About this calculator
Estimate fixed monthly repayments for an amortising loan.
This excludes fees, insurance, taxes and lender-specific rules.
Formula
Monthly payment = P × i(1+i)^n ÷ ((1+i)^n − 1), where i is monthly rate.
Example
10,000 over 5 years at 6% gives a payment around 193/month.
Accuracy
NUMTX shows the assumptions next to the calculation so you can replace defaults with values that match your situation. For measurements, supplier rates, fees, interest, tax or regulated work, confirm important figures with the appropriate official or professional source.
