Understanding Loan EMI
How we calculate. EMI = P × r × (1+r)^n / ((1+r)^n − 1), where r is monthly rate and n is months. The form uses the same arithmetic as the worked examples on this page. See our methodology and accuracy policy.
Real-world scenario: A typical Loan EMI case uses loan principal 100000 and annual interest rate (%) 10. Enter the same figures below to reproduce the worked path.
What is Loan EMI?
Standard amortizing loan payment used for personal loans, auto loans, and many mortgages. Assumes a fixed rate and monthly compounding of the contractual rate.
- r = annual rate ÷ 12 ÷ 100
- n = tenure in months
- Total interest = EMI × n − P
The Formula
Worked Example
Common Use Cases
- Personal loans: compare offers
- Auto financing: payment fit vs budget
- Mortgage ballparks: first-pass payment estimates
Pro Tips
- Fees are excluded unless you add them to principal
- Prepayment changes remaining interest—not shown here
- Confirm day-count conventions with your lender
Limitations: Loan EMI results are educational finance aids—not loan offers, investment advice, or tax counsel. Confirm figures with a qualified professional and your contract.
FAQ
Is this the same as simple interest?
No. EMI uses reducing balance amortization. Simple interest uses P × rate × time without amortization.
What if the rate is 0%?
EMI becomes principal ÷ months (equal principal splits with no interest).
