Interpretation

How to read the result without fooling yourself

The calculator gives you a quick viability read. If ROI is positive, the numbers you entered mean the campaign covers ad cost. If it is negative, you have not reached break-even yet and need to improve conversion, average order value, or acquisition efficiency.

The final number is not the only useful signal. The gap between your current conversion and the conversion needed for break-even matters too. A small gap may need a tactical fix. A large gap usually points to issues beyond ads — offer, landing page, or sales process.

FAQ

Frequently asked questions

What data do I need to use the calculator?

Use monthly ad spend, monthly clicks, conversion rate, and average order value. With those four inputs, the estimate can already project revenue and profitability in a useful way.

What does break-even mean in this calculator?

Break-even is the revenue or conversion level needed to recover your monthly ad spend. Beyond that point, the campaign starts generating positive return.

Does the result equal actual business profit?

No. It is a quick estimate for more informed decisions. Real ROI also depends on margin, recurrence, sales quality, returns, and attribution.
