How the Personal Loan EMI Calculator Works
Personal loans are unsecured, so lenders charge higher rates than they would on a home or car loan. Rates commonly range from about 10% to 24% a year, depending on your credit score, income and employer.
Enter the loan amount, the quoted annual interest rate and your preferred tenure — usually 1 to 5 years, occasionally up to 7.
The calculator uses the reducing-balance method, so each instalment covers that month's interest first and the rest goes toward clearing your principal.
Watch what happens when you stretch the tenure. The EMI drops, but the total interest climbs sharply, which is the main trade-off on any unsecured loan.
Formula Used
Personal loan EMI uses the standard reducing-balance formula:
EMI = P × r × (1+r)^n / ((1+r)^n − 1)- PPersonal loan principal amount
- rMonthly interest rate (annual rate ÷ 12 ÷ 100)
- nTotal number of monthly instalments (tenure in years × 12)
Example Calculation
Suppose you borrow 5,00,000 for 4 years at a 14% annual interest rate.
- Loan Amount500,000
- Interest Rate14% p.a.
- Tenure4 years
- ResultMonthly EMI ≈ 13,663 (Total Interest: ≈ 155,835)
Important Assumptions
- Interest is calculated on a reducing monthly balance, the method used by banks and NBFCs for personal loans.
- The interest rate stays fixed for the entire tenure, which is standard for personal loans.
- Processing fees (typically 1–3% of the loan), GST on those fees, and any insurance charges are not included — these are usually deducted upfront, so the amount credited to your account may be less than the sanctioned amount.
- Foreclosure and part-payment charges, which many lenders levy on personal loans, are not included.
