Calculators

Free tools with live graphs. The 2026 paycheck calculator uses IRS brackets and a W-4 extra-withholding suggestion. The 529 vs taxable calculator is free (hash + bars). Playbooks still sit behind PayPal.

Quick answer: These calculators run in the browser and update as you type. Each full tool has its own page with a shareable link, a breakdown, and the assumptions for that topic. The samples are examples so the page is not blank.

What this means for you

What this means for you: start with the question you actually have — a paycheck, a housing payment, a debt, or a savings target — and open that tool. The tabs here are the same classroom math as the standalone pages. They are educational estimates, not a filing, a loan approval, or an investment recommendation.

  1. Open the Personal finance calculators and keep the sample numbers or replace them with your own. The result updates as you type.
  2. Read the headline figure first, then the breakdown or chart under it.
  3. Use Copy share link if you want those inputs in the URL. The page is an educational estimate, not a filing, approval, or recommendation.
