Change the example inputs to match your business. Your entries stay in this browser; they are not sent to us.
Illustrative inputs are not industry benchmarks. These tools do not audit accounts, send messages or deploy services. Review every output before using it.
Build the budget from the job backwards
A campaign needs more than a daily spend setting. Start with the amount a new customer contributes after direct delivery costs, then work backwards through your sales process. How many qualified inquiries become customers? How many inquiries actually fit the service?
Enter your own observations where possible. If the business has never run ads, treat the inputs as assumptions to test. Do not borrow a click cost from an unrelated industry and call it a forecast.
Keep the stages separate
The calculator divides media spend by cost per click, then applies the visitor-to-inquiry rate, qualification rate and close rate. It includes management in total acquisition cost, but not in the number of clicks bought.
With the example inputs, $1,000 buys 200 clicks. A 5% inquiry rate produces 10 inquiries, 80% qualify and 25% of those buy: two customers. Their $1,000 total contribution does not cover $1,500 in media and management. That is useful to know before launch.
Change one assumption at a time
Try a stronger landing-page inquiry rate, a lower click cost or a different contribution per customer. Watch which assumption does the most work. If the model only works with an unusually high close rate, the campaign needs more thought.
Check capacity too. A promising campaign can disappoint if nobody answers inquiries or there are no appointments available. Advertising and operations share the result.
What this leaves out
The model does not include creative production, subscriptions, tax, repeat purchases or delayed sales unless you include those costs in your planning separately. A fractional customer is an expected scenario value, not a literal booking.
Use a test budget you can afford to learn from. Compare measured results with the assumptions, then decide whether to continue, change the offer or stop.
Common questions
Is this an ad-platform forecast?
No. It is a transparent planning model using your inputs. It does not query Google or Meta.
Why does a zero click cost fail?
A zero denominator cannot produce a meaningful paid-click estimate. Enter a positive assumed cost per click.
