About FinancialTools
Free, accurate financial calculators for everyone.
Our Mission
FinancialTools was built on a simple premise: everyone deserves access to accurate financial tools without paywalls, signup walls, or ad-filled experiences. We believe that the math behind smart financial decisions should be free and transparent.
Our 78 calculators cover every major financial decision — from buying a home and paying off debt to planning for retirement and understanding your tax situation. Each calculator shows its formula so you can verify the math yourself.
78 Free Calculators
Covering every financial decision you'll face in life.
No Ads, Ever
We generate revenue through ethical affiliate partnerships, not ads.
Verified Formulas
Every formula is documented and verifiable. We show our work.
Education First
We explain how each calculation works, not just give you a number.
How We Sustain This
FinancialTools is free because of optional affiliate partnerships. When you click a “Recommended next step” link after using a calculator and sign up for a product, we may earn a commission at no cost to you. These partnerships never influence our calculators or editorial content.
We only recommend products we’ve researched and would use ourselves. Our calculator accuracy is never for sale.
