How to Calculate the Cost of a Mortgage?

The cost of a mortgage can be calculated using the following formula for monthly payments:

For Annuity Payments:

§§ M = P \times \frac{r(1 + r)^n}{(1 + r)^n - 1} §§

Where:

  • § M § — monthly payment
  • § P § — loan amount (principal)
  • § r § — monthly interest rate (annual interest rate divided by 12)
  • § n § — total number of payments (loan term in months)

Example:

  • Loan Amount (§ P §): $200,000
  • Annual Interest Rate: 3.5%
  • Loan Term: 30 years

First, convert the annual interest rate to a monthly rate:

§§ r = \frac{3.5}{100} \div 12 = 0.00291667 §§

Then, calculate the total number of payments:

§§ n = 30 \times 12 = 360 §§

Now, plug these values into the formula:

§§ M = 200000 \times \frac{0.00291667(1 + 0.00291667)^{360}}{(1 + 0.00291667)^{360} - 1} \approx 898.09 §§

Thus, the monthly payment would be approximately $898.09.
