FAQ
How does the email list revenue calculator work?
Revenue per subscriber per month is the number that tells you what a new signup is actually worth — and therefore how much you can pay to acquire one. The underlying maths is: Revenue = List × Open rate × Click rate × Conversion rate × Order value.
What do I need to enter?
6 values: subscribers, open rate, click rate (of opens), click to purchase rate, average order value, and campaigns per month. Each field starts with a sensible default, so you can change one number at a time and watch the result move.
What does the revenue per campaign result mean?
It is returned as a money amount in US dollars and updates live as you edit the inputs, so you can compare two or three versions of a scenario in a few seconds.
Is this calculator free, and do I need an account?
Yes, it's free, and no account is required. Nothing you type is stored on our servers — the maths runs entirely in your browser.
How accurate is the result?
It applies the standard formula exactly, so the arithmetic is precise. Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
Who is this tool for?
It's built for anyone comparing money scenarios before committing — budgeting a payment, sanity-checking a quote, or seeing what a change in rate or term actually costs.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
