The Formula Behind the Mortgage Calculator
The monthly payment for a fixed-rate mortgage can be calculated using the standard amortization formula:M=P×(1+r)n−1r(1+r)n
Where:
- M = Monthly payment
- P = Principal loan amount (e.g., $500,000)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of monthly payments (years × 12)
If the interest rate is 0%, the formula simplifies to:M=nP
This ensures accurate calculations for all mortgage scenarios.
Example Calculation
Let’s calculate a sample 30-year mortgage for $500,000 at 6.5% annual interest:
Step 1: Convert Annual Rate to Monthly Rate6.5%÷12=0.5417%=0.005417
Step 2: Total Months30 years×12=360 months
Step 3: Apply the FormulaM=500,000×(1+0.005417)360−10.005417(1+0.005417)360
Step 4: Calculate Monthly PaymentM≈$3,160.72
Step 5: Total Payments$3,160.72×360≈$1,138,659
Step 6: Total Interest$1,138,659−$500,000≈$638,659
This example illustrates how interest can significantly increase the total cost of a mortgage over time, emphasizing the importance of understanding your loan terms.
