About SamCalculator
Last Updated: May 11, 2026
SamCalculator is a precise multi-calculators publisher founded in 2024. We build free, accurate online calculators for everyday decisions — health, finance, math, and shopping — serving a worldwide audience.
Our Mission
We believe people make better decisions when the math is transparent, honest, and instant. Most calculator websites are riddled with ads, paywalls, account requirements, and blackbox formulas. We strip that away. Every calculator on SamCalculator runs in your browser, documents its formula, cites its sources, and gives you a result in seconds — no signup, no tracking of your inputs.
Who We Serve
SamCalculator is built for a global audience. Every applicable calculator supports both Imperial and metric units, along with US dollars and other major world currencies — one click to switch. Reference data on our calculator pages often cites US authorities (CDC, NIH, USDA, IRS, S&P) because those sources publish the most rigorous, openly-available research; the underlying math, however, is universal and works wherever you live.
What We Cover
- Health — BMI, calorie, BMR, body fat, ideal weight, sleep cycles, pregnancy due date
- Finance — mortgage, loan, auto loan, retirement, compound interest, simple interest, SIP, EMI, profit margin, payment
- Math — percentage, marks percentage
- Shopping — Black Friday discount, sale price calculators
- Other — age, password generator, word counter
Editorial Standards
Every calculator is engineered against published, peer-reviewed sources — never blackbox approximations. We rely on the CDC, NIH, USDA, IRS, Federal Reserve, BLS, S&P Dow Jones Indices, the Academy of Nutrition and Dietetics, and PubMed-indexed research. Each calculator's educational section lists the exact references and last review date.

How We Make Money
SamCalculator is supported by anonymous, contextual display advertising. We do not earn affiliate commissions from any retailer, lender, broker, or financial institution mentioned on the site. We do not sell user data — there is no user data to sell, since we don't require accounts or store your inputs server-side.
Our Team
The SamCalculator Editorial Team is a small group of writers, analysts, and developers covering personal finance, consumer health, and consumer shopping. All calculator formulas, content, and references are cross-checked internally and against the published sources cited on each page.
