The calculator provides four important outputs.
Monthly Payment
This is the amount you must pay each month toward your mortgage.
It includes:

Mortgage Payment Formula
Mortgage calculations are based on the standard amortization formula.
The monthly mortgage payment is calculated using:
M=P×(1+r)n−1r(1+r)n
Where:
- M = Monthly payment
- P = Loan amount
- r = Monthly interest rate
- n = Total number of monthly payments
Monthly Interest Rate Formula
r=12×100Annual Interest Rate
Number of Payments Formula
n=Loan Term in Years×12
