  • Not financial advice—verify big decisions with professionals

Scope: Exploration only—not a substitute for licensed guidance.

Bookmark for quick what-if checks—still confirm big decisions with professionals.

What Is This Tool?

Markup vs. margin from cost and price—keep retail formulas consistent. Educational estimates—not financial, tax, or legal advice.

Why Use This Tool?

Model payments, growth, and margins before you open a spreadsheet or call a lender. You keep control of every assumption—then verify with official quotes, tax law, and licensed advisors.

When to Use It

Pricing decks, founder dashboards, and quick feasibility before you involve Finance.

How It Works

  1. Enter revenue, costs, units, or cash-flow rows the tool requests.
  2. Calculate—margin %, breakeven units, NPV, IRR, or payback appears.
  3. Document assumptions (growth, discount rate) for stakeholders.
  4. Reconcile to accounting software before board decisions.

Features

  • Instant estimates after valid inputs
  • No bank linking required
  • No sign-up
  • Runs locally in your browser session
  • Copy-friendly numbers for spreadsheets
  • Free for personal and small-business what-if work

Understanding the Results

What it means: Margins and NPV summarize your typed assumptions—garbage in, garbage out.

What to do next: Tie discount rates to your cost of capital; sync units with your accounting system.

Best Practices

Next: compare loan payment, compound growth, and budget planning. Browse all tools.

Privacy: Dollar amounts you type stay in this browser. We do not receive your financial data on our servers for these calculators.

FAQ

  • Will my bank match this payment? Maybe—APR, fees, compounding, and day-count conventions differ; use official disclosures.
  • Do I need an account? No—free without registration.
  • Are tax results official? No—rates and brackets change; use IRS or local guidance and a CPA when it counts.
  • Investment guarantees? None—past performance does not predict future returns.
  • Mobile? Yes—plan on the go, then document on desktop.
