Most people only discover a good calculator site when they’re already stressed — mid-way through filing taxes, comparing loan offers, or trying to remember a formula from tenth grade. YogiCalc was built to be the place you land when that happens: 197 free calculators and tools, across 15 categories, with no sign-up, no paywall, and every formula shown so you can actually check the math instead of just trusting a black box.
Here’s a full tour of what’s live right now, organized so you can bookmark the sections that matter to you.
Loans & Credit
If you’re borrowing money in any form, this is the category to start with. It covers every major loan type separately — home loan EMI, car loan, two-wheeler loan, personal loan, gold loan, business loan, education loan, and loan-against-property — plus a full credit card toolkit: interest cost, minimum-due payoff time (the eye-opening one), credit utilization ratio, and balance transfer savings. There’s also a loan comparison tool and a year-by-year amortization schedule generator.

Insurance
Insurance decisions are usually made with a sales pitch instead of math. This category fixes that: a quick Life Cover Needed rule-of-thumb calculator, a more thorough Human Life Value calculator using the DIME method, term and health insurance premium estimators, vehicle IDV and No Claim Bonus calculators, and a ULIP Charges Impact calculator that shows exactly how much fees eat into your returns over time.

Investing & Trading
Our biggest category, covering the full spread of markets: stock profit/loss and average price, mutual fund XIRR and SWP payout duration, forex pip value and lot sizing, crypto P&L and Bitcoin DCA simulation, commodity and futures margin, options breakeven and payoff, and risk-management tools like position sizing and the Kelly Criterion.

Finance & Investment
Everything about growing and managing money that isn’t a loan: compound and simple interest, SIP, fixed and recurring deposits, retirement savings, CAGR, Rule of 72, net worth, debt-to-income ratio, emergency fund sizing, and rent-vs-buy comparisons.

Tax & GST
India-specific tools (GST, TDS, TCS, HRA exemption, EPF, old vs. new income tax regime) alongside global ones (VAT, US sales tax, corporate tax), plus property and investment tax calculators — every one clearly labeled as an illustrative estimate.

Everyday, Business, Construction, Education & Automotive
Rounding things out: age and date calculators, tip and discount calculators, recipe scaling, profit margin and break-even analysis, payroll, concrete and flooring estimators, GPA and attendance calculators, and fuel efficiency and car depreciation tools.
Tools (not just calculators)
Beyond the calculators, YogiCalc now has a growing Tools section — a Word & Character Counter, Case Converter, JSON Formatter, Base64 and URL Encoder/Decoder, UUID Generator, and a SHA-256/512 Hash Generator, with more text, design, and business-document tools on the way.
Why YogiCalc shows the working
Every calculator on the site displays its formula and step-by-step math alongside the answer — not just a number. Whether you’re a student double-checking homework, a small business owner sizing up a loan, or just someone who wants to understand why a number is what it is, that’s the whole point of the site.
