The 5% Rule Was Never Written For You.
Run the percentage-of-revenue rule and the actual cost of your growth target against the same revenue number. When they disagree — and they usually disagree badly — this tells you which one is lying.
Your Numbers
Last twelve months, not your best year.
How much you want revenue to grow over the next twelve months. This is what the bottom-up budget has to fund.
The top-down rule of thumb you have been told to use. For scale: specialty trade contractors filing Schedule C actually deducted 0.60% of receipts on advertising (IRS SOI, TY2023).
The share of new revenue you expect from existing customers and word of mouth. Marketing does not have to buy this part.
Starts at $41.26, the Home & Home Improvement median across 726 US Meta lead campaigns (WordStream/LocaliQ). Paid search runs $90.92.
Your blended rate from the CRM, not your best salesperson's.

The work behind it
Your two budgets disagree by $40,617
The percentage rule funds $75,000, but your growth target only costs $34,383 to buy. Either the target is unambitious relative to what you can afford, or you are about to spend the difference on media your schedule cannot absorb. Check the capacity side before you spend to the percentage.
What contractors actually deduct — IRS Statistics of Income, tax year 2023
| Filer group (Schedule C) | Advertising as % of receipts | Per return |
|---|---|---|
| Specialty trade contractors | 0.596% | $609 |
| Construction, all subsectors | 0.512% | $582 |
| Construction of buildings | 0.341% | $488 |
| Heavy & civil engineering construction | 0.323% | $670 |
| All nonfarm industries | 1.178% | $781 |
Computed from IRS Statistics of Income, Nonfarm Sole Proprietorship Income Statements, Table 2, tax year 2023 — advertising deductions divided by total business receipts. Covers Schedule C filers only, so it excludes S-corporations and C-corporations, where most contractors above roughly $1M in revenue file. It also counts only what landed on the advertising line: agency retainers frequently sit under legal and professional services or other business expenses instead, and the owner's own selling time is never in there at all. Read it as a floor on what the self-employed half of the trade spends, not as a target.

What percentage of revenue should a contractor spend on marketing?
No percentage survives contact with your close rate, which is why this planner refuses to give you one. Work out what the growth target costs in leads, price those leads, then check the result against revenue. Between 3% and 8% is ordinary. At 15% the problem is the funnel, not the budget — and no percentage rule will ever tell you that, because it never looked at your funnel.
What do contractors actually spend on advertising?
Far less than the advice implies. In tax year 2023, 2,521,516 specialty trade contractors filing Schedule C deducted advertising equal to 0.596% of business receipts — about $609 per return — against 1.178% across all nonfarm industries. That is IRS data on real filings, not a survey. It does not tell you what to spend, but it does tell you that the businesses the 5-10% rule describes are not the ones filing these returns.
Why do the two budget methods disagree?
Because one of them is derived from your business and the other is borrowed from an average. The bottom-up figure moves with your close rate, your ticket and your cost per lead; the percentage moves with nothing. When bottom-up runs far above the percentage, raising the budget is the most expensive of your three options — improving the close rate cuts the required spend proportionally and costs nothing in media.

Budget Questions.
What percentage of revenue should a contractor spend on marketing?
There is no percentage that survives contact with your close rate. The honest answer is to calculate what your growth target costs in leads, then check that figure against revenue — if it lands between 3% and 8% you are in ordinary territory, and if it lands at 15% your close rate or your cost per lead is the problem, not your budget.
Why does this tool argue against the 5-10% rule?
Because the rule is borrowed from cross-industry marketing surveys of large firms and was never calibrated to trades. IRS Statistics of Income data for tax year 2023 shows 2,521,516 specialty trade contractors filing Schedule C deducted advertising equal to 0.596% of business receipts. The rule and the reality are an order of magnitude apart.
Does 0.6% mean I should only spend 0.6% of revenue?
No, and reading it that way inverts the point. It is a description of what the self-employed half of the trade does, not a recommendation — and most of those filers are one-truck operators running on word of mouth. Use it to understand that the 5-10% advice describes almost nobody in your industry, then size your own budget from your own funnel.
Why is the IRS figure so much lower than every marketing article?
Three reasons, and all of them matter. It covers Schedule C sole proprietors only, so the larger S-corporation contractors who spend most heavily are absent. It counts only what landed on the advertising line, while agency retainers often sit under legal and professional services. And it cannot see the owner's own selling time, which is the largest marketing cost in a small contracting business.
Which number should I actually budget to — top-down or bottom-up?
Bottom-up, every time, with top-down as the sanity check. The bottom-up figure is derived from your close rate, your ticket and a real cost per lead, so it describes your business. The percentage describes an average of businesses that are not yours, and its only genuine use is telling you when the bottom-up answer has gone somewhere strange.
What if the two budgets disagree by a lot?
That gap is the finding, not an error. When bottom-up runs far above top-down, your growth target is priced beyond what your funnel can convert — and raising the budget is the most expensive of the three available fixes. Improving the close rate reduces the required spend proportionally and costs nothing in media.
Should the marketing budget be a percentage of revenue or of gross profit?
Gross profit is the more honest denominator, because that is the pot the spend actually comes out of. A 45%-margin service business and a 22%-margin installation business with identical revenue can afford very different budgets, and a revenue percentage hides that completely. This tool shows gross profit on the new work for exactly that reason.
Why does the planner subtract repeat and referral revenue?
Because marketing does not have to buy revenue that arrives on its own. If a quarter of your growth comes from existing customers and word of mouth, budgeting to fund all of it means overpaying for leads you were going to get anyway — one of the most common ways contractor budgets get inflated without anyone noticing.
What cost per lead should I put in?
Your own, if you have thirty days of data. The default is $41.26, the Home & Home Improvement median across 726 US Meta lead campaigns (WordStream/LocaliQ). Paid search runs far higher at $90.92 per lead across 13,474 campaigns, so run the planner once per channel rather than blending them.
Does the return-per-dollar figure include overhead?
No, and that is deliberate. It shows gross profit on the new work divided by media spend, so anything under 1.0x is losing money before overhead is even considered. A healthy contractor wants that figure well above 3x, because overhead, management fees and the jobs that fall through all come out of the same gap.
How does this differ from the Ad Budget Forecaster?
The forecaster starts from a budget you pick and projects it forward over three to twenty-four months. This starts from a revenue goal and works out what that goal costs, then checks it against a percentage rule. Use this one to set the number and the forecaster to model what it compounds into.
How does this differ from the Lead Capacity Planner?
The capacity planner works up from what your crew can physically complete and returns a ceiling. This works down from what you want revenue to do and returns a requirement. Where the requirement exceeds the ceiling, the capacity planner wins the argument — you cannot buy growth your schedule cannot deliver.
Should a new contractor spend more than an established one?
Almost always, because a new business has no repeat base and no referral flow to subtract. Set the repeat and referral share near zero and the required budget rises sharply — that is not a flaw in the model, it is the actual cost of not yet having customers.
Does the budget include agency management fees?
Not by default. The bottom-up figure is media spend only, so add management fees on top before comparing it against a percentage of revenue — otherwise you are comparing a media number with a total-marketing number and the gap will look smaller than it is.
Are any of these numbers Elev8 Operations data?
None of them. The advertising table is computed from IRS Statistics of Income tax-year-2023 filings, the cost-per-lead defaults are from WordStream/LocaliQ's published benchmarks, and the ticket sanity check is from SearchLight's LSA dataset. Every input describing your business comes from you, because no dataset knows your close rate.
