Visual breakdown
How it works
EMI = P × r × (1+r)^n / ((1+r)^n − 1)
- 1Monthly rate r = 8.5% ÷ 12 ÷ 100 = 0.007083
- 2Number of payments n = 240
- 3EMI = P × r × (1+r)^n / ((1+r)^n − 1) = 4,339.12
- 4Total interest = (EMI × n) − P = 541,387.88
How the emi calculator works
EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), with r as the monthly rate and n as the number of monthly payments.
Total interest = EMI × n − P. The tool shows both so the instalment is never read in isolation.
For a rough mental check, an instalment on a 10-year loan at around 9% lands near 1.27% of the principal per month — useful for sanity-checking a quote on the spot.
Worked example: 250,000 personal loan at 12% over 5 years
- r = 12 ÷ 1,200 = 0.01, n = 60.
- (1.01)^60 ≈ 1.8167.
- EMI = 250,000 × 0.01 × 1.8167 ÷ 0.8167 ≈ 5,561.
- Total repayment = 5,561 × 60 = 333,660, so interest is about 83,660 — a third of the amount borrowed.
Common mistakes to avoid
Quoting tenure in years into a monthly formula
n must be months. Five years is 60, not 5; the mismatch is the most frequent cause of an implausible instalment.
Ignoring the difference between rate and APR
APR includes processing fees. On small, short loans a 2% fee can add more than a percentage point of effective cost.
Frequently asked questions
What does EMI stand for?
Equated monthly instalment — a fixed payment covering interest on the current balance plus a slice of principal.
Can I calculate EMI without a formula?
Only approximately. Simple-interest shortcuts understate the payment because they ignore the reducing balance, so use the amortisation formula for anything you plan to sign.
How is EMI different from a mortgage payment?
The arithmetic is identical. A mortgage bill usually adds escrowed taxes and insurance on top of the EMI-equivalent principal and interest.
Does the first EMI include extra charges?
Often. Lenders may collect interest for the broken period between disbursal and the first due date, so the opening debit can exceed the quoted instalment.
