Buying a home through a mortgage is one of the most common financial decisions worldwide. However, many borrowers do not realize how much interest they end up paying over the full loan term. Even a small increase in monthly payments can significantly reduce the total repayment time and save thousands in interest.

Formula Used in Mortgage Calculation
This calculator uses a simplified loan amortization formula to estimate repayment duration.
1. Monthly Interest Rate
r=100×12Annual Interest Rate
Where:
- r = monthly interest rate
2. Standard Loan Payoff Formula
n=−log(1+r)log(1−PL⋅r)
Where:
- n = number of months to repay loan
- L = loan amount
- P = monthly payment
- r = monthly interest rate
3. Early Repayment Formula
Early repayment assumes increased payment:Pearly=P×1.2
Then:nearly=−log(1+r)log(1−PearlyL⋅r)
4. Time Saved
Saved Months=n−nearly
5. Interest Saved
Interest Saved=(Total Standard Paid−Loan Amount)−(Total Early Paid−Loan Amount)
Example Calculation
Let’s understand with a real-life example:
- Loan Amount: $200,000
- Interest Rate: 6%
- Monthly Payment: $1,500
- Loan Term: 25 years
Results:
| Category | Result |
|---|---|
| Standard Payoff Time | ~300 months (25 years) |
| Early Payoff Time | ~240 months (20 years) |
| Time Saved | ~60 months (5 years) |
| Interest Saved | $25,000+ |
This shows how even a 20% increase in payment can significantly reduce debt burden.
