The calculator will display your monthly payment, total interest paid, and total amount paid over the life of the loan. You can also view a payment schedule chart.
Mortgage Calculation Formula
The monthly mortgage payment is calculated using the following formula:
Monthly Payment = P × [r(1 + r)^n] / [(1 + r)^n - 1]
Where:
- P = Principal loan amount (loan amount minus down payment)
- r = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in years × 12)
This formula uses the standard amortization method where equal payments are made each month, including principal and interest.
Worked Example
Let's calculate a mortgage for a $300,000 loan with a 4.5% interest rate over 30 years:
- Principal (P) = $300,000
- Annual interest rate = 4.5% or 0.045
- Monthly interest rate (r) = 0.045 / 12 = 0.00375
- Number of payments (n) = 30 × 12 = 360
Plugging these values into the formula:
Monthly Payment = $300,000 × [0.00375(1 + 0.00375)^360] / [(1 + 0.00375)^360 - 1]
Calculating this gives a monthly payment of approximately $1,618.50.
Over 30 years, you would pay a total of $582,660, with $182,660 in interest.
Understanding Mortgage Terms
Key terms to know when using this calculator:
- Principal
- The amount borrowed for the mortgage.
- Interest Rate
- The percentage charged by the lender for borrowing the money.
- Loan Term
- The length of time to repay the loan, typically 15, 20, or 30 years.
- Down Payment
- The amount paid upfront, typically 3-20% of the home price.
- Monthly Payment
- The amount paid each month, including principal and interest.
Comparing Mortgage Options
Use this table to compare different mortgage scenarios:
| Loan Amount | Interest Rate | Loan Term | Monthly Payment | Total Interest |
|---|---|---|---|---|
| $300,000 | 4.5% | 15 years | $2,375.42 | $112,660 |
| $300,000 | 4.5% | 20 years | $1,985.30 | $142,660 |
| $300,000 | 4.5% | 30 years | $1,618.50 | $182,660 |
| $300,000 | 5.0% | 30 years | $1,710.15 | $202,660 |
Shorter loan terms result in higher monthly payments but lower total interest. Higher interest rates increase both monthly payments and total interest.
