Understanding the Mortgage Payoff Formula
This calculator is based on the standard loan amortization formula used in financial mathematics.
Monthly Interest Rate
The annual interest rate is converted into a monthly rate:r=100×12Annual Interest Rate
Mortgage Payoff Time Formula
The number of months required to pay off a loan is calculated using:
n=ln(1+r)ln(P−rLP)
Where:
- n = number of months to repay the loan
- P = monthly payment
- L = loan amount (principal)
- r = monthly interest rate
Total Payment Formula
Total Payment=n×P
Total Interest Formula
Total Interest=Total Payment−Principal
How the Calculator Works (Concept Explained)
This tool uses the amortization principle, which means each monthly payment covers:
- Interest portion (based on remaining balance)
- Principal portion (reducing loan balance)
At the beginning of the loan, most of your payment goes toward interest. Over time, more goes toward reducing the principal. The calculator simulates this financial behavior mathematically to estimate total repayment time.
Example Calculation
Let’s understand with a real-life example:
Loan Details:
- Loan Amount: $200,000
- Annual Interest Rate: 6%
- Monthly Payment: $1,500
Step-by-step result:
- Monthly interest rate = 0.06 / 12 = 0.005
- Payoff time ≈ 186 months (approx. 15.5 years)
- Total payment ≈ $279,000
- Total interest ≈ $79,000
Summary Table Example
| Loan Amount | Interest Rate | Monthly Payment | Payoff Time | Total Interest |
|---|---|---|---|---|
| $150,000 | 5% | $1,200 | 14.2 years | $52,000 |
| $200,000 | 6% | $1,500 | 15.5 years | $79,000 |
| $300,000 | 7% | $2,000 | 16.8 years | $145,000 |
