How this calculation works
Fixed nominal annual interest divided by 12, with equal end-of-month payments. Payment = P × r / (1 − (1 + r)^−n). At zero interest, payment = P / n. Rates stay constant; fees, penalties and variable-rate changes are excluded. The final payment clears the remaining balance. Calculations retain precision internally; displayed and exported amounts are rounded to two decimals.
Worked example
10,000 borrowed at 8% per year for 10 months gives a monthly payment of approximately 1,037.03, before fees.
