ROI Calculator – Calculate Your Marketing ROI
What is marketing ROI?
Return on Investment (ROI) shows how much return a marketing investment generated relative to its cost. Unlike ROAS, ROI factors costs directly into the calculation and shows actual profit, not just revenue generated.

Example calculation
Marketing costs of $5,000 resulting in a return of $15,000 give an ROI of 200 percent. Every dollar spent tripled — $1 in cost plus $2 in profit.
Why the simple formula reaches its limits in marketing
The classic ROI formula assumes the return can be clearly attributed to a single channel or campaign. In practice, several channels usually contribute jointly to a purchase, and one channel can drive purchases in another without this showing up in an isolated view. Marketing also rarely works instantly — part of the return arrives with a delay, which distorts a pure snapshot.
Anyone who wants to correctly attribute ROI across multiple channels, account for time lags, and include cross-channel interactions needs a model that accounts for these factors together.

How to increase marketing ROI
- Sharpen audience targeting to reduce wasted spend
- Shift budget to channels with higher return per dollar
- Account for delayed purchase impact within the measurement window
- Use cross-channel interactions instead of single-channel views
ROI vs. ROAS vs. break-even
| Metric | Question it answers | Formula |
|---|---|---|
| ROI | How much profit per dollar spent? | (Return − Cost) / Cost × 100 |
| ROAS | How much revenue per dollar spent? | Revenue / Cost |
| Break-even | When are costs covered? | Fixed costs / (Price − variable costs) |
Frequently asked questions about marketing ROI
What counts as a good marketing ROI?
This depends heavily on industry, margin and channel. An ROI of 400 to 500 percent is often cited as solid, but comparing against your own past periods and channels is more meaningful than any general benchmark.
What is the difference between ROI and ROAS?
ROAS compares revenue generated to cost, without subtracting costs. ROI subtracts costs from the return and shows the actual profit relative to the amount spent.
Why does calculated ROI often differ from actual impact?
Because a single channel is rarely solely responsible for a purchase. Without correct attribution across multiple touchpoints, a channel's ROI is often over- or underestimated.
Should ROI be calculated on revenue or on profit?
For budget decisions, the profit-based calculation is more meaningful since it accounts for variable costs. The revenue-based version is simpler but overstates actual profitability.
How long should the measurement window be for an ROI calculation?
That depends on the sales cycle. Short purchase decisions need only a few weeks, while longer B2B cycles require a window wide enough to capture delayed purchases.
