FAQ
How does the audience value calculator work?
Revenue per follower per year is the single number that compares a 5,000-person email list to a 500,000-follower TikTok. Owned channels usually win by an order of magnitude. The underlying maths is: RPF = Annual revenue from a channel ÷ Audience size on that channel.
What do I need to enter?
6 values: social followers, monthly revenue from social, email subscribers, monthly revenue from email, paying members / customers, and monthly revenue from members. Each field starts with a sensible default, so you can change one number at a time and watch the result move.
What does the total annual revenue 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.
