A clearer view of your business.

Built around everyday decisions

ProfitPilot helps small business owners, online sellers, and freelancers understand their prices, costs, and profit. Six free tools cover profit margin, target price, break-even, monthly profit, markup, and discounts.

Every tool includes its formula, a worked example, and the assumptions behind the answer. The Korean and English versions share the same calculation engine.

Your numbers stay with you

You do not need an account. Calculation inputs stay in your browser and are not submitted to a server. A temporary session in the current tab lets you carry inputs between tools and languages.

A planning tool with clear limits

These are general pre-tax estimates, not a bookkeeping system or a prediction of your business performance. Taxes, refunds, inventory timing, and financing are not automatically modeled. Check each tool’s assumptions before using a result.

The examples use illustrative figures. They explain the formulas, not typical earnings or a promise of a particular outcome.
