# Loan Amortization Schedule Google Sheets Template + Guide

Fact Checked By Jim Markus

See the interest and principal for each payment with this loan amortization schedule. Below, I’ll explain how to create one from scratch. I also include a free loan amortization schedule template for Google Sheets. You can use it to maintain a budget, track expenditures, schedule activities or pay off loans on time.

## What is a Google Sheets Loan Amortization Schedule?

An amortized loan is a type of loan that involves periodic payments scheduled over a given period. Payments are applied to both the loanâ€™s principal amount and to the interest.

The process consists of first paying off the relevant interest for the period so that the rest of the payment can be put towards reducing the principal amount.

## What Does a Loan Amortization Schedule Google Sheets Spreadsheet Consist Of?

A loan amortization spreadsheet consists of a schedule of periodic loan payments. The schedule shows the principal amount and amount of interest for each payment from the start till the loan is paid off at the end of the term.

The repayment process consists of paying the same amount in each periodic payment. However, during the start of the process, most of the amount pays off the interest, while towards the end, most of the amount covers the principal amount.

This, in turn, makes the repayment process comfortable for the borrower and reduces the overall cost of the loan.

The last line of the table shows the borrowerâ€™s total interest and principal payments for the entire term. Note that you can use this for any type of loan, including student loans or mortgages.

## How to Create a Loan Amortization Schedule in Google Sheets

So now that we know the basics, letâ€™s get down to actually building the spreadsheet.

We will first start by creating a basic skeleton of the sheet, in which we will enter the basic timeline, the starting date, the interest rate of the loan, and the total amount to be paid off.

After this, we will create the table and fill in the first two rows with the appropriate formulas. In the end, all we need to do is simply drag down the formulas to fill in the rest of the schedule. The last row should display an amount of 0.0 in the loan balance column.

The top part of the worksheet (rows 1 and 2) consists of all the values that are going to remain constant throughout the loan period:

• The Principal amount for the loan, or the total loan amount that needs to be paid off.
• The interest rateÂ that is to be applied on the loan.
• The term (in years) or the period within which the loan is to be repaid.
• The starting dateÂ from when the loan repayment schedule begins.

Let us assume we have a home loan of \$100,000 to be repaid in 10 years, with an interest rate of 5%, starting from 06/29/2021. So let us fill these values in the table:

Once this is done, you can start filling in the lower part of the worksheet.

## Filling in the Main Amortization Table

Now it is time to fill in the main part of the worksheet. Here are the columns you will need to fill:

### Period

The Period column will consist of the serial number of the payment period. So for the first installment, the period will be 1, for the second installment it will be 2, etc.

Enter 0 in the first row of this column and 1 in the second row.

### Date

The Date column consists of dates when each payment is due. In the first row, the date is the same as the starting date (of cell E2). After this, each date will be one month apart (since you are paying off each installment every month).

So in the first row of this column, enter the formula: =E2

In the second row, enter the formula:

`=DATE(YEAR(B7),MONTH(B7)+1,Day(B7))`

This will return a date exactly one month after the date in cell B7.

### Monthly Payment

Next, we need to calculate the monthly payment for each row. To calculate the monthly payment we can use Google Sheetsâ€™ PMT function.

#### The PMT Function

The PMT function calculates the periodic payment for an annuity investment, where the amount and interest rate are constant for each periodic payment.

The syntax for the PMT function is as follows:

`PMT(rate, number_of_periods,Â present_value, [future_value, end_or_beginning])`

Here,

• rate is the rate of interest for the payment period.
• number_of_periodsÂ is the number of payment installments.
• present_valueÂ is nothing but the principal amount.
• future_valueÂ is optional. It is the future value remaining after the final payment has been made.
• end_or_beginningÂ is also optional. It specifies if the payments are due at the end (0) or start (0) of each period. By default this value is 0.

In our example, here are the values that we will need to plug in:

• rate:Â The interest rate in cell B2 is for a whole year, but this parameter calls for the monthly interest rate. So this value will be B2/12.
• number_of_periods:Â This parameter will contain the number of periods in months. Since cell E1 contains the period in years, this value will be E1*12
• present_value:Â The principal amount is in cell B1, so that is what we will enter in this parameter.

