Tips for Maximizing Savings

1. Start Early

Extra payments made earlier save more interest due to compounding.

2. Use Windfalls

Apply bonuses, tax refunds, or gifts as extra payments.

3. Increase Gradually

Even small yearly increases can have a big impact.

4. Round Up Payments

Rounding up to the nearest hundred accelerates repayment.

5. Check Prepayment Penalties

Always confirm your lender allows extra payments without fees.

Why Extra Payments Matter

Many borrowers underestimate how interest accumulates over time. A 30-year loan may cost nearly double the borrowed amount due to interest. Extra payments reduce the principal faster, which lowers future interest calculations.

This creates a snowball effect:

• Lower principal
• Less interest
• Faster payoff

The calculator makes this concept easy to visualize.

You should use the Additional Payment Calculator if you:
