Estimate EMI using principal, interest, and tenure.
Quick answer: Loan Calculator
Monthly payment = P x [r(1+r)^n] / [(1+r)^n - 1], where P is principal, r is monthly rate, and n is the number of payments.
Example: A GBP 10,000 loan at 6% APR over 3 years is about GBP 304 per month before fees.
Calculations follow the documented formula on this page; rounding and input units can change the last digit-treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
Amortization front-loads interest; early payments barely dent principal. Use extra-payment mode if the tool exposes it to see leverage of rounding up.
