How our finance calculators work

Each of our finance calculators uses standard, published formulas – the same ones banks and textbooks use – and shows every step under the result. Rates, taxes and fees differ between countries and lenders, so treat the results as estimates and confirm the final figures with your bank or adviser.

You can switch the currency on every calculator between dollars, rupees, pounds, euros, dirhams and riyals. Your numbers are worked out in your browser and are not sent to us.

Frequently asked questions

Are these finance calculators free?

How accurate are the finance calculators?

They use standard formulas and are checked against worked examples shown on each page. Real offers may differ because of fees, taxes and rounding by lenders.

Do the calculators work in Pakistan, India and other countries?

Yes. Choose your currency and enter local rates. Country-specific tools such as income tax and zakat are being added to the Pakistan section.

Which calculator should I use for a home loan?

Use the Mortgage Calculator. It adds property tax, insurance, HOA and PMI to the loan payment.

What is the difference between simple and compound interest?

Simple interest is charged only on the principal; compound interest also charges interest on past interest, so it grows faster.

No. Calculations run in your browser and are not sent to our servers.

Are the results financial advice?

No. They are estimates to help you plan. For decisions about loans or investments, speak to a qualified adviser or your bank.
