Calculators built for people who want the numbers, not the noise
MarketCalc.com started with a simple frustration: most financial calculators online are either buried in ads, missing the formula behind the result, or built for one narrow use case. We wanted something faster and more transparent — tools that show you the working, not just a final number you have to trust blindly.
Today, MarketCalc offers free calculators covering crypto profit and loss, stock averaging, portfolio rebalancing, price change, market cap, and holding period return. Every tool is built around the same principle: enter your numbers, see an instant result, and understand exactly how that result was calculated.
What We Believe In
Show the formula. Every calculator on MarketCalc is built around a real, documented financial formula — not a black box. We’d rather you understand the math than just trust our output.
No sign-up, no clutter. You shouldn’t need an account to divide two numbers. Every tool on this site works instantly, with no login and no personal data required.
Built for real use cases. Our calculators are shaped by the actual questions investors, traders, and students ask — from “what’s my true average buy price?” to “how much do I need to sell to hit my target allocation?” We prioritize the tools people actually reach for over ones that just look good in a menu.
Accuracy first. We test our calculators against known formulas and worked examples before publishing them, and we keep updating them as we get feedback.
Who Uses MarketCalc
Our tools are used by everyday investors tracking their own portfolios, active traders checking crypto and stock positions, finance students learning core formulas, and analysts who just want a fast, reliable second check on their math.
A Note on What We’re Not
MarketCalc.com is an independent calculator and information resource. We are not a brokerage, financial advisory firm, or registered investment advisor, and nothing on this site should be taken as personalized financial advice. Our tools are built to help you do the math — the decisions are always yours, and we’d encourage speaking with a qualified professional for anything that affects your actual finances.
