Slash Your Interest Costs

The most effective way to save money on a mortgage is to pay extra toward the principal. This reduces the balance on which interest is calculated, creating a compounding savings effect.

Why It Works

1. Compounding Savings: Every dollar of principal removed today stops generating interest for the rest of the loan term. 2. Term Reduction: Adding just one extra payment per year can often shave 4-5 years off a 30-year mortgage. 3. Pure Equity: Extra payments go 100% toward equity, not interest.

🚀 The Power of $200

On a $300,000 mortgage at 7%, adding just $200 extra per month can save you over $100,000 in interest** and pay the house off **8 years earlier.

Frequently Asked Questions

Q: Is there a penalty for extra payments? A: Most modern mortgages allow "prepayment" without penalty, but always check with your lender if you have a "Prepayment Penalty" clause.

Q: Should I pay off my mortgage or invest? A: If your mortgage rate is 3%, you might be better off investing. If your rate is 7%+, paying it off is a guaranteed "return" of 7%, which is hard to beat after taxes.
