How This Personal Loan Calculator Works

A personal loan is amortized: every monthly payment covers that month's interest first, and the rest reduces the principal. The monthly payment (EMI) is fixed for the whole term, so the interest share shrinks and the principal share grows as the balance falls.

Worked example: $20,000 borrowed at 8% annual interest for 5 years (60 payments). Monthly rate = 0.08 ÷ 12 = 0.006667. EMI = $405.53 per month, total paid = $24,331.67, so total interest = $4,331.67 — about 22% of the amount borrowed.

Practical tips

A lower rate beats a shorter term — usually.

Dropping the rate by 1 percentage point saves more than shaving a year off the term on most loans. Compare offers by APR, not by the monthly payment alone.

Watch the origination fee.

Some lenders charge 1–8% of the loan up front. A loan with a low rate and a big fee can cost more than a slightly higher rate with no fee — add the fee to the total paid before comparing.

Extra payments cut interest directly.

Any extra payment goes straight to principal (confirm your lender applies it that way). Even $25 extra a month shortens the term and the total interest.

Never borrow for the monthly payment alone.

A longer term lowers the EMI but raises total interest. Pick the shortest term whose payment fits your budget comfortably.
