Measure marketing return from revenue and spend: ROI as a percentage of profit and ROAS as revenue earned per dollar spent. Calculates in your browser.

Show the math

ROI measures profit against spend; ROAS measures revenue against spend:

ROI % = (revenue − spend) ÷ spend × 100

ROAS = revenue ÷ spend

ROAS counts gross revenue, so a campaign can be ROAS-positive but ROI-negative once costs are netted out. All math runs in your browser.

What this does

An ROI & ROAS calculator measures marketing return from revenue and spend — ROI as a percentage of profit and ROAS as revenue earned per dollar spent.

How to use it

  1. Enter the revenue.
  2. Enter the ad spend.
  3. Read the ROI percentage.
  4. Read the ROAS ratio.

How it works

A campaign can be ROAS-positive but ROI-negative once costs are counted. To cover the ad spend from gross profit alone, ROAS must be at least 1 ÷ your gross margin.

ROI = (revenue − spend) ÷ spend; ROAS = revenue ÷ spend

Understanding your result

ROAS is revenue earned per dollar of ad spend, while ROI counts the profit left after that spend. A campaign can look strong on ROAS yet lose money on ROI once costs are included, so judge both together. The ROAS you need depends on your margins: at a 25% gross margin, a 4× ROAS only just covers the ad spend.

Example

$4,000 revenue on $1,000 spend is a 4× ROAS and 300% ROI.

Frequently asked questions

What is the difference between ROI and ROAS?

ROAS compares revenue to spend; ROI compares profit (revenue minus spend) to spend. A campaign can be ROAS-positive but ROI-negative.

What is a good ROAS?

It depends on your margins. Break-even ROAS is 1 ÷ gross margin (4× at a 25% margin, 2× at 50%), and you need more than that to cover other costs and make a profit.
