Our Mission
CalculWise exists to make financial, health, and tax calculations accessible to everyone — for free. We believe no one should have to pay for a basic mortgage estimate or struggle with confusing tax bracket math. Our tools are designed to give you instant, accurate answers so you can make informed decisions about your money, health, and future.
We are not a financial advisory firm. We do not sell financial products or insurance. We have no partnerships that bias our calculations. Our only goal is accuracy and clarity.
How Our Calculators Work
For a detailed look at our research process, formula sources, testing methodology, and update schedule, see our How We Build Our Calculators page.
Every calculator on CalculWise is built on industry-standard formulas verified against authoritative sources:
- Financial calculators use standard amortization, compound interest, and present value formulas. Our mortgage calculator follows the same methodology used by the Consumer Financial Protection Bureau.
- Tax calculators are updated annually to reflect current IRS tax brackets, standard deductions, and FICA rates. State tax data is sourced from each state's Department of Revenue.
- Health calculators use peer-reviewed formulas. Our BMI calculator follows WHO classification standards. Our calorie and macro calculators use the Mifflin-St Jeor equation, recognized by the American Dietetic Association as the most accurate for estimating BMR.
- Insurance calculators provide estimates based on industry averages from the National Association of Insurance Commissioners and are not quotes from any specific insurer.
All calculations happen instantly in your browser — we never store your inputs or personal data.
Our Editorial Standards
Every article and guide on CalculWise follows strict editorial standards:
- Fact-checked: All claims cite primary sources — government agencies (IRS, SSA, CDC, CFPB), peer-reviewed research, or official industry data.
- No AI-only content: While we use AI tools to assist with research and drafting, every article is reviewed, edited, and verified by our team for accuracy and completeness.
- Updated regularly: Tax rates, contribution limits, and health guidelines change annually. We update our content and calculators to reflect current data.
- No conflicts of interest: We do not accept payment to recommend specific products, services, or providers. Our content is independent.
