FAQ
About loans & instalment credit
How is the monthly loan payment calculated?
An instalment (annuity) loan has a constant monthly payment derived from the loan amount, the nominal interest rate and the term. Early on most of the payment is interest; later, more of it repays the principal.
What is the difference between nominal rate and APR?
The nominal rate is the pure interest on the loan. The APR (effective annual rate) also includes fees and the payment schedule, so it is usually higher. This calculator uses the nominal rate – compare offers by their APR.
How can I lower the monthly payment?
A longer term lowers the monthly payment but raises the total interest. A lower rate or a smaller amount reduces both. Try different terms to see the trade-off.
Is my data stored?
