How the Money per Hour Calculator works
This tool answers a simple but easy-to-fudge question: what does your time actually pay? It starts with the basic definition — earnings divided by hours worked — then layers in the costs and unpaid time that a plain "earnings ÷ hours" figure leaves out, so you get a rate you can trust when comparing jobs, gigs, or projects against each other.
The formula
The gross rate is the simplest version:
Gross Rate = Earnings ÷ Hours Actively Worked
The net rate subtracts any out-of-pocket costs (supplies, mileage, software, fees) from earnings before dividing:
Net Rate = (Earnings − Expenses) ÷ Hours Actively Worked
The true effective rate goes one step further, adding unpaid time — commuting, setup, admin, waiting on approvals — to the hours in the denominator:
True Effective Rate = (Earnings − Expenses) ÷ (Hours Worked + Unpaid Time)
Finally, the calculator annualizes the true rate against 2,080 hours (40 hours a week × 52 weeks), the standard full-time work year used in salary conversions, so you can see what that rate would amount to over a full year.
Worked example
Take the calculator's defaults: $500 earned for 10 hours of active work, plus 2 hours of unpaid time and $50 of expenses. The gross rate is $500 ÷ 10 = $50.00/hr. Subtracting the $50 of expenses gives net earnings of $450, so the net rate is $450 ÷ 10 = $45.00/hr. Adding the 2 unpaid hours brings total time to 12 hours, so the true effective rate is $450 ÷ 12 = $37.50/hr — about 25% lower than the gross figure. Annualized at 2,080 hours, that true rate works out to roughly $78,000 per year.
What moves the rate most
- Unpaid time: commuting, prep, invoicing, and waiting on replies rarely make it onto a timesheet, but they still consume hours. The more unpaid time relative to worked time, the bigger the gap between gross and true rate.
- Expenses: materials, mileage, software subscriptions, and fees quietly reduce what you actually keep per hour, even when the headline earnings figure looks strong.
- Total earnings: raising the payment for the same hours lifts every version of the rate proportionally — it's the only lever that doesn't get diluted by time or cost adjustments.
Gross rate versus true hourly wage
Comparing job offers, gigs, or side projects by gross rate alone can be misleading: a job that pays more per booked hour but demands a long unpaid commute, or a gig with hidden material costs, may actually pay less per hour of your life than a lower headline rate with no unpaid overhead. Calculating a true effective rate — a concept long used in personal-finance writing to describe what a job "really" pays once every hour and dollar is accounted for — puts different opportunities on the same footing.
