A monthly loan payment is not found by simply dividing the amount by the number of months. Interest is charged on the outstanding principal and the repayment method determines how each payment is split.
What is an annuity payment?
With an annuity schedule the monthly payment normally remains level. Early payments contain more interest; as the balance falls, a larger share goes to principal.
The monthly payment formula
A = P × r × (1+r)n / ((1+r)n − 1), where P is principal, r is the monthly rate, n is the number of months and A is the payment. A 12% nominal annual rate corresponds to 1% per month, represented as 0.01 in the formula.
10,000 AZN for 36 months
At a 12% nominal rate, the monthly payment is approximately 332.14 AZN. Total scheduled repayments are about 11,957.15 AZN and interest is 1,957.15 AZN before fees and insurance. Use the loan calculator to change the assumptions and see the full chart.
How the term changes the result
A longer term spreads principal across more months and lowers the payment, but interest is charged for longer. A shorter term increases the monthly burden while often reducing lifetime interest.
Common calculation mistakes
- using the annual rate as a monthly rate;
- entering years where the formula expects months;
- ignoring fees and insurance;
- choosing a long term based only on the monthly figure.
