Free Financial Calculators for Every Money Decision

QuantCurb provides over 40 free financial calculators to help you make smarter money decisions. Whether you're calculating your take-home pay, planning for retirement, figuring out how much house you can afford, or comparing loan offers, our tools give you accurate, personalized results in seconds.

Salary & Tax Calculators

Our salary calculator shows your exact take-home pay after federal tax, state tax, FICA, and 401(k) deductions for all 50 US states. See your paycheck breakdown for weekly, biweekly, semi-monthly, or monthly pay periods. Freelancers can use our 1099 tax calculator to estimate self-employment tax, quarterly estimated payments, and compare contractor income to W-2 salary equivalents.

Mortgage & Home Buying Tools

The mortgage payment calculator gives you a complete PITI breakdown: principal, interest, property taxes, and homeowners insurance. See when PMI drops off based on your loan-to-value ratio, compare 15-year vs 30-year mortgages, and calculate how biweekly payments save you thousands in interest. Our debt-to-income calculator tells you if you'll qualify for a mortgage based on lender DTI requirements.

Retirement & FIRE Planning

Calculate your FIRE number (Financial Independence, Retire Early) using the 4% rule, 3% rule, or custom withdrawal rates. Compare Lean FIRE, Fat FIRE, Coast FIRE, and Barista FIRE scenarios. Our 401(k) and IRA calculator helps you optimize contributions, compare Roth vs Traditional accounts, and project your retirement balance with employer matching and compound growth.

Investment & Wealth Building

See how your investments grow over time with our compound interest calculator. Model monthly SIP contributions, lump sum investments, and dividend reinvestment (DRIP) scenarios. For advanced investors, the DCF calculator lets you value stocks using discounted cash flow analysis with WACC, and the options strategy visualizer helps you build multi-leg strategies with real-time Greeks.

Debt Payoff Strategies

Find the fastest way to become debt-free with our credit card payoff calculator. Compare the avalanche method (highest interest first) vs the snowball method (smallest balance first) and see exactly how much interest you'll save. Our loan comparison tool lets you evaluate refinancing offers side by side with break-even analysis.

Frequently Asked Questions

Are these financial calculators really free?โ–ผ
Yes, all 40+ calculators on QuantCurb are completely free with no account required. There are no hidden fees, no premium tiers, and no usage limits. We cover salary, mortgage, retirement, investment, tax, and debt calculators.
How accurate are the tax calculations?โ–ผ
Our calculators use 2025 federal tax brackets, FICA rates, and state tax data for all 50 US states plus DC. They account for standard deductions, 401(k) contributions, and common pre-tax benefits. For complex tax situations, consult a CPA.
What is the 4% rule for retirement?โ–ผ
The 4% rule suggests you can safely withdraw 4% of your retirement portfolio each year without running out of money over a 30-year retirement. To find your FIRE number, divide your annual expenses by 0.04. For example, if you spend $40,000/year, your FIRE number is $1,000,000.
How much emergency fund should I have?โ–ผ
Most financial experts recommend 3-6 months of essential living expenses. If you have variable income (freelance, commission-based), unstable employment, or dependents, aim for 6-12 months. Our emergency fund calculator gives you a personalized recommendation.
How do I calculate my debt-to-income ratio?โ–ผ
Divide your total monthly debt payments (mortgage, car loan, credit cards, student loans) by your gross monthly income. Multiply by 100 for a percentage. Most mortgage lenders require a DTI below 43%, with ideal ratios under 36%.
