OVH (Overhead) Calculator
Use this tool to estimate your monthly overhead, overhead rate per productive hour, break-even price, and suggested bill rate.
Tip: Productive hours should only include revenue-generating hours, not total hours worked.
What Is an OVH Calculator?
An OVH calculator is a practical tool for estimating overhead (indirect) business costs and translating those costs into an hourly or per-job rate. OVH is short for overhead, and overhead includes all the necessary expenses that keep your operation running but are not directly tied to one specific sale or project.
Examples of overhead costs include rent, utilities, software subscriptions, business insurance, administrative support, accounting fees, and office operations. If you do not track overhead correctly, you may set prices too low and unknowingly lose money even when sales look healthy.
Why Overhead Matters for Pricing
Many owners price services using only direct labor and materials. The missing piece is overhead allocation. Without it, each job under-recovers true business costs.
- Freelancers: Need to recover software, marketing, taxes, and admin time.
- Agencies: Must allocate management salaries, tools, and non-billable team support.
- Contractors: Need to include transportation, equipment maintenance, and back-office operations.
- Manufacturers: Depend on overhead rates for accurate job costing and margin analysis.
Using an OVH calculator helps convert vague monthly expenses into concrete pricing decisions.
How This OVH Calculator Works
Step 1: Add monthly overhead costs
Enter fixed and semi-fixed indirect costs such as office rent, utilities, admin salaries, insurance, subscriptions, and other recurring overhead items.
Step 2: Enter productive hours
Productive hours are the hours that can be billed or tied directly to revenue. If your team works 160 hours per month but only 110 are billable, use 110.
Step 3: Enter direct labor cost and margin target
Direct labor cost is what it costs you per hour before overhead and profit. Margin target helps estimate a recommended bill rate rather than just break-even pricing.
Step 4: Review your results
The calculator returns:
- Total monthly overhead
- Annualized overhead
- Overhead per productive hour
- Fully loaded cost per hour (labor + overhead)
- Suggested bill rate for your target margin
Core Formula Reference
If you want to verify calculations manually, these are the key formulas:
- Total Overhead = sum of all monthly overhead inputs
- Overhead Rate per Hour = Total Overhead / Productive Hours
- Fully Loaded Cost per Hour = Direct Labor Cost + Overhead Rate per Hour
- Suggested Bill Rate = Fully Loaded Cost per Hour / (1 - Profit Margin)
Example: If fully loaded cost is $60/hour and target margin is 20%, suggested bill rate = 60 / 0.80 = $75/hour.
Common Overhead Pricing Mistakes
- Using total hours instead of billable hours (this dilutes overhead rate unrealistically).
- Ignoring small recurring costs like tools, cloud apps, merchant fees, and support subscriptions.
- Not updating overhead monthly or quarterly as expenses change.
- Confusing margin and markup (they are not the same percentage).
- Failing to include owner compensation in labor assumptions.
How to Improve Your Overhead Position
1) Increase utilization
If more team time becomes billable, your overhead per productive hour drops naturally.
2) Audit recurring expenses
Cancel duplicate tools, renegotiate software tiers, and review insurance/telecom contracts annually.
3) Standardize processes
Automation and templates reduce admin load and protect margin without cutting quality.
4) Reprice deliberately
Use updated overhead numbers to set new pricing every quarter instead of reacting when cash flow is tight.
Who Should Use an OVH Calculator?
This approach is especially useful for consultants, agencies, legal and accounting firms, trades, studios, repair businesses, and small manufacturers. If your business has indirect costs and variable billable capacity, overhead pricing is essential.
Final Thoughts
An OVH calculator turns financial guesswork into measurable decisions. By pricing from fully loaded cost instead of direct cost alone, you can protect margin, stabilize cash flow, and scale with confidence. Revisit your numbers regularly, especially when hiring, changing tools, or expanding your service offerings.
