Under the Hood: Key Formulas
Though our tool handles the math, here’s what’s happening behind the scenes:
1. Monthly Payment (Amortized Loan)
iniCopyEditM = P × r × (1 + r)^n / [(1 + r)^n − 1] - M: Monthly payment
- P: Principal (loan amount)
- r: Monthly interest (annual rate ÷ 12 ÷ 100)
- n: Total payments (years × 12)
2. Total Interest Paid
javaCopyEditTotal Interest = M × n − P 3. Interest Savings
iniCopyEditSavings = Total Interest_Current − Total Interest_New 4. Break-Even Point
mathematicaCopyEditBreak‑Even (months) = Closing Costs ÷ Monthly Savings Real-World Example
Let’s illustrate with a typical scenario:
Inputs
| Parameter | Value |
|---|---|
| Current Balance | $250,000 |
| Current Rate | 5.25% |
| Remaining Term | 20 years |
| New Rate | 3.75% |
| New Term | 20 years |
| Closing Costs | $4,500 |
Calculation Results
- Current Monthly Payment: Calculated via formula above
- New Monthly Payment: Approximately $1,469
- Monthly Savings: Roughly $370
- Total Interest Saved: Over $88,800 across the term
- Break-Even: Around 12–13 months to recover costs
Takeaway:
By refinancing from 5.25% to 3.75%, you could save nearly $370 each month and recover your closing costs in just over a year. Over 20 years, this translates to close to $90K in interest savings!
