← Subscription price impact calculator
A price increase does not have to cause zero churn to be worth doing — it only has to cause less churn than the break-even rate. Raising price without knowing that number means guessing whether the customers you'll lose are a rounding error or the whole gain, wiped out.

Break-even churn, not zero churn. The revenue break-even point is the subscriber count where current price × current subscribers equals proposed price × subscribers left. A 25% increase can lose a fifth of subscribers and still bill the same as before the change.
Fixed costs do not move with churn. Contribution (revenue minus your fixed monthly costs) reacts to the same churn scenarios differently than revenue alone, because the fixed-cost line stays constant while revenue shifts under it.
Five scenarios, not one guess. The calculator prices 0%, 5%, 10%, 15%, and 20% churn side by side, so you can see exactly where contribution stops improving and starts falling.
100 subscribers pay $20 a month ($2,000 current revenue) against $500 in monthly fixed costs. Raising the price to $25 puts revenue break-even at 80 subscribers — a maximum churn rate of 20% before revenue falls below $2,000. At exactly 20% churn, 80 subscribers remain, revenue is $2,000, and contribution is $1,500 — unchanged from before the increase because fixed costs stayed at $500. At a more likely 10% churn, 90 subscribers remain, revenue rises to $2,250, and contribution rises to $1,750 — $250 better than before the price ever moved.
The break-even churn rate is 1 minus the ratio of your old price to your new price. Raising price from $20 to $25 is a 25% increase, and the ratio 20/25 = 0.8 means recurring revenue stays at or above today's level up to 20% subscriber churn. Above that, even though each remaining subscriber pays more, revenue falls below where it started.
At exactly the break-even churn rate, revenue lands back where it started — 100 subscribers at $20 and 80 subscribers at $25 both bill $2,000 a month. Contribution (revenue minus fixed costs) also lands unchanged, because fixed costs do not move with subscriber count. Any churn below that rate leaves both revenue and contribution higher than before the increase.
Yes. The calculator subtracts your entered monthly fixed costs from projected revenue at each of five churn scenarios — 0%, 5%, 10%, 15%, and 20% — so you can see contribution, not just top-line revenue, at each churn level before deciding.
