Almost every contracting business asks the same question when it decides to take marketing seriously: how much do I put in. Too little and the investment dilutes without moving the needle; too much and you tie up cash without knowing if you will get it back. The answer is not a magic number, it is a percentage of your revenue tuned to your goal.
This calculator puts numbers behind that decision. Enter your annual revenue, choose whether you want to maintain position, grow, or grow aggressively, and fine-tune the exact percentage. You will see the recommended monthly and annual budget right away, and how to split it across channels.
How much to spend: the 5 to 10 percent range
The most repeated guidance, backed by both the U.S. Small Business Administration and the annual marketing spend surveys, puts the investment between 5 and 10 percent of revenue. It is not a law of physics, it is a starting point calibrated by thousands of businesses.
- 5% — Maintain position. You have a brand, reviews, and word of mouth. Marketing keeps the engine that already turns.
- 8% — Grow. You want more jobs than walk in on their own. You invest to take share.
- 12% — Aggressive growth. New firm or in full expansion: you build demand from zero and need presence fast.
The calculator uses these three points as a starting position, but the slider rules: move it to set the exact percentage that fits your margin and your cash flow.
How to split the budget
Having the total number is half the job. The other half is splitting it well. The split the tool suggests is built for the home-services buying cycle:
- Local visibility and GBP/SEO (35%). Most home-services demand starts with a local search. Your Google Business Profile and local SEO are what get you found when someone searches your service in your area. It is the foundation.
- Paid ads (30%). Google Ads and similar capture immediate demand: the person with an emergency searching right now. It pays to be on top while SEO has not ranked you yet.
- Website and content (20%). Drawing visits is useless if the page does not convert. This is the website that turns a visit into a quote request.
- Reviews and retention (15%). Asking for reviews systematically and reactivating past customers is the best-spent money in the trade: it amplifies everything above.
This split is a sensible starting point, not a dogma. If your site already converts well but nobody finds you, load more toward visibility. If you have traffic but few reviews, raise the last line.
Why newer firms spend more
An established firm benefits from an invisible asset: accumulated reputation, repeat customers, and ranking that took years to build. That engine generates demand almost by itself, and 5% is enough to keep it greased.
A new firm has none of that. Every customer costs more to win because it starts from zero on visibility and trust. That is why it makes sense to lean toward the high end of the range during the growth phase: you are buying the recognition and reviews that will later work for free.
What to do with the number
The budget is the start, not the end. The next step is making sure every dollar works. Start with visibility, where home-services demand is born, and check that your conversion system does not let what marketing brings slip away. If your bottleneck is how you run the work once it is booked, the operations page covers that part.
To measure whether the budget pays off, lean on the marketing KPIs and metrics for contractors guide and, if you will put part toward paid ads, on the Google Ads for home services guide.
