Rounding: Rates round to 2 decimal places.
An independent engineer wants $90,000 net take-home pay working 48 weeks/year at 40 hrs/week with 65% billable utilization.
Independent consultants spend roughly 30%–35% of their week on lead generation, proposals, invoicing, bookkeeping, and continuing education that cannot be billed directly to a client.
Reverse-engineer your required hourly, daily, and weekly consulting rate from your target net pay, overhead, taxes, and realistic billable utilization.
The defaults are illustrative. Replace them with values for your case and keep the units shown beside each field.
With the default values shown, Recommended Billable Hourly Rate is USD 109.78/hr. The calculation follows Billable Utilization & Tax-Grossed Freelance Pricing Equation; the formula and variable definitions above show how the inputs combine.
One-input check: With the other defaults held constant, changing Target Annual Net Take-Home Pay from 90,000 USD / yr to 99,000 USD / yr changes Recommended Billable Hourly Rate from USD 109.78/hr to USD 119.79/hr. This is a comparison inside the calculator's stated model, not a prediction.
Scope: Global Check the assumptions and limitations against your situation before relying on the estimate.
