Mortgage Calculation Formula Explained
The calculator uses a standard mortgage amortization formula to determine monthly payments:
Monthly Payment Formula:
M=1−(1+r)−nP×r
Where:
- M = Monthly payment
- P = Loan principal (loan amount)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (years × 12)
How It Works in Simple Terms
- The loan amount is divided across all months.
- Interest is added monthly based on remaining balance.
- Payments remain fixed, but interest portion decreases over time.
- Principal repayment increases gradually.
This method ensures the loan is fully paid by the end of the term.
Example of Mortgage Calculation
Let’s understand with a real-life example:
- Loan Amount: $200,000
- Annual Interest Rate: 6%
- Loan Term: 20 years
Step-by-step result:
- Monthly Interest Rate = 0.06 ÷ 12 = 0.005
- Loan Term = 20 × 12 = 240 months
Results:
- Monthly Payment ≈ $1,432.86
- Total Payment ≈ $343,886.40
- Total Interest ≈ $143,886.40
This shows how much extra you pay over the original loan amount due to interest.
