Key Assumptions:

• Target replacement ratio is 60-70% of pre-disability gross income to maintain essential living expenses

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.

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.
