Do the sums yourself. We will show every assumption.

You price work for a living, so you will spot a made-up number faster than anyone. Every input below is yours, every assumption is on screen and editable, and the workings are set out like a schedule. If the arithmetic does not hold up, do not buy it.

The assumptions
Ours, not hidden. Change them.

These two are the only things we are asserting. Everything else above is your own data.

The only number that matters first
4.6
new clients a year to cover the spend entirely
Roughly one every couple of months. At €2,400 a year and 55% margin, each new client contributes €1,320 against an annual spend of €6,000.
If the assumption holds
New clients a year16.8
Extra fee income, year one€40,320
Contribution after cost of delivery€22,176
Less the annual spend−€6,000
Net, year one€16,176
Over the life of those clients
€125,232
Contribution from one year of new clients, held for 7 years, less the spend over the first 5. It assumes you never win another client after year one, which is not how any of this works.

Every line, in order, so you can pull it apart

No hidden multipliers and no compounding we have not shown you.

Year one only. Nothing here assumes those clients stay, refer anyone, or take on additional services — all three of which is where the real money usually is.

Now assume we are wrong

The number that should decide it is the bottom one

Same inputs, our assumption cut back. If the pessimistic case still works, the decision is easy.

A quarter as effective
−€456
1 extra enquiry a month — behind, worth knowing now
Half as effective
€5,088
2 extra enquiries a month — still ahead
As assumed
€16,176
4 extra enquiries a month — still ahead

It works at half the assumption, not at a quarter.

At half effectiveness you net €5,088; at a quarter you are €456 down in year one. Given clients stay 7 years, that first year is recoverable — but go in knowing where the floor is.

Notes to the schedule

Six things the arithmetic above does not capture

Each one is tied to the line it affects, and to whether it flatters the answer or hurts it. Three of the six work against us.

NoteWhat is not in the modelEffect on the answer
1Nothing happens in month oneThe map moves in roughly ninety days. Multiplying by twelve assumes an even year, which overstates the first quarter and understates the fourth. The annual figure is about right; the shape of it is not.Applies to line 2Flatters year one
2Your town has a ceilingOnly so many people search for an accountant near you each month. In a town of 8,000 the enquiry slider has a hard upper limit no amount of work moves, whatever anyone tells you. The audit gives you the actual search volume.Caps line 1Flatters the assumption
3Capacity is a costSeventeen new clients may mean a hire, and a hire changes the margin you entered at the top. If you would need to take someone on, drop the margin slider and run it again before believing the net.Pressures line 5Flatters the margin
4Enquiries are not clientsWe can put the phone call in front of you. Whether it converts depends on who answers and how fast — which is exactly why response time is a line in your monthly report rather than something we quietly leave out.Sits inside line 3Depends on you, not us
5It ignores the upside entirelyNo referral effect from new clients, no additional services sold to them, no price increase from being the firm people want. All three are real and all three are excluded, because guessing at them is what makes calculators dishonest.Omitted from line 4Understates the answer
6It is a model, not a forecastYou would not sign off a client projection built on two assumptions, and neither would we. This exists to tell you whether the conversation is worth an hour, not to tell you what next year looks like.Applies throughoutUse it as indicative
