Before applying for any loan, one of the most important things to understand is how much you will need to pay every month. This monthly payment is known as EMI, or Equated Monthly Installment.
Many borrowers struggle with EMI calculation because it involves mathematical formulas and interest rate conversions. Fortunately, modern online tools make EMI calculation extremely simple.
In this guide, you will learn how to calculate loan EMI step by step, both manually and using online EMI calculators.
What Is Loan EMI?
Loan EMI is the fixed amount paid by a borrower to the lender every month until the loan is fully repaid.
Each EMI consists of:
- Principal repayment
- Interest payment
While the EMI amount usually remains constant, the proportion of principal and interest changes over time.
Why Is EMI Calculation Important? How to calculate loan EMI
Calculating EMI before taking a loan helps you:
- Understand monthly financial commitment
- Avoid over-borrowing
- Plan your monthly budget
- Compare different loan offers
- Prevent loan repayment stress
Knowing your EMI in advance leads to smarter financial decisions.
Method 1: Manual EMI Calculation
The EMI formula is:
EMI = P × R × (1 + R)^N / [(1 + R)^N – 1]
Where:
- P = Loan amount
- R = Monthly interest rate
- N = Loan tenure in months
Although this formula is accurate, manual calculation can be confusing for most borrowers.

The easiest way to calculate EMI is by using an online EMI calculator.
Steps to calculate EMI online:

This method is fast, accurate, and user-friendly.
Example of Loan EMI Calculation
Let us understand with an example:
Loan Amount: $15,000
Interest Rate: 8.5% per annum
Tenure: 4 years
Using an online EMI calculator:
- Monthly EMI ≈ $381
- Total interest ≈ $3,300
- Total repayment ≈ $18,300
This example shows how EMI calculation provides clarity before borrowing.
Factors That Affect Loan EMI
1. Loan Amount
Higher loan amount increases EMI.
2. Interest Rate
Even a small change in interest rate significantly impacts EMI.
3. Loan Tenure
Longer tenure lowers EMI but increases total interest.
4. Interest Type
Fixed or floating interest affects EMI behavior.
EMI Calculation Using Reducing Balance Method
Most banks and lenders use the reducing balance method.
Under this method:
- Interest is calculated on remaining loan balance
- Interest portion decreases over time
- Principal repayment increases gradually
This method is more borrower-friendly than flat interest calculation.
