Breaking Down Your Mortgage Payment
A mortgage payment consists of several components that determine the total amount due each month. Understanding these components will help you plan your finances better.
Mortgage Payment Components
- Principal: The amount borrowed from the lender.
- Interest: The lender’s charge for borrowing money.
- Taxes: Property taxes set by local authorities.
- Insurance: Homeowners insurance, and possibly mortgage insurance.
How Mortgage Payments Are Calculated
Mortgage payments are based on a formula that takes into account the loan amount, interest rate, and loan term. The formula is as follows:
M = P[r(1+r)^n] / [(1+r)^n – 1]
Where: - M = Monthly payment - P = Loan principal - r = Monthly interest rate (annual rate ÷ 12) - n = Total number of payments (years × 12)
Example Calculation
Consider a $300,000 loan at 6% interest over 30 years.
- Loan amount: $300,000
- Annual interest rate: 6% (0.06/12 = 0.005 monthly rate)
- Loan term: 30 years (360 payments total)
Plugging these values into the formula:
M = 300,000 [0.005(1.005)^360] / [(1.005)^360 – 1]M = $1,798 per month
