A scenario, not a universal ideal budget
The tool starts from a user-defined ceiling, then compares cautious revenue percentages and margin capacity. It never recommends borrowing or spending money the business marked as unavailable.
2. Split
Separate maintenance, experiments, production, and measurement.
3. Review
Increase only after a complete test produces useful commercial signals.
Three budget decisions
Maintain
Protect the channels and messages that already produce enquiries.
Test
Reserve a limited amount for one measurable experiment.
No ads
Use owned channels, local partnerships, reviews, and consistent follow-up.
Frequently asked questions
Is the tool really free and available without an account?
Yes. Calculation or generation is immediate, with no account and no email address.
Does AdSpark receive what I enter?
No. Values entered stay in your browser. AdSpark records only an anonymous usage event with the tool name and language, never your amounts or text.
What percentage of revenue should a small business spend on marketing?
There is no safe universal percentage. Stage, margin, capacity, seasonality, and cash position matter. This calculator shows transparent scenarios and always respects the spending ceiling you enter.
Does the tool publish automatically?
No. It prepares a structure for you to review, complete with verified facts, and publish yourself.
