EMI is the same amortisation maths used worldwide — a fixed monthly payment where the interest share falls and the principal share rises over time. In the early years most of your payment is interest.
How it works
The calculation runs in your browser as you type — there is no submit button and nothing is sent anywhere. Change any figure and the results update immediately, which makes it easy to see how sensitive the answer is to each input.
Every formula used here is standard and documented in the questions below. Where a result depends on an assumption, the assumption is stated rather than buried.
Frequently asked questions
What is EMI?
Equated Monthly Instalment — a fixed monthly amount covering both interest and principal, calculated so the loan clears exactly at the end of the term.
Why is so much of my early EMI interest?
Interest is charged on the outstanding balance, which is highest at the start. On a 20-year loan, roughly 70% of your first year of payments typically goes to interest.
Does prepaying help?
Substantially, and most in the early years, because a prepayment removes principal that would otherwise accrue interest for the remaining term.
Is this calculator free?
Yes, with no account, no limits and no data collection. It runs entirely in your browser.
Should I rely on this for a financial or medical decision?
No. It is a planning estimate built on standard formulas and stated assumptions. For decisions that matter, speak to a qualified professional who can account for your full circumstances.
Is this calculator accurate?
The arithmetic is exact — it uses the standard formula, shown in the questions above. What limits accuracy is the assumptions: the figures you enter, and factors the formula does not model such as fees, taxes and rule changes. Treat the result as a well-founded estimate rather than a quotation.
Do I need to sign up or download anything?
No. It runs in your browser, updates as you type, and stores nothing. There is no account, no download, and no limit on how many times you use it.
