Formula Used
The mortgage payment is calculated using the standard mortgage formula:
Where:
- M = Monthly payment
- P = Principal loan amount
- i = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in years multiplied by 12)
This formula calculates the fixed monthly payment required to pay off a loan with compound interest.
Worked Example
Let's calculate a mortgage payment for a $200,000 loan at 4% annual interest for 30 years.
- Convert the annual interest rate to a monthly rate: 4% ÷ 12 = 0.3333% or 0.003333 in decimal form.
- Calculate the number of payments: 30 years × 12 = 360 payments.
- Plug the values into the formula:
M = $200,000 [ 0.003333(1 + 0.003333)^360 ] / [ (1 + 0.003333)^360 - 1 ]
- The calculation yields a monthly payment of approximately $1,073.64.
Over 30 years, you would pay a total of $386,510.40, with $86,510.40 going toward interest.
Frequently Asked Questions
What is a mortgage payment?
A mortgage payment is the amount you pay each month to your lender to repay your home loan. This payment includes principal (the amount borrowed) and interest (the cost of borrowing).
How is the interest rate calculated?
The interest rate is calculated as a percentage of the outstanding loan balance. It is typically expressed as an annual percentage rate (APR) and is divided by 12 to get the monthly interest rate.
What is the difference between fixed and adjustable-rate mortgages?
A fixed-rate mortgage has the same interest rate and monthly payment for the life of the loan. An adjustable-rate mortgage (ARM) has an initial fixed rate that changes after a certain period, typically 5, 7, or 10 years.
