How to calculate your monthly mortgage payment?
To calculate your monthly mortgage payment, you can use the following formula:
Monthly Payment (M) is calculated as:
§§ M = P \times \frac{r(1 + r)^n}{(1 + r)^n - 1} §§
where:
- § M § — monthly payment
- § P § — principal loan amount (loan amount minus down payment)
- § r § — monthly interest rate (annual interest rate divided by 12)
- § n § — number of payments (loan term in months)
This formula allows you to determine how much you will need to pay each month to repay your mortgage over the specified term.
Example:
- Loan Amount (§ P §): $200,000
- Annual Interest Rate: 3.5%
- Loan Term: 30 years
- Down Payment: $40,000
First, calculate the principal:
§§ P = 200,000 - 40,000 = 160,000 §§
Next, convert the annual interest rate to a monthly rate:
§§ r = \frac{3.5}{100} \div 12 = 0.00291667 §§
Then, calculate the number of payments:
§§ n = 30 \times 12 = 360 §§
Now, plug these values into the formula:
§§ M = 160,000 \times \frac{0.00291667(1 + 0.00291667)^{360}}{(1 + 0.00291667)^{360} - 1} ≈ 718.43 §§
So, your monthly mortgage payment would be approximately $718.43.
