About the Loan Calculator
Before you sign for any loan, one number matters most: the monthly payment, and what it adds up to over the full term. A loan that looks affordable month to month can quietly cost a small fortune in interest by the time it is paid off.
This Loan Calculator shows your monthly payment, the total interest and the total cost in seconds, using the same standard formula lenders use. Change the amount, rate or term and watch the numbers move, so you can compare offers properly and borrow with your eyes open.
How to use the Loan Calculator
- Enter the loan amount you want to borrow.
- Add the annual interest rate offered.
- Set the loan term in months or years.
- Read your monthly payment, total interest and total cost instantly.
Key features of the Loan Calculator

- Any currency — the maths is the same worldwide

How the Loan Calculator works
This calculator uses the established mathematical formulas that banks, lenders and financial institutions rely on — for interest, amortization, EMI, compounding, tax and investment growth. Where local rules apply (such as tax bands or GST/VAT rates), the tool follows the relevant published structure, and figures can be expressed in the currency you work in.
Every calculation runs in your browser, so the financial figures you enter stay completely private.
Tips & best practices
- Compare loans on total cost, not just the monthly payment — a longer term lowers the monthly figure but usually costs far more in interest.
- Even a small difference in interest rate adds up over a long term, so it is worth shopping around and negotiating.
- If you can afford a higher payment, a shorter term saves a significant amount overall.
Standards & accuracy
Uses the same standard financial formulas as banks and lenders, with support for multiple currencies and international tax rules.
