How to Calculate Mortgage Payments
The mortgage payment formula is:
Where:
- M = Monthly payment
- P = Principal loan amount
- r = Monthly interest rate (annual rate ÷ 12)
- n = Number of payments (loan term in years × 12)

Q&A
Q: How does loan term affect my monthly payment?
A: Loan term significantly affects both your monthly payment and total interest:
Payment Impact:
- Longer Term: Lower monthly payment but higher total interest
- Shorter Term: Higher monthly payment but lower total interest
- Example: On a $200,000 loan at 5.5%:
- 30-year: $1,136/month, $208,960 total interest
- 15-year: $1,634/month, $94,120 total interest
Total Cost Impact:
- 30-year loan costs over twice as much in interest as 15-year
- But monthly payment is about $500 less
- Choose based on your budget and financial goals
Consider your income stability and other financial priorities when selecting loan term.
Q: What's the difference between fixed and adjustable rates?
A: Fixed vs. Adjustable Rate Mortgages (ARMs) differ significantly:
Fixed Rate Mortgages:
- Interest rate stays the same for the entire loan term
- Monthly payments remain consistent
- Protection against rising interest rates
- Typically higher initial rates than ARMs
- Better for long-term homeowners
Adjustable Rate Mortgages (ARMs):
- Interest rate adjusts periodically (usually annually)
- Initial rate is often lower than fixed rates
- Payment can increase or decrease with market rates
- May have rate caps limiting increases
- Better for short-term ownership plans
Popular ARM Types: 5/1 ARM (fixed for 5 years, then adjusts annually), 7/1 ARM, 10/1 ARM.
