Overhead is the cost of staying open: rent, tools, software, insurance, bookkeeping, marketing, utilities, licenses, admin time, and fixed vehicle or equipment costs. These costs do not disappear just because a single job, order, or appointment looks profitable on direct costs.
If overhead is not included in pricing, profit usually gets overstated. A quote can cover materials and labor and still fail to pay for the business systems needed to deliver the work.
Overhead Per Order Formula
The simplest method is: overhead per order = monthly fixed overhead / expected monthly orders. Add that amount to the job or product cost before payment fees and target profit.
| Overhead category | Examples | Pricing note |
|---|---|---|
| Workspace and operations | Rent, utilities, storage, phone, internet, scheduling software | Use the monthly amount even if one job does not use the whole resource |
| Risk and compliance | Insurance, licenses, permits, professional fees | These often support every job, not one specific customer |
| Tools and systems | Equipment, maintenance, subscriptions, bookkeeping, invoicing tools | Include recurring costs and a realistic replacement allowance |
| Admin and selling time | Quotes, follow-up, email, ordering supplies, marketing, bookkeeping time | Owner admin time should still be covered by prices |
Example
If monthly overhead is $2,000 and you expect 50 orders, each order should carry about $40 of overhead before profit. If volume drops to 25 orders, overhead per order becomes $80. The same direct-cost job now needs a higher price or a lower fixed-cost base.
This is why the expected volume input matters in the calculator. A business with strong demand can spread fixed costs across more orders. A business with slower volume needs each order to carry more of the monthly cost.
When volume drops, overhead per order rises. Revisit your pricing assumptions whenever order volume, route capacity, appointment count, or monthly fixed costs change.
Quick FAQ
Should overhead be added before or after profit?
Add overhead before calculating target profit. Otherwise the quote may hit a margin on direct costs while still failing to pay for fixed business costs.
What if I do not know my exact overhead?
Use a conservative monthly estimate and improve it as bookkeeping gets cleaner. A rough overhead estimate is better than pretending fixed costs are zero.
Should seasonal businesses use annual overhead?
Often yes. If revenue comes in during a season but costs continue all year, divide annual fixed costs across the realistic number of paid seasonal jobs or orders.
