Calculates your current home equity by subtracting the remaining mortgage balance from the estimated current market value. Projects future equity growth based on home appreciation rate and mortgage principal paydown schedule.

Data Sources:

• S&P CoreLogic Case-Shiller Home Price Index for historical appreciation rates
• Federal Housing Finance Agency (FHFA) House Price Index by metro area
• Freddie Mac amortization schedules for principal paydown projections

Key Assumptions:

• Home appreciation is projected at a constant annual rate; actual appreciation varies year to year
• Mortgage balance reduction follows the standard amortization schedule with no extra payments
• Current market value is an estimate; a professional appraisal provides the most accurate figure

Market Conditions

Time Horizon

Longer time horizons amplify the effect of compound interest and rate changes. Even small rate differences compound into significant dollar amounts over years.

After you run the calculator, your results include interactive sections that help you make informed decisions:

Financial Breakdown

Your results separate principal from interest (or contributions from earnings) so you can see exactly how your money is working. Understanding this split helps you evaluate whether refinancing, extra payments, or alternative strategies could save you money over time.

Visual Chart

Charts make it easy to grasp the relationship between what you pay and what you owe (or what you save and what you earn). A quick look at the visual split helps you decide whether your current approach is on track or whether adjustments to your payment or contribution strategy could improve your outcome.

Payment or Growth Schedule

The schedule shows how your balance changes period by period — whether that is a loan being paid down or savings growing over time. Each row shows the split between principal and interest (or contributions and earnings), so you can see exactly when you cross key milestones. This long-range view helps you plan major financial decisions with confidence rather than guesswork.

Here are proven strategies to reduce your costs:

1. Compare Rates from Multiple Lenders: Shop rates from at least 3 lenders. Even a 0.25% difference in interest rate can save thousands over time.
2. Automate Your Savings: Set up automatic transfers to savings or investment accounts. Consistent contributions compound significantly over time.
3. Maximize Tax-Advantaged Accounts: Contribute to 401(k) up to employer match, then fund IRA/Roth IRA. Tax-advantaged growth accelerates your returns.
4. Reduce High-Interest Debt First: Pay off credit cards and high-APR loans before investing. Eliminating 18-25% APR debt is a guaranteed return.
5. Review Fees and Expense Ratios: High fund fees erode returns. Index funds with 0.03-0.10% expense ratios outperform most actively managed funds over time.
6. Use Balance Transfer Offers Strategically: 0% APR balance transfer offers can save hundreds in interest — but pay off before the promotional period ends.
