What it does

Add income and expense lines and see cash flow monthly, quarterly, and annually. A negative line or month turns red so you can spot shortfalls early. Works for personal finance, freelance months, or a small side business.

Pair with startup runway calculator, budget calculator, and profit margin calculator.

How to use it

  1. Add each income line with its monthly amount.
  2. Add each expense line the same way.
  3. Read monthly, quarterly, and annual totals.
  4. Trim expenses or boost income until cash flow is positive.
