How it's calculated

Monthly Payment

loan_amount * (annual_interest_rate / 100 / 12) * Math.pow(1 + annual_interest_rate / 100 / 12, loan_term_years * 12) / (Math.pow(1 + annual_interest_rate / 100 / 12, loan_term_years * 12) - 1)

Fixed monthly payment for principal and interest

Total Amount Paid

loan_amount * (annual_interest_rate / 100 / 12) * Math.pow(1 + annual_interest_rate / 100 / 12, loan_term_years * 12) / (Math.pow(1 + annual_interest_rate / 100 / 12, loan_term_years * 12) - 1) * loan_term_years * 12

Total of all payments over the loan term

Total Interest Paid

loan_amount * (annual_interest_rate / 100 / 12) * Math.pow(1 + annual_interest_rate / 100 / 12, loan_term_years * 12) / (Math.pow(1 + annual_interest_rate / 100 / 12, loan_term_years * 12) - 1) * loan_term_years * 12 - loan_amount

Frequently Asked Questions

How is the monthly mortgage payment calculated?

The monthly payment uses the standard amortization formula: M = P × [r(1+r)^n] / [(1+r)^n - 1], where P is the loan amount, r is the monthly interest rate, and n is the total number of payments.

Should I choose a shorter or longer loan term?

A shorter term means higher monthly payments but significantly less total interest paid. A longer term lowers monthly payments but increases total cost. Choose based on your monthly cash flow capacity.

Are property taxes and insurance included in this calculation?

No, this calculator only computes the principal and interest amounts. You should definitely budget separately for additional costs like property taxes, comprehensive home insurance, and monthly maintenance fees.

What happens if interest rates fluctuate?

This calculator assumes a fixed interest rate throughout the entire loan term. If your bank uses a floating rate after the initial promotional period, your actual monthly payments will vary accordingly.

Can paying off my mortgage early save me money?

Yes, absolutely! Making additional principal payments or fully paying off your home loan ahead of the scheduled timeframe can significantly drastically reduce the total amount of interest you will be charged over the years. However, you should always consult your specific loan agreement closely, as many banking institutions impose prepayment penalties for early settlement.
