About Calculators With Steps

Calculators With Steps is an independent website that offers 88 free online calculators for personal finance, Indian tax and investments, health and fitness, math, dates and everyday tasks. We started in 2025 with a simple goal: a calculator should give you a correct answer and also show how it got there. The site was previously called Calculate Everything (calculate-everything.in) and moved to calculatorswithsteps.com in November 2026.

What makes our calculators different

• Transparent formulas. Every calculator page explains the formula it uses, with a worked example you can check by hand.
• Private by design. Calculations run in your browser. We do not receive, log or store the numbers you type.
• Built for the US and India. General tools support several currencies, and country-specific tools say which rules and tax year they follow.
• Fast and accessible. Pages are lightweight, work on any phone, support dark mode and keyboard navigation, and need no sign-up.

How we build and check each calculator

1. Primary sources first. We base each calculator on a published, widely accepted method: the standard amortization and compound-interest formulas for money, IRS revenue procedures for U.S. federal tax, the Income Tax Department and Union Budget for Indian tax, and published equations such as Mifflin-St Jeor and the U.S. Navy body-fat formula for health. Sources are listed at the bottom of each page.
2. Automated tests. Every calculator's logic runs against test cases with known answers before each release, for example confirming that a $320,000, 30-year loan at 6.5% gives a payment of $2,022.62.
3. Plain-language explanations. We explain the inputs, the formula, how to read the result and its limitations, including when you should talk to a professional instead.
4. Regular updates. Tax brackets, contribution limits and statutory rates change every year. Pages that depend on them show the tax year they use and a "last updated" date.

How our articles are written

The explanations on each calculator page are drafted with the help of AI writing tools and then edited and fact-checked against the primary sources listed on that page. We don't publish a figure we haven't checked: every number in a worked example or FAQ is produced by the calculator itself and confirmed by an automated test, and statutory figures such as tax slabs, contribution limits and interest rates are taken from the official documents cited.

Corrections

If you spot an error, an outdated rate or a confusing explanation, please contact us. We check every report and update the page, and its "last updated" date, when a correction is needed.
