What is the Loan Calculator?
Enter your loan amount, annual interest rate, and term, and it instantly shows your monthly payment, the total interest you'll pay, and the total amount you'll repay.
Before taking out a mortgage, car loan, or student loan, you can see how heavy the real burden will be — helping you avoid overborrowing and compare options wisely.
Equal payment vs. equal principal
With the equal-payment (annuity) method, you pay the same amount every month from start to finish, which makes budgeting simple.
With the equal-principal method, you repay the principal in equal parts plus interest on the remaining balance. Payments start higher and shrink over time, and the total interest ends up slightly lower.
How to use it
Try lowering the rate by just 0.5%p and watch how much total interest you save.
A longer term lowers the monthly payment but raises the total interest — use it to find the balance that fits you.
Tap 'View schedule' to see how each payment splits between principal and interest, month by month.
Frequently Asked Questions
Are the results the same as a real loan?
The math (equal payment / equal principal) matches how banks calculate, but real loans can differ slightly due to fees, prepayment, or preferential rates — use it as a guide.
How do I lower my monthly payment?
Get a lower rate or extend the term. Keep in mind that a longer term increases the total interest paid.
Can I use other currencies?
Yes — tap the amount's unit to switch between USD, KRW, JPY, EUR, and many more.
