About HanCalc
We built HanCalc because everyone deserves access to fast, free, and accurate calculators — whether you're planning a mortgage, tracking fitness goals, or just doing everyday math.
Who We Are
HanCalc is a free online calculator hub designed for real people — students, professionals, parents, and anyone who needs reliable numbers fast. We offer 50+ calculators across finance, health, math, and utility categories, all available instantly with no login, no fees, and no hassle.
Our team is passionate about making financial and mathematical tools accessible to everyone. We believe that understanding your numbers — whether it's your loan payment, your BMI, or your Zakat — is a fundamental right, not a privilege reserved for those who can afford professional software.
Our Mission
To simplify complex calculations and empower people to make smarter financial, health, and everyday decisions — completely free of charge.
Every calculator on HanCalc is built with three goals in mind: it must be easy to use, instantly accurate, and genuinely useful in real life.
"Fast, accurate, and always free — that's not just our tagline, it's our commitment to every person who visits HanCalc."
What We Stand For
Everything we build at HanCalc is guided by four core values:
Speed
Results in milliseconds. No loading screens, no waiting — just instant answers.
Accuracy
Every formula is verified. You can trust HanCalc results for real decisions.
Free Forever
No subscriptions, no paywalls. All calculators are and will always be free.
Privacy First
We don't store your inputs. Your financial and health data stays on your device.
What HanCalc Offers
Financial Calculators — From mortgage payments and loan comparisons to compound interest, investment returns, and income tax estimates.
Fitness & Health Calculators — BMI, BMR, calorie intake, body fat percentage, ideal weight, and pregnancy tracking.
Math Calculators — Scientific calculations, fractions, percentages, standard deviation, triangle geometry, and more.

A Tool Built With Purpose
One of the things we're most proud of is our Zakat Calculator. Calculating Zakat accurately is an obligation for millions of Muslims worldwide, yet reliable free tools are rare. HanCalc's Zakat Calculator helps you determine your eligible assets, apply the correct Nisab threshold, and calculate the 2.5% due — with clarity and confidence.
