How Are Mortgage Payments Calculated Formula?

For most people, buying a home is one of the biggest financial decisions they will make in their lifetime. When obtaining a mortgage loan, it is crucial to understand how mortgage payments are calculated. This knowledge helps potential homeowners determine how much they can afford and choose the right loan terms. Mortgage payments are typically calculated using a formula that takes into account the loan amount, interest rate, and loan term.

The formula used to calculate mortgage payments is known as the amortization formula. It is composed of three main components: the loan amount (principal), the interest rate, and the loan term. The formula is as follows:

M = P [i(1 + i)^n] / [(1 + i)^n – 1]

Where:
M = Monthly mortgage payment
P = Principal loan amount
i = Monthly interest rate (annual interest rate divided by 12)
n = Number of monthly payments

By plugging in the appropriate values into this formula, borrowers can calculate their monthly mortgage payment. For example, let’s assume a borrower has a \$200,000 loan with a 4% interest rate and a 30-year term. Plugging these values into the formula would yield a monthly mortgage payment of approximately \$954.
