Frequently asked questions

Which calculator should I use for a personal loan?
Use the Loan Calculator for personal, car or business loans — enter the amount, rate and term to see the repayment, total interest and full schedule.
How is compound interest different from simple interest?
Simple interest is charged only on the original amount; compound interest is charged on the balance including previously added interest, so it grows faster. The Compound Interest calculator shows the difference.
