The Power of Extra Payments

Making extra payments on your loan is one of the most effective ways to save money and become debt-free faster. Even small additional amounts can make a dramatic difference over time.

Why It Works

Extra payments go directly toward principal, reducing the balance that accrues interest. This creates a snowball effect — less balance means less interest, which means more of each payment goes to principal.

How Extra Payments Save Money

Consider a $15,000 loan at 18.99% APR with a $400 monthly payment:

Double Impact

Extra payments save you money twice: you pay less interest AND you're debt-free sooner!

Strategies for Faster Payoff

1. Round Up Payments

If your minimum is $387, round up to $400 or even $450. The small difference adds up significantly over time.

2. Bi-Weekly Payments

Instead of 12 monthly payments, make 26 half-payments. This results in one extra full payment per year without feeling the pinch.

3. Lump Sum Windfalls

Apply tax refunds, bonuses, or gifts directly to your loan principal. A single $1,000 windfall can save hundreds in interest.

4. Debt Avalanche Method

If you have multiple debts, focus extra payments on the highest-interest debt first. This mathematically minimizes total interest paid.

Interest Cost Over Time

High-interest debt like credit cards can cost you more in interest than the original purchase. Here's how interest rates affect total cost:

APRInterest on $10K (5 years)Total Paid
6%$1,600$11,600
12%$3,346$13,346
18%$5,231$15,231
24%$7,272$17,272

warning

Credit Card Trap

At 24% APR, you'd pay more than 70% extra in interest! Prioritize paying off high-interest debt first.

The Minimum Payment Trap

Credit card companies love minimum payments because they maximize their profit. A $5,000 balance at 20% APR with 2% minimum payments takes over 30 years to pay off!

  • Minimum payments are designed to keep you in debt longer
  • Most of your minimum payment goes to interest, not principal
  • Always pay more than the minimum when possible
  • Even $20 extra per month makes a significant difference

Frequently Asked Questions

Q: Is there a penalty for paying off loans early?

A: Most consumer loans (credit cards, personal loans, auto loans) have no prepayment penalty. Mortgages sometimes do in the first few years — check your terms.

Q: Should I pay extra or invest the money instead?

A: If your loan rate is higher than expected investment returns (after taxes), pay off the debt. For low-rate debt (under 5%), investing may be better mathematically.

Q: How do I specify extra payments go to principal?

A: Contact your lender to ensure extra payments are applied to principal, not future payments. Most online systems have an option for this.

Q: Should I pay off smallest debt or highest interest first?

A: Mathematically, highest interest (Avalanche) saves more money. Psychologically, smallest balance (Snowball) provides quick wins. Both work — pick what motivates you.

Q: What if I can't afford extra payments?

A: Even $10-20 extra helps. Look for ways to cut small expenses, or apply any unexpected money (like rebates or gifts) to your debt.
