Investing Calculators
Free, no-signup calculators to help you plan smarter. Estimate what you will owe in federal tax, project how your investments compound over time, and understand how taxes shape your real returns. Each tool uses transparent math you can check, and links to the guides that explain the numbers behind it.

How to use these calculators together
The two tools answer different halves of the same question: how much of what you earn do you keep, and how much can it grow? Start with the income tax calculator to see your after-tax income, then feed a realistic monthly savings figure into the investment calculator to project where consistent investing could take you over 10, 20, or 30 years. The gap between contributing early and contributing late is almost always larger than people expect, and seeing it in real numbers is the best motivation to start.
Taxes and investing are deeply linked. The account you invest through — taxable brokerage, traditional 401(k)/IRA, or Roth — changes how much of your growth you actually keep. Our guides below explain those trade-offs in plain English.
