ROI Calculator
Enter cost and revenue to get ROI.
$1,000 → $1,500 = 50% ROI.
Why teams use the ROI Calculator
The ROI Calculator answers a common founder or manager question about roi in seconds — no spreadsheet, no formula lookup. It's designed for quick decisions and back-of-the-envelope validation before you commit budget.
Inputs match the fields you'd see in a P&L, ad dashboard, or CRM export, so you can paste numbers straight in without conversion.
- Fast enough for meetings — recalculates as you type
- Clear metric labels (no jargon)
- Works across marketing, sales, and operations
- Pair it with the related calculators for a full model
How to use the result in a decision
A single roi number is rarely enough. Combine the ROI Calculator's output with a target (a goal margin, a break-even point, a return threshold) and treat the difference as your headroom.
If the headroom is small, add sensitivity: rerun the ROI Calculator with a lower price or higher cost and see how quickly the number flips. Robust decisions look good in both cases.
From back-of-the-envelope to a real model
The ROI Calculator is a starting point. When the decision is worth a full model, take the inputs into a spreadsheet, add scenarios, and share it with your team — the ROI Calculator then becomes the sanity check the team uses to confirm the model.
