FinCalc Free finance calculators

Free, editorial-grade finance calculators — built for real money decisions.

FinCalc is a hand-built collection of 60+ free financial calculators covering mortgages, loans, income tax, retirement planning, debt payoff, and everyday money math. Every calculator runs entirely in your browser — we do not collect your inputs, require sign-ups, or share data with lenders or third parties.

The site is operated by Hi Tex Lawn Pro LLC, with editorial content written by Vince P. and Jean P. and reviewed annually for accuracy against current IRS, HUD, VA, and Department of Education guidance. Our goal is calculators that are accurate, transparent, and plain-spoken — without the lead-generation games that dominate the personal-finance category.


Mortgage & home buying

A mortgage is the biggest financial commitment most households ever sign. Our mortgage suite goes well beyond a generic monthly-payment calculator: we compute true affordability based on DTI ratio limits (28/36 standard, 31/43 FHA, 41/41 VA), model private mortgage insurance triggers, factor in property tax and homeowners insurance based on real state averages, and project amortization schedules with extra-payment scenarios that can save tens of thousands over a 30-year loan.

Tax calculators

Federal tax law changed materially under the 2025 One Big Beautiful Bill Act (OBBBA), introducing "no tax on overtime" and "no tax on tips" above-the-line deductions, and shifting standard deduction amounts. Our tax suite reflects the 2025 brackets, the new OBBBA deductions with MAGI phaseouts, and 50 state-specific income tax calculators using current state department of revenue data.

Retirement & investment

The largest single financial decision after a home purchase is how and where you save for retirement. Our retirement suite focuses on giving you the comparison you actually need to make: Roth versus Traditional, employer-match capture, the long-horizon power of compound interest, and the side-by-side of investment vehicles.

Debt & loan calculators

For households carrying revolving balances, the choice of payoff strategy matters more than most people realize. The avalanche method (highest-rate first) saves the most money mathematically; the snowball method (smallest balance first) wins on behavioral follow-through. Both are valid — our calculators give you the side-by-side so you can pick the one you'll actually stick with.

The small everyday decisions that nobody else writes calculators for: tipping math, rent vs buy at your actual income, salary breakdowns, and savings goals.

Editorial standards & how we make money

FinCalc is supported by display advertising — Google AdSense ads appear in clearly labeled placements throughout the site. We do not place referral links to lenders, we do not sell leads, and we do not steer calculations toward products that pay us commissions. Every calculator returns the same answer regardless of who you are or what ads happen to be served. Our editorial mission is straightforward: give households the same financial-math clarity a financial advisor would charge for, without charging for it.

Calculator math is sourced from primary documents: IRS tax brackets and deduction tables, HUD loan limits, VA funding fee schedules, Department of Education student loan terms, and Social Security wage base figures. We update the calculators when rules change (typically January 1 each year, and any time Congress passes mid-year tax legislation like the OBBBA in 2025).

Contributors: Vince P. (calculator logic, tax content, mortgage analysis) and Jean P. (editorial review, retirement planning content). Both contribute under Hi Tex Lawn Pro LLC, the operating company behind FinCalc.
