule payment for a given period is greater than zero, return a smaller of the two values: scheduled payment minus interest (B10-F10) or the remaining balance (G9); otherwise return zero.

`=IFERROR(IF(B10>0, MIN(B10-F10, G9), 0), "")`

Please note that the principal only includes the part of the **scheduled payment** (not the extra payment!) that goes toward the loan principal.

**Interest **(F10)

If the schedule payment for a given period is greater than zero, divide the annual interest rate (named cell C2) by the number of payments per year (named cell C4) and multiply the result by the balance remaining after the previous period; otherwise, return 0.

`=IFERROR(IF(B10>0, InterestRate/PaymentsPerYear*G9, 0), "")`

**Balance** (G10)

If the remaining balance (G9) is greater than zero, subtract the principal portion of the payment (E10) and the extra payment (C10) from the balance remaining after the previous period (G9); otherwise return 0.

`=IFERROR(IF(G9 >0, G9-E10-C10, 0), "")`

Note. Because some of the formulas cross reference each other (not circular reference!), they may display wrong results in the process. So, please do not start troubleshooting until you enter the very last formula in your amortization table.

If all done correctly, your loan amortization schedule at this point should look something like this:

### 5. Hide extra periods

Set up a conditional formatting rule to hide the values in unused periods as explained in this tip. The difference is that this time we apply the **white font color** to the rows in which *Total Payment* (column D) and *Balance* (column G) are equal to zero or empty:

`=AND(OR($D9=0, $D9=""), OR($G9=0, $G9=""))`

Voilà, all rows with zero values are hidden from view:

### 6. Make a loan summary

As a finishing touch of perfection, you can output the most important information about a loan by using these formulas:

**Scheduled number of payments:**

Multiply the number of years by the number of payments per year:

`=LoanTerm*PaymentsPerYear`

**Actual number of payments:**

Count cells in the *Total Payment* column that are greater than zero, beginning with Period 1:

`=COUNTIF(D10:D369,">"&0)`

**Total extra payments:**

Add up cells in the *Extra Payment* column, beginning with Period 1:

`=SUM(C10:C369)`

**Total interest:**

Add up cells in the *Interest* column, beginning with Period 1:

`=SUM(F10:F369)`

Optionally, hide the *Period 0* row, and your loan amortization schedule with additional payments is done! The screenshot below shows the final result:

## Amortization schedule Excel template

To make a top-notch loan amortization schedule in no time, make use of Excel's inbuilt templates. Just go to *File* > *New*, type "*amortization schedule*" in the search box and pick the template you like, for example, this one with extra payments:

Then save the newly created workbook as an Excel template and reuse whenever you want.

That's how you create a loan or mortgage amortization schedule in Excel. I thank you for reading and hope to see you on our blog next week!

Or maybe you have it correct, but it is just very hard to see because of the impossibly short amortization period? I will try this with a 30-year am and it will be clearer to see.

Just one thing that may help some people who are saying there that they cannot get this to work. I think it is the backwards phrasing. Instead of saying "put $25,000 in cell b4," it is easier for the human brain to process so many steps if they are all put in the order that the eye/brain move:

1. Go to cell B4.

2. Enter the original loan balance of $25,000.

I have found this backward phrasing so frustrating that I am going to exit this page and write my own formulas.

I'm confused. The point of amortization is for the lender to front load his receipt of interest. To do this, the bulk of the early payments to go interest, and a tiny part goes toward principal paydown. This ratio reverses as you move through the months/years of payments.

Doesn't your chart show the opposite? (With the bulk of the early payments going toward principal, which is wrong in USA lending.)

Hi. Trying to modify this table to account for additional monthly charges.

which adds to the loan amount instead of extra payments which reduces the loan amount. Do I simply add a minus sign to the extra payment figures or is there another way I can do this? Considering the interest rate is on the amount borrowed and not the total repayment amount. Thanks.

thnks!

Thank you Svetlana Cheusheva! I followed your examples and they worked perfectly. I did have to look up the defined naming, but other than that, you provided everything.

I followed your tutorial using the same example data and got the exact same results (and learnt a lot along the way, thanks!), which is great. However, I also followed a different tutorial (not from ablebits), which used PPMT, IPMT and included extra payments. The results were similar, but the Total Interest ended up being $166.77 higher than in your example.

The logic used in both tutorials seems the same, ie balance-principal-extra payment, and both assume the extra payment go towards the Principle Balance, but the results are different. I'm guessing it's as you said in this post, "Because Excel's built-in functions do not provide for additional payments, we will have to do all the math on our own", but I'd love to understand why the difference.

Your formula to calculate the balance is: =IFERROR(IF(G9 >0, G9-E10-C10, 0), "")

The other tutorial's formula is: =I10-K10-N10 (which is essentially the same as 'G9-E10-C10' ). So, it seems the difference is in how the input cells are calculated:

I10 = Starting Balance

K10 = Principal PMT Portion (cell formula is -PPMT(InterestRate/12, Period, Term, Principle (absolute reference)))

N10 = Extra Payment

Can you shed any light?

I need assistance in setting up a loan amortization schedule with the following columns:

1. Due date ( due dates should be one month apart starting from the loan issue date)

2. Payment date

3. Payment amount

4. Accrued interest

5. Principal payment

6. Interest Payment

7. Principal balance

8. Interest balance

The rules for the schedule are as follows:

1. The loans are amortized loans; interest is charged on the reducing balance of the principal

2. If a client misses payment on a due date, interest is charged on principal plus total interest accrued as at the last due date.

3. Repayment is first setoff against any interest accrued and the remainder, if any, if used to reduce the principal outstanding.

Thank you.

Your request goes beyond the advice we provide on this blog. This is a complex solution that cannot be found with a single formula. If you have a specific question about the operation of a function or formula, I will try to answer it.

I'm trying to create the schedule with extra payments but can't get past steps 1 and 2...

Are we supposed to name the input cells as "InterestRate - C2 (annual interest rate)" or "annual interest rate" in cell A2?

Also, the instruction for step 1 looks like were supposed to type "InterestRate" as a hyperlink somehow in cell D2 but in the example for step 2, that cell is blank.

I have tried the names each way and can't get the balance or schedule payment fields to calculate.

Nevermind... I didn't know about the "Name Box". Now that I know about that, this instruction just got much easier!

Thank you!

QUESTION. NOT THAT I AM EXCEL EXPERT, I BUILT TABLE ABOVE. DON'T UNDERSTAND HOW INTEREST IS CALCULATED WHEN THE BALANCE IS NOT IN THE FORMULA. I TESTED FORMULA BY ADDING 200.00 TO PAYMENT AMOUNT, BALANCE WAS REDUCED, BUT INTEREST IN ALL COLUMNS REMAINED UNCHANGED.

Hi Team, these are really nice schedules. However, could you please assist with a schedule that has additional borrowings plus the initial loan.

Initial loan in year 1 and subsequent loans in years 3,4 and 5 respectively.

Thank you Team

Hello!

I am looking for a sheet like this but can hold 30+ vehicles on one sheet and goes vertical with the information and not horizontal. Do you know of anything out there like that?
