Mortgage, retirement, investing, taxes, debt payoff, and 95+ more financial tools — all free.
99 free calculators · No signup required
This is the section of the site I built first — and the one I still use the most. Loans, mortgages, investments, taxes, retirement projections, debt payoff strategies. Each tool lets you model different scenarios with your actual numbers so you can see what a decision really costs before you commit.
I've found that most financial anxiety comes from not running the math. Once you see the numbers laid out — how an extra $200/month changes your mortgage payoff, what starting a Roth five years earlier actually means — the decision usually gets a lot clearer. Every calculator here is free, requires no signup, and shows step-by-step breakdowns so you understand exactly how your results work.
These tools cover every angle of home financing. I'd start with the Mortgage Calculator for payment estimates, then run your numbers through Home Affordability to see what you can realistically handle. The gap between those two numbers is where most buyers get in trouble.
Tools for compound growth, 401(k) analysis, Roth IRA projections, and Social Security estimates. I can't stress this enough: the single biggest variable in retirement math is when you start. Even small amounts early beat large amounts late, and these tools make that painfully clear.
Compare payoff strategies, calculate loan payments, and find the fastest path out of debt. The Debt Payoff Comparison tool is one of my favorites on the site — it shows snowball vs. avalanche side by side so you can stop arguing about which method is better and just see the math.
Estimate your taxes, compare W-2 vs. 1099 income, calculate take-home pay, and plan tax-efficient strategies. The 1099 vs. W-2 calculator alone has saved a lot of freelancers from an ugly surprise in April.
Emergency fund planning, budgeting, and savings goal tracking. Straightforward tools, but the kind of thing most people put off until they actually see how far behind (or ahead) they are.
