About TradeProfitCalculator

TradeProfitCalculator is a free suite of 7 trading calculators for stocks, crypto and futures — profit/loss, position size, risk/reward, stop loss & take profit, target price, break-even and average down. Every tool runs entirely in your browser, updates live as you type, and works without a sign-up.

Why it exists

Most trading calculators online are slow, cluttered with intrusive ads, or quietly wrong — many ignore commissions, which overstates your real returns. TradeProfitCalculator was built to be the opposite: fast, clean, and accurate, with fees included so the numbers match what actually hits your account.

How we keep the math right

Accuracy is the whole point of a finance tool. Every calculator's logic lives in a small, framework-free module that is covered by an automated test suite — dozens of unit tests checking edge cases like zero and negative inputs, fractional crypto amounts, large numbers, fees that exceed gains, long versus short positions, and division-by-zero guards. We verify each tool against hand-calculated values before it ships.

Privacy by design

The site is a static export served from a CDN — there's no server logging your inputs. The numbers you type never leave your device. See our Privacy Policy for details.

Who builds it

TradeProfitCalculator is an independent project by Vaibhav Kamble, a software engineer with 15+ years of experience building software, with a personal interest in markets and trading. The site is kept free and supported by light, non-intrusive advertising and the occasional disclosed broker affiliate link — neither of which ever affects the calculator results.

Important
