Calculator use

Best for

  • Use this client profitability calculator to see whether a client, account, or retainer is profitable after delivery time, support time, tools, and pass-through costs.
  • Checking client profitability formula with the formula and assumptions visible.
  • Comparing the result with the sample calculation and benchmark table before using it elsewhere.
  • Pricing, runway, cash flow, or work assumptions before an operating decision.

Before relying on it

Check first

  • Using the client profit without confirming that monthly revenue, delivery hours and admin hours describe the same real-world case.
  • Ignoring that include support and admin time so the result reflects the true cost of serving the client.
  • Relying on the number without checking whether the visible assumptions match the real-world task.
  • Mixing cash and accounting profit, or monthly recurring items and one-time items.

Benchmarks

How to read the result

The calculator is a decision aid, not a fixed rule. Use the output to compare scenarios and document your assumptions. Benchmark ranges are broad planning heuristics unless this page names a specific source for the range.

Low profit per hourReview scope

A broad heuristic that the account may be underpriced or over-serviced.

High revenue, low marginCost heavy

Large clients can still be weak if pass-through costs, support, or delivery time are high.

Healthy marginRepeatable

Profitable clients usually have clear scope, low rework, and controlled communication load.

FAQ

Common questions

What is client profitability?

Client profitability is the profit left from a client after labor, admin, tools, vendors, and pass-through costs.

Should admin and support time be included?

Yes. Client calls, reporting, project management, revisions, and support can materially change profitability.

What if pass-through costs are reimbursed?

If costs are fully reimbursed outside revenue, leave them out. If they are bundled into the fee, include them.

Can this replace accounting or legal advice?

No. Business calculators are scenario tools. Contracts, taxes, payment timing, accounting treatment, refunds, and legal requirements can change decisions.

What should I do after using a business calculator?

Save the assumptions, compare a conservative scenario, and review the result with actual books, contracts, or an advisor before making a high-stakes decision.

Why might another calculator show a different result?

Different calculators may use different rounding, assumptions, default rates, formulas, or input timing. Compare the visible formula and inputs before relying on the number.
