Are you struggling with calculating the monthly payment, principal, or interest of a loan in Excel? Whether you’re planning a new loan, refinancing, or just curious about how much you owe, the process of figuring out these amounts can often feel like a daunting task, especially when there are multiple variables involved like loan amount, interest rate, and loan tenure.
But don’t worry there’s a feature for Loan payments in Excel has powerful functions to help you make these calculations with ease. Enter PMT, PPMT, and IPMT: three crucial financial functions that can help you calculate monthly payments, principal payments, and interest payments for loans. Let’s take a deep dive into how these functions work, when and why to use them, and how to implement them step-by-step with a practical dataset.
Overview of the Functions
- PMT Function
- The PMT function is used to calculate the monthly payment required to pay off a loan based on a fixed interest rate, loan amount, and loan tenure.
- Syntax:
=PMT(rate, nper, pv, [fv], [type])- rate: The interest rate for each period.
- nper: The total number of payment periods.
- pv: The present value (loan amount).
- fv: Future value, which is an optional argument (usually set to 0 for loans).
- type: The timing of the payment (optional; 0 for end of the period, 1 for beginning).
- PPMT Function
- The PPMT function calculates the principal portion of a payment for a particular period in a loan.
- Syntax:
=PPMT(rate, per, nper, pv, [fv], [type])- per: The period for which the principal is being calculated (e.g., 1st, 2nd, 3rd month, etc.).
- IPMT Function
- The IPMT function calculates the interest portion of a payment for a specific period.
- Syntax:
=IPMT(rate, per, nper, pv, [fv], [type])
How to Use These Functions
Let’s go through a practical example to understand how these functions work.
Scenario: Home Loan in India
Imagine you have a home loan of ₹50,00,000 (₹50 Lakhs) at an annual interest rate of 8% for a 20-year tenure. You want to calculate the following:
- The monthly payment using the PMT function.
- The principal and interest portion for the 5th month using the PPMT and IPMT functions.
Step-by-Step Guide
1. Prepare Your Data
Create the following table in Excel:
| Loan Amount | ₹50,00,000 |
| Annual Interest Rate | 8% |
| Loan Tenure (Years) | 20 years |
| Monthly Interest Rate | 8% ÷ 12 = 0.67% |
| Total Number of Payments | 20 × 12 = 240 |
2. Use the PMT Function to Calculate Monthly Payment
To calculate the monthly payment (EMI), you can use the PMT function:
=PMT(0.08/12, 20*12, -5000000)
Explanation:
- 0.08/12: Monthly interest rate (annual rate divided by 12).
- 20*12: Total number of payments (20 years × 12 months).
- -5000000: Loan amount (negative because it represents money owed).
This will return a result of ₹41,558.55 (EMI).
3. Use the PPMT Function to Calculate the Principal Portion of the 5th Payment
To calculate how much of the 5th monthly payment goes toward the principal, use the PPMT function:
=PPMT(0.08/12, 5, 20*12, -5000000)
Explanation:
- This indicates that you want to calculate the principal payment for the 5th month.
This will return ₹40,384.72, which is the principal portion of the 5th payment.
4. Use the IPMT Function to Calculate the Interest Portion of the 5th Paymen
Similarly, to calculate the interest portion of the 5th payment, use the IPMT function:
=IPMT(0.08/12, 5, 20*12, -5000000)
This will return ₹26,615.28, which is the interest portion of the 5th payment.

| 3 | ₹41,558.55 | ₹41,203.59 | ₹25,796.41 | ₹48,77,617.68 |
| 4 | ₹41,558.55 | ₹41,613.22 | ₹25,386.78 | ₹48,36,004.46 |
| 5 | ₹41,558.55 | ₹40,384.72 | ₹26,615.28 | ₹47,95,519.74 |
When and Why to Use These Functions
- PMT:
- When to use: Whenever you need to calculate the monthly installment (EMI) for a loan with fixed terms.
- Why to use: It saves time and effort by directly calculating the EMI without needing a manual approach.
- PPMT:
- When to use: When you want to break down the EMI into principal and interest portions for specific payment periods.
- Why to use: It’s essential for financial planning as it helps you see how much of your payment is going toward reducing the principal, especially in the early stages of the loan when most of the payment goes toward interest.
- IPMT:
- When to use: When you need to determine how much of the payment goes toward interest for a specific period.
- Why to use: It’s crucial for understanding the cost of borrowing, as you can track how much interest you’re paying over time and plan accordingly.
