Loan and savings maths, done properly.
EMI, fixed deposit, recurring deposit and SIP calculators that know what banks in India, the United States and the GCC actually charge — and show you the gap between the cheapest lender and the most expensive one, in money.
Pick a calculator, pick a country
Change the country and the currency, the rate defaults and the entire bank list change with it. Everything recalculates as you drag.
Loading the calculator…
Most calculators stop at the number
A monthly instalment on its own does not tell you very much. These four things are what turn it into a decision.
The lender spread
The same loan priced at every bank in your country, cheapest first, with the total cost difference across the whole term spelled out. It is usually larger than people expect.
Prepayment, modelled
Add a little every month, or drop a lump sum in month 14. The schedule is rebuilt against the real falling balance, so the interest saved and months cut are exact.
Year-by-year truth
Hover any year to see how much of that year went to principal and how much evaporated as interest. Early years are brutal, and the chart does not hide it.

Eight markets, one calculator
Currency, number formatting, compounding convention and the lender list all switch together when you change country.
How an EMI is actually calculated
An equated monthly instalment is the fixed payment that clears a loan exactly at the end of its term. It is the same amount every month, but what that amount does changes constantly: early on it is mostly interest, and only in the back half does it start seriously eating the principal.
- P — the principal, what you actually borrow after any down payment.
- r — the monthly rate, which is the annual rate divided by 12 and then by 100. An 8.5% loan has an r of 0.00708.
- n — the number of monthly instalments. A 20-year loan is 240, not 20.
Dividing the annual rate by twelve is the part people get wrong. A 9% loan is not 9% a month and it is not 0.9% a month — it is 0.75% a month, applied to a balance that shrinks a little with every payment.
Why the first years feel like nothing is happening
Interest each month is charged on whatever is still outstanding. In month one of a 20-year home loan, almost the entire balance is outstanding, so almost the entire instalment is interest. The chart in the calculator makes this visible: drag the tenure from 20 years to 15 and watch how much of the total shifts from the interest bar to the principal bar.
Longer tenure, smaller instalment, much bigger bill
Stretching a loan lowers the monthly number, which is exactly why lenders offer it. It also increases the total you repay, sometimes dramatically. Set up your loan in the calculator, note the total payable at 25 years, then drag it to 15 — the monthly figure rises, and the total falls by an amount that is often a large fraction of the original principal.
Fixed deposits, recurring deposits and compounding
On the savings side the same arithmetic runs in reverse. A fixed deposit compounds a lump sum; a recurring deposit compounds a stream of monthly instalments, each of which has less time to grow than the one before it. Compounding frequency matters more than people assume — the same nominal rate compounded quarterly beats the same rate compounded annually, every time.
Indian banks conventionally compound fixed deposits quarterly, US CDs are quoted as an APY that has the compounding already baked in, and GCC term deposits vary by bank. The calculator lets you set the frequency explicitly and shows you what the difference is worth in money.

Eight markets: India, the United States, and all six GCC states — the UAE, Saudi Arabia, Qatar, Kuwait, Bahrain and Oman. That is 57 lenders in total, including public sector banks, private banks, online-only banks, Indian NBFCs and Sharia-compliant Islamic banks.
They are indicative starting rates taken from published rate cards, stamped with the date they were compiled. They are a fair basis for comparison, not a quote. Your real rate depends on credit history, income, loan-to-value and any relationship pricing, so always confirm with the lender before you commit.
Sharia-compliant financing is structured as a sale or lease — murabaha or ijara — rather than a loan at interest. The monthly instalment arithmetic works out the same way, which is why the calculator can handle both, but the contract, the ownership arrangement and the early-settlement rules are genuinely different. We label those banks so you know which you are looking at.
Yes. Every input is written into the page URL as you type, so copying the link — there is a Copy link button next to the result — reopens the calculator with exactly the same numbers on any device.
It handles both at once: a fixed extra amount added to every instalment, and a single lump sum paid in a month you choose. The schedule is recomputed month by month against the falling balance, so the interest saved and the months cut off the term are the real figures, not an approximation.
