The Formula Behind the Calculator
The mortgage calculator uses the amortization formula to calculate monthly payments:Monthly Payment=1−(1+r)−nP⋅r
Where:
- P = Loan amount (Principal)
- r = Monthly interest rate (annual interest rate ÷ 12 ÷ 100)
- n = Total number of monthly payments (Loan term in years × 12)
Once the monthly payment is calculated:
- Total Payment = Monthly Payment × Total Months
- Total Interest = Total Payment − Loan Amount
This formula accounts for both the principal and interest paid over the loan term.
Example Calculation
Let’s assume the following for a $900,000 mortgage:
- Loan Amount: $900,000
- Annual Interest Rate: 6%
- Loan Term: 30 years
Step 1: Convert annual interest to monthly rater=1006÷12=0.005
Step 2: Total number of paymentsn=30×12=360 months
Step 3: Calculate monthly paymentMonthly Payment=1−(1+0.005)−360900,000⋅0.005 Monthly Payment≈5,398.95 USD
Step 4: Calculate total paymentTotal Payment=5,398.95×360≈1,943,622USD
Step 5: Calculate total interestTotal Interest=1,943,622−900,000≈1,043,622USD
So, over 30 years, a $900,000 mortgage at 6% interest would cost approximately $5,399 per month, with $1,043,622 in total interest.
