Details
These notes make the assumptions explicit, especially where the same search query can mean slightly different things.
Base project delivery value before overhead, expenses, buffer, and discounts.
Keeps normal uncertainty visible instead of hiding it inside the hourly rate.
Useful for comparing a fixed-fee proposal against day-rate, retainer, or hourly alternatives.
Benchmarks
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.
Anchor the quote in real delivery effort before adding business costs.
Useful for normal uncertainty, but large buffers should trigger scope clarification.
Compare against the minimum rate needed for utilization, taxes, downtime, and margin.

FAQ
No. This calculator prices one fixed-scope consulting project. A freelance rate calculator works backward from income goals, billable days, expenses, and taxes.
That depends on the contract and client expectation. If expenses are pass-through costs, keep them explicit. If you manage procurement risk, use overhead or scope buffer deliberately.
Fixed project fees can look strong while hiding too many hours. The effective hourly rate helps compare the proposal against day-rate, retainer, and utilization targets.
No. Business tools are scenario planners. Contracts, taxes, payment timing, accounting treatment, refunds, and legal requirements can change decisions.
Save the assumptions, compare a conservative scenario, and review the result with actual books, contracts, or an advisor before making a high-stakes decision.
Different tools may use different rounding, assumptions, default rates, methods, formulas, or input timing. Compare the visible method and inputs before relying on the output.