Since you donâ€™t need to pay the monthly fee on the starting date, this value can be 0.00 for the first row.

In the second row, you can enter the following formula:

`=PMT(\$B\$2/12, \$E\$1*12,\$B\$1)`

We locked all the cell references with \$ symbols, because we donâ€™t want these references to get updated when we copy the formula down to the rest of the rows.

Remember, the monthly payment is going to be the same amount for each period. So all the rows of this column will basically have the same value.

Note: The value returned is negative because this is an outgoing payment. In financial terms, outgoing payments are always represented as a negative number while incoming payments are represented as a positive number.

### Interest Payment

This column will show the interest to be paid in each installment. To calculate the monthly interest payment, we can use the Google Sheetsâ€™ IPMT function.

#### The IPMT Function

The IPMT function calculates the interest payment for an annuity investment, where the amount and interest rate are constant for each periodic payment.

The syntax for the IPMT function is as follows:

`IPMT(rate, period, number_of_periods, present_value, [future_value, end_or_beginning])`

Here,

• rate is the rate of interest for the payment period.
• period is the amortization period serial number.
• number_of_periodsÂ is the number of payment installments.
• present_valueÂ is the principal amount.
• future_valueÂ is optional. It is the future value remaining after the final payment has been made.
• end_or_beginningÂ is also optional. It specifies if the payments are due at the end (0) or start (0) of each period. By default this value is 0.

In our example, here are the values that we will need to plug in:

• rate:Â The interest rate in cell B2 is for a whole year, but this parameter calls for the monthly interest rate. So this value will be B2/12.
• period:Â This will contain the serial number of the payment period. This value is contained in column A for each corresponding row, so for the second row, the value will be A8.
• number_of_periods:Â This parameter will contain the number of periods in months. Since cell E1 contains the period in years, this value will be E1*12
• present_value:Â The principal amount is in cell B1, so that is what we will enter in this parameter.

Since you donâ€™t need to pay the interest amount on the starting date, this value can be 0.00 for the first row.

In the second row, you can enter the following formula:

`=IPMT(\$B\$2/12, A8, \$E\$1*12,\$B\$1)`

We locked all the cell references with \$ symbols, because we donâ€™t want these references to get updated when we copy the formula down to the rest of the rows.

The only reference we did not lock is the second one (representing the period), because this value needs to change with every row.

### Principal Payment

This column consists of the principal amount that needs to be paid for the current installment. This value can be obtained by subtracting the current interest payment from the current monthly paymentÂ value. So, for the second row, enter the formula:

`=C8-D8`

The first row will again carry the value 0.00.

### Loan Balance

This column will hold the amount of loan yet to be repaid. This value can be obtained by subtracting the current principal paymentÂ from the previous loan balance.

In the first row, since no money has been paid yet, this value will contain the entire principal amountÂ (or a reference to cellÂ B1).

In the second row, the value will be:

`=E8+F7`

Since the Principal paymentÂ amount is a negative number, we used the â€˜+â€™ sign, instead of â€˜-â€˜.

Once you have the first two rows filled in, all thatâ€™s left to do is copy down the values to the rest of the rows. Do this by selecting the entire row and pulling down the fill handle to the number of rows needed.

This means, if you have to repay the loan in 10 years, you should have 10*12=120 rows.

Your last row should have a loan balance of 0.0.

## Summarizing the Information in the Last Row in The Â Loan Amortization Calculator Google Sheets Template

The last row of the amortization table should show the borrowerâ€™s total interest and principal payments for the entire term.

The total interest can be calculated by summing up the values in column D . So in cell C129 enter the formula:

`=SUM(D7:D)`

The principal payments for the entire term is calculated by summing up the values in column E. So in cell C130 enter the formula:

`=SUM(E7:E)`

Your loan amortization schedule Google Sheets spreadsheet is now ready, and since the formulas have been interlinked with the appropriate cell references, any changes in the principal amount, interest rate, term, or starting date will get automatically updated everywhere.
