How it works
Methodology & formulas
This calculator is transparent by design. Review the steps and formulas so you can trust the estimate and adjust assumptions when your dashboard differs.
Calculation steps
- 1Calculate paid subscribers from list size and free-to-paid conversion.
- 2Calculate recurring newsletter and product revenue.
- 3Reduce gross revenue by refunds, then apply Kit commerce and processor costs.
- 4Subtract Kit account cost, payout, software and content, marketing, and overhead.
- 5Calculate pre-tax profit, margin, reserve, after-reserve profit, hourly profit, and paid-subscriber break-even.
- 6Keep all uncertain Kit terms editable and visible.
Formulas
- Paid subscribers = list size x free-to-paid conversion
- Recurring revenue = paid subscribers x newsletter price
- Product revenue = product sales x average product price
- Collected revenue = gross revenue x (1 - refund rate)
- Pre-tax profit = collected revenue - Kit fee - processing - Kit cost - payout - software and content - marketing - overhead
- After-reserve profit = pre-tax profit - max(0, pre-tax profit) x reserve rate
- Break-even paid subscribers = ceiling(max(0, fixed costs - product contribution) / paid subscriber contribution)
Important assumptions
- Paid subscribers are list size multiplied by free-to-paid conversion. This is a planning count, not a conversion forecast or churn model.
- ConvertKit is now Kit. Monthly account cost and commerce percentage are user-entered because current terms vary. No official current values are claimed.
- Refunds reduce collected revenue before Kit and processor percentage fees. Processor fixed fees apply to paid newsletter charges plus product sales.
- Software and content, marketing, other overhead, payout cost, and Kit account cost are separate monthly costs and should each be entered once.
- Break-even paid subscribers uses pre-tax contribution and holds product sales, prices, costs, and Kit terms constant. Tax reserve is cash planning only.
