Overhead Recovery Calculator
Reviewed by Gerald G., founder & reviewing editor of CalcAuthority. Formula-based tool: every result is computed from the stated formula and your inputs — no hidden adjustments.
Overhead is the cost of existing: rent, insurance, trucks, software, the phone plan, the bookkeeper, your salary for running things. No customer ever gets a bill for it — which is exactly the problem, because every customer has to pay a slice of it or the business slowly starves while looking busy. This calculator converts your annual overhead into the two forms operators can actually use: overhead per billable hour (to build into rates) and overhead as a percentage of revenue (to build into job pricing). Companion reading: Overhead: the invisible line item.
How It Works
Add up a full year of costs that are not chargeable to any specific job or sale — everything that would still bill you if you took a month off. Then choose your recovery base. Per billable hour fits businesses that sell time (trades, consultants, agencies): dividing overhead by the hours you can actually bill — not hours worked; estimating, driving, and admin do not count — gives the dollars each billable hour must carry before wages and profit. Percent of revenue fits job- and product-pricing: it is the share of every sales dollar spoken for before direct costs and profit divide the rest.
Both forms plug directly into the pricing tools: the hourly figure adds to your burdened labor rate (see the Labor Burden Calculator), the percentage feeds the Break-Even Job Price and Break-Even Revenue calculators. Use one or the other in a given price — using both double-charges the customer and loses you bids.
Worked Examples
Example 1 — small contracting company. Annual overhead $96,000 (office, two trucks, insurance, owner's management salary, advertising). Crew bills 3,200 hours/year. Overhead per billable hour = $96,000 ÷ 3,200 = $30/hour. On $480,000 revenue, overhead % = 20%. A crew hour whose burdened wage cost is $40 truly costs the company $70 before profit — quote $65/hour and the busier you get, the more you lose.
Example 2 — solo operator. Overhead $54,000 (vehicle, insurance, tools, phone, software, modest shop). Realistic billable hours: 1,500 (not 2,080 — estimating, supply runs, and admin are unbillable). Overhead per billable hour = $36/hour. This is why solo rates that look "high" are often just honest: $36 of every billed hour is spoken for before the operator earns a wage.
What This Result Means
The per-hour figure is the toll every billable hour pays for the business to exist — collect it in your rate or pay it out of your profit; there is no third option. The percentage form says what fraction of every sales dollar is pre-committed. If the numbers shock you, look at both directions before cutting: the denominator matters as much as the numerator — more billable hours spread the same overhead thinner, which is why utilization is a profit lever equal to any expense cut.
Reading the Result
- Overhead under 10% of revenue: very lean — verify nothing is hiding (unpaid owner management time is overhead someone is donating).
- 10–20% of revenue: the common range for small service businesses.
- 20–30%: not automatically wrong, but every bid must now consciously carry it; thin-margin work becomes unaffordable at this level.
- Above 30%: the business exists mostly to feed its own structure — either revenue must grow into the overhead or the overhead must come down.
Bands are editorial heuristics for small service businesses, derived from how the arithmetic squeezes margins at each level — not from a published industry survey. Capital-heavy trades legitimately run higher; keep the trend of your own number as the real benchmark.
When to Use This Calculator
Use this calculator:
- Annually, from your books — and again whenever a big fixed cost changes (new truck, new office, new hire in admin).
- Before setting hourly rates — rate = burdened labor + overhead per hour + profit; this supplies the middle term.
- Before bidding with a percentage — supply the overhead % to the Break-Even Job Price Calculator.
- When growth is on the table — adding capacity adds overhead first and revenue later; re-run with projected numbers to see the new recovery requirement.
Limitations
- The billable-hours denominator is the most commonly flattered input — count last year's actual billed hours, not this year's hopes.
- Treats overhead as one pool; multi-crew or multi-line businesses may need overhead allocated by division.
- A trailing snapshot: growing businesses should also run projected numbers.
- Owner compensation split matters — management time is overhead, tool-belt time is direct labor; splitting it wrong distorts both this number and your labor burden.
Frequently Asked Questions
What exactly counts as overhead?
Anything you cannot honestly charge to a specific job or sale: rent and utilities, insurance policies, vehicles used across jobs, office staff and bookkeeping, software, marketing, licenses, interest on business debt, and the management portion of owner pay. The test: if you paused all jobs for a month, what bills still arrive? Materials and job-site labor are not overhead — they belong in direct costs.
Should I use hours or percentage for recovery?
Pick the one that matches how you price. Time-sellers (hourly trades, consultants) fold the per-hour figure into their rate. Job- and project-pricers use the percentage in their bid formula. The only mistake is mixing them in one price — overhead in the labor rate and again as a bid percentage — which quietly inflates quotes and costs you work without you knowing why.
My overhead percentage looks high. Cut costs or raise revenue?
Do the arithmetic both ways before deciding. Cutting $10,000 of overhead helps immediately but has a floor — some structure is what lets you deliver at all. Raising billable utilization or prices shrinks the percentage without cutting capability: the same $96,000 overhead is 20% of $480,000 revenue but 16% of $600,000.
