Loan Calculator
Calculate an annuity loan: monthly payment, total interest and a full month-by-month payment schedule. Any currency, instant, right in your browser.
Why calculate a loan in advance
A loan offer usually shows the rate — but what matters for your budget is the monthly payment and how much the money will cost in total. This calculator converts amount, rate and term into a concrete payment, shows the interest share, and lays out the full schedule so you can see how the debt shrinks month by month.
What it does
- Annuity monthly payment — the equal-payment scheme most banks use.
- Total cost and the interest share of every payment.
- A full month-by-month schedule: interest vs principal and the remaining balance.
How to use
- Enter the loan amount, annual rate and term in months.
- Pick a currency symbol and read the monthly payment and totals.
- Open the payment schedule to see how each payment splits into interest and principal.
How it works
The calculator uses the standard annuity formula: payment = P × i × (1+i)ⁿ / ((1+i)ⁿ − 1), where i is the monthly rate and n the number of months. Every row of the schedule is derived from the previous balance. Everything is computed locally in your browser.
Frequently asked questions
What is an annuity payment?
A scheme where you pay the same amount every month: early payments are mostly interest, later ones mostly principal. It is the default for most consumer loans and mortgages.
Does the calculator include fees and insurance?
No — it models only the principal and the interest rate. If your bank charges monthly fees, add them to the payment mentally, or include them in the rate for a rough estimate.
