Can you afford NOT to increase your fees?
Most practices lose far fewer clients than they fear. Enter your numbers and see the actual figure — both the extra revenue, and how much room you have before a rise costs you anything.
How many clients pay you a recurring fee.
Roughly what an average client pays you each month.
The rise you're considering, across the board.
What if this many clients left because of the rise?
Add each client's own fee and their own increase. Churn below still applies as one rate across the list.
| Client | Fee (£/mo) | Increase % | Remove |
|---|---|---|---|
| Total (annual) | — | — |

Same client count and fee, three different increases.
This shows the change in recurring revenue only. It does not account for your cost base, capacity, or corporation tax, so treat it as a revenue estimate, not a profit forecast.
Client loss is an assumption you set, not a prediction. Real churn depends on how the increase is communicated and to whom, and the clients who leave are often the most price-sensitive ones rather than a random slice of your book, so the real picture is usually kinder than a flat percentage suggests.
It assumes fee increases apply from the start of the year shown and does not model phasing an increase in over several months.

A fee increase changes the maths on losing a client.
The size of the rise decides how many clients you could lose before it costs you money — the average fee itself doesn't change that number.
Your fee level doesn't change how many clients you can lose — only the size of the rise does.
Nobody knows the real number in advance. Test a few and see which ones still work for you.
This is what you'd bill, not what you'd keep. Costs and tax still come off it.
How you tell clients moves the churn number more than the size of the rise itself.
Fee increases, and what they actually do.
How much extra revenue does a fee increase actually bring in?
It depends on your number of clients, average fee, and how many clients leave. A 7 per cent increase across 150 clients paying £180 a month is roughly £22,700 a year before any client loss, and still comfortably positive after allowing for a few clients leaving.
How many clients can I afford to lose after a fee increase?
The break-even client count only depends on your number of clients and the size of the increase, not the fee itself. As a rule of thumb, a 7 per cent increase across 150 clients lets you lose around 9 clients and still collect the same revenue as before the rise.
Is client churn after a fee increase predictable?
No. Churn depends on the client relationship, the size of the rise, and how it is communicated, not just the percentage. This tool treats churn as a scenario to test, not a forecast, which is why it shows several assumptions side by side rather than one predicted figure.
Does this calculator account for tax or costs?
No. It shows the change in recurring revenue only, not profit. It does not account for your cost base, capacity, or corporation tax, so treat the output as a revenue estimate rather than a bottom-line one.
Does this calculator store or send my figures anywhere?
No. Everything you type stays in your browser. Nothing is saved, submitted or sent to us.
