Extra Payments (Loan Acceleration)
Additional principal payments beyond the required monthly amount that reduce total interest and shorten loan payoff time.
What You Need to Know
Extra payments are amounts you pay above your required monthly payment, applied directly to principal. They're the single most powerful tool to save thousands in interest and pay off loans years early—without refinancing or penalties.
How Extra Payments Work:
Every loan payment splits into:
- Interest (profit for lender)
- Principal (reduces your balance)
Early in the loan, most goes to interest. Extra payments go 100% to principal, immediately reducing the balance and future interest charges.
The Power of Extra Payments:
$300,000 mortgage at 6.5% for 30 years:
Regular payment: $1,896/month
- Total interest: $382,633
- Payoff: 30 years
Add $200/month extra:
- Total interest: $280,414
- Payoff: 22 years, 8 months
- Saved: $102,219 and 7.3 years
Add $500/month extra:
- Total interest: $212,990
- Payoff: 17 years, 5 months
- Saved: $169,643 and 12.6 years
Extra Payment Strategies:
1. Monthly Extra (Most Popular) Add fixed amount to every payment:
- $50, $100, $200, $500/month
- Easiest to automate
- Steady, predictable acceleration
2. Annual Lump Sum One big payment per year:
- Tax refund
- Work bonus
- Inheritance
3. Bi-Weekly Payments Pay half your monthly payment every 2 weeks:
- Equals 13 monthly payments per year
- Saves ~5 years on 30-year mortgage
When to Make Extra Payments:
✅ Make Extra Payments When:
- Emergency fund is full (3-6 months expenses)
- No high-interest debt (>7-8% APR)
- Not missing 401(k) match
- Mortgage/loan rate > 5%
❌ Don't Make Extra Payments If:
- You have credit card debt (pay that first!)
- No emergency fund (build this first)
- Missing 401(k) match (free money!)
- Mortgage rate < 4% (invest surplus instead)
Important: Always specify "apply to principal" or lender may apply to future interest.
The Bottom Line: Extra payments are a guaranteed, risk-free return equal to your interest rate. Even $50/month makes a massive difference over time. The key is starting early—Year 1 extra payments have 10x the impact of Year 15 payments.
