How Extra Principal Payments Save You Money
All standard amortizing consumer loans (mortgages, auto loans, student loans, and personal loans) split your monthly payment between interest charges and principal reduction. The interest is computed monthly based on your remaining principal balance:
When you make an extra payment, 100% of that extra contribution goes directly toward reducing your principal balance, bypassing the interest split. This reduces the balance faster, which in turn reduces the interest charged in all following months. For consumer guidelines on loan repayment options, review the resources on the Consumer Financial Protection Bureau (CFPB).
Worked Numerical Example
Consider a standard loan of $250,000 at a 6.5% interest rate over a 30-year term, with an extra payment of $200/month:
- Remaining Loan Balance: $250,000
- Interest Rate: 6.5% (APR)
- Original Term: 30 Years (360 Months)
- Standard Monthly Payment: $1,580.17
- Extra Monthly Payment: $200.00
| Payoff Option | Monthly payment | Total Interest Paid | Total Cost of Loan | Payoff Timeline |
|---|---|---|---|---|
| Standard Schedule | $1,580.17 | $318,861.12 | $568,861.12 | 30.0 Years |
| Accelerated Prepayment | $1,780.17 | $238,122.12 | $488,122.12 | 23.8 Years |
| Total Savings | +$200.00 / month | $80,739.00 Saved | $80,739.00 Saved | 6.2 Years Shaved Off |
