Extra Payment Strategy
Monthly Extra Strategy: Pay an additional amount with your regular monthly payment.
This strategy builds momentum and provides consistent principal reduction.
Yearly Extra Strategy: Make one large extra payment each year. Often from tax refunds,
bonuses, or year-end savings. This strategy is easier for budgeting irregular income.
Lump Sum Strategy: Make a one-time extra payment. Ideal for inheritance,
stock sales, or other windfalls. The earlier you make this payment, the more you save.
Custom Strategy: Combine multiple approaches for maximum impact.
Use monthly extras for consistency, yearly for bonuses, and lump sums for windfalls.

The Power of Extra Mortgage Payments
Why Extra Payments Matter: Even small extra payments can dramatically reduce your mortgage term and total interest paid. This is because extra payments reduce your principal balance immediately, which reduces the interest charged on future payments.
Key Benefits of Extra Payments:
- Compound Savings: Early extra payments have the biggest impact due to compound interest reduction
- Financial Freedom: Pay off your mortgage years earlier and eliminate a major monthly expense
- Forced Savings: Extra payments build equity faster than traditional savings accounts
- Flexibility: You can adjust or stop extra payments if your financial situation changes
Extra Payments vs Investing:
- Guaranteed Return: Extra payments give you a guaranteed return equal to your mortgage interest rate
- Risk-Free: No market risk compared to stock market investments
- Tax Considerations: Mortgage interest may be tax-deductible (consult a tax professional)
- Liquidity: Extra payments reduce liquidity - once paid, you can't easily access that money
Important Tips:
- Always specify that extra payments should be applied to principal only
- Check with your lender about any prepayment penalties
- Consider building an emergency fund before making extra payments
- Pay off higher-interest debt (credit cards) before mortgage extra payments
