Mortgage Payment
What Is a Mortgage?
A mortgage is a type of loan used to purchase real estate. Typically, it involves:
- Principal: The amount borrowed from the lender.
- Interest Rate: The cost of borrowing, expressed as an annual percentage.
- Loan Term: The number of years you’ll repay the mortgage.
Mortgage payments usually include a combination of principal repayment and interest. Understanding how these factors affect your monthly and total payments is key to effective financial planning.
How the American Mortgage Calculator Works
The calculator uses a standard mortgage formula to determine your monthly payment:M=P(1+r)n−1r(1+r)n
Where:
- M = Monthly payment
- P = Loan principal
- r = Monthly interest rate (annual rate ÷ 12)
- n = Total number of payments (loan term in years × 12)
It also calculates:
- Total Payment: The total amount paid over the life of the loan, including principal and interest.
- Total Interest: The total interest paid to the lender over the loan term.
By using this calculator, you can quickly see how loan amount, interest rate, and term length affect your mortgage.

Example Calculation
Suppose:
- Loan Amount: $300,000
- Annual Interest Rate: 5%
- Loan Term: 30 years
Calculation:
- Monthly interest rate: 5 ÷ 12 ÷ 100 = 0.004167
- Total payments: 30 × 12 = 360 months
- Monthly Payment:
M=300,000(1+0.004167)360−10.004167(1+0.004167)360≈1,610.46
- Total Payment: $1,610.46 × 360 = $579,765.60
- Total Interest: $579,765.60 − $300,000 = $279,765.60
This demonstrates how interest significantly impacts long-term costs.
