About this site

Free calculators built by a working appraiser and broker — not a content farm

The Handy Calculators is a small, independent site with one job: give you the exact number you came for, then explain how it was calculated so you can trust it.

Every tool on this site is hand-built around a real decision — a mortgage you're weighing, a paycheck you're negotiating, a training plan you're starting, a deadline you're counting down to. The formulas come from primary sources: IRS publications for take-home pay, the Mifflin-St Jeor equation for calories, Fannie Mae and Freddie Mac amortization conventions for mortgages, ASHRAE and building-code references for home projects, and peer-reviewed research for the health estimators. When a calculator uses an assumption you can override — a tax bracket, a discount rate, a maintenance reserve — you'll see the assumption spelled out, not buried.

Nothing here is auto-generated fluff. Each page is written and reviewed by a human, tested against worked examples, and updated when the underlying rates, brackets, or standards change. There are no popups, no email walls, no dark-pattern upsells, and the site runs entirely in your browser — none of your inputs leave your device.

Sourced, not scraped

Formulas cite IRS, Fannie Mae, ASHRAE, ACSM, and peer-reviewed research — not other calculator sites.

Worked-example tested

Every tool is checked against at least one manually-worked example before it ships, and re-tested when rates change.

Private by default

Calculations run entirely in your browser. No accounts, no data collection on inputs, no results sent anywhere.

Real-life scenarios

Built for the decisions you actually make

TheHandyCalculators.com isn't a math reference — it's a decision toolkit. Every calculator is designed around a real situation people face at home, at work, at school, or on the move. Here are a few of the moments our tools were built for.

Buying or refinancing a home

Compare a 30-year vs 15-year mortgage, see exactly how much a 1% rate cut saves over the life of the loan, find your break-even on a refinance, and budget for closing costs before you sign anything.

Negotiating a job offer

Translate a salary offer into real take-home pay by state, compare an hourly contract to a salaried role, and stress-test whether a relocation makes sense after taxes, cost of living, and benefits.

Getting healthier this year

Find your daily calorie target with Mifflin-St Jeor TDEE, dial in a sustainable deficit, track BMI and body-fat trends, and build a training plan around heart-rate zones and realistic running pace.

Surviving finals week

Calculate your current GPA, weight every assignment by syllabus category, and find the exact score you need on the final to lock in the grade you want — without guessing or scrolling through Reddit threads.

Underwriting a real-estate deal

Run cap rate, cash-on-cash, DSCR, and full multifamily, hotel, retail, office, or industrial proformas in seconds — the same math brokers and analysts use, without an Excel template or a paid platform.

Planning a trip or a project

Count business days until a deadline, line up meetings across time zones with full DST handling, convert recipes from cups to grams, or estimate concrete, paint, and tile before a weekend renovation.

Why people keep coming back

Fast answers, trustworthy math, no friction

We obsess over two things: the accuracy of the underlying formulas and how quickly you can get a useful number out of them. Everything else — sign-ups, paywalls, dark patterns — gets cut.

Instant results in your browser

Every calculation runs locally the moment you type — no loading spinners, no server round-trips, no waiting. Most pages give you an answer in under a second on a phone over 4G.

Research-backed formulas

We use the same formulas trusted by clinicians, lenders, and analysts — Mifflin-St Jeor for TDEE, fully amortizing loan math, NOI / cap-rate for real estate, IRS-aligned tax tables, and unit conversions to international standards.

Your inputs stay private

Numbers you type — salary, weight, loan balance, health metrics — are processed in your browser and never sent to a server. There's no account, no tracking pixel tied to your answers, and no email gate.

Built for the whole web

Available in English, Spanish, Portuguese, and German, with metric and US units side by side, mobile-first layouts, and copy-friendly results that paste cleanly into email, Slack, or a spreadsheet.
