Project spend$2500Ad spend, tools, production or one-off project budget.Revenue generated$7800Revenue attributed to the project.Delivery cost$1800Cost to deliver the sales generated by the project.

How to use this calculator

Start with conservative inputs, copy the result, then test a best-case and worst-case version. For production decisions, compare the estimate against actual accounting, analytics and payment data.

Formula

ROI compares the net gain from a project with the amount spent to produce that gain. It is most useful when the revenue and delivery costs can be tied to a clear campaign, channel or experiment.

Formula

ROI = (revenue - delivery cost - project spend) / project spend.

Example

Campaign ROI estimate

A founder spends $2,500 on a campaign that produces $7,800 in revenue and costs $1,800 to deliver.

Project spend: $2,500
Revenue generated: $7,800
Delivery cost: $1,800

The campaign has a $3,500 net gain and an estimated 140% ROI.

FAQ

Is ROI the same as profit margin?

No. ROI compares profit with the investment used to generate it. Profit margin compares profit with revenue.

What if project spend is zero?

ROI needs an investment amount to be meaningful. If there is no project spend, compare net gain, margin or opportunity cost instead.

Can this calculator prove attribution?

No. Attribution is often noisy. Treat the output as a scenario model and compare it with analytics, CRM and payment data.

Important limits

Attribution can be noisy. Treat one-channel ROI as directional, not absolute.
