How it works

  1. 1Choose a calculator from the list.
  2. 2Select your currency and fill in the numbers.
  3. 3Read the results, then change an input to compare scenarios.

Calculators for borrowing

The EMI calculator takes a loan amount, an interest rate and a term, and returns your monthly payment, the total interest and a full amortization table in monthly and yearly views. Use it before you sign for a home, car or personal loan, and compare the total interest across terms rather than looking only at the monthly figure.

Seeing the schedule also shows how much of each early payment goes to interest, which helps you decide whether an extra payment is worth making.

Calculators for saving and investing

Compound interest shows how a balance grows when interest earns interest, with monthly contributions, five compounding frequencies and a chart. The SIP and savings goal calculator answers two questions: what a monthly investment grows into, and how much per month you need to reach a target by a date.

Both depend on the return you assume. Try a cautious rate and a hopeful one, and plan around the lower result. A realistic range is more useful than a single number.

Everyday money math

The percentage calculator handles three questions: X percent of Y, the percent change from one value to another, and what percent one number is of another. It is useful for tips, grades, price changes and salary raises.

The discount calculator adds sales tax or GST. It shows the sale price, the amount you save and the final total, and it can treat the price as tax-inclusive or tax-exclusive. That helps when you compare shops, check an invoice or split GST out of a total.

Estimates, not advice

These tools give estimates based on the numbers you enter. They leave out fees, taxes, changing rates and the rules of a particular lender or bank. Use them to understand your options and to prepare questions, and rely on official documents for final figures.

Nothing you type is sent anywhere. The calculations run in your browser, and you can pick a currency such as dollars, rupees, pounds or euros to match your situation.
