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.
