How to Create a Simple ROI Calculator

An ROI calculator shows prospects exactly how much they'll save or gain with your product. It turns abstract value into concrete numbers—and speeds up decisions. Here's how to build one that works.

Purpose

**Show prospects their return** — "If you use our product, you'll save $X per year." Make it concrete.

**Quantify value** — Time saved. Revenue gained. Cost reduced. Numbers beat vague claims.

**Speed up decisions** — When they see the ROI, objections fade. "Worth it" becomes obvious.

Elements

**Current cost** — Time, money, or both. What do they spend today? "10 hours per week on X." "$Y per month on Z."

**Your solution cost** — Your price. What they'll pay.

**Savings or revenue gain** — What they get. "Save 8 hours per week." "Increase revenue by $X."

**Payback period** — How long until they break even? "3 months." "6 months." Quick payback = easy yes.

Tools

**Spreadsheet** — Simple. Flexible. Share as Google Sheet. Good for MVP.

**Coda, Notion** — Interactive. Can embed. More polished.

**Calconic, Calculator.net** — Embeddable calculators. Customizable. For when you want it on your site.

Keep It Simple

**3–5 inputs** — Don't overwhelm. Key variables only. More inputs = more friction.

**Clear output** — One number. "Your annual savings: $X." Or: "Payback in 4 months." Obvious. Actionable.

Use in Sales

**Share before call** — "Here's a quick calculator. Plug in your numbers." They come to the call with context.

**Walk through on demo** — "Let's use your real numbers." Customize. Make it personal.

**Leave behind** — After the call. "Here's the ROI we discussed." Reinforces the value.

**Customize per prospect** — When possible. Their industry. Their size. Their numbers. More relevant = more persuasive.
