How it works
How to calculate flat-rate gross pay
In a simple flat-rate setup, estimated gross for a period is flagged hours multiplied by your flat-rate hourly pay. Enter the hours you expect to be credited for the week or biweekly period, then your rate.
Flagged hours × flat-rate hourly pay = estimated gross
That figure is a planning estimate before taxes and deductions. Shops may also use guarantees, mixed hourly plans, or other rules this calculator does not model.
Flagged hours vs. clocked hours
Flagged hours come from completed jobs and labor guide time. Clocked hours are time at work. A tech can flag more or less than they clock, depending on the work, approvals, and delays. How flag hours work covers the terminology in more detail.
Efficiency percentage
When you enter clocked hours greater than zero, efficiency is flagged hours ÷ clocked hours × 100. Effective gross per clocked hour is estimated gross ÷ clocked hours. Leave clocked hours blank if you only want the gross estimate.
A realistic example
A technician flags 42.5 hours in a week at $30 per hour and clocks 40 hours:
- Estimated gross: 42.5 × $30 = $1,275.00
- Efficiency: 42.5 ÷ 40 × 100 = 106.3%
- Effective per clocked hour: $1,275.00 ÷ 40 = $31.88
- Annual projection at 52 weeks: $1,275.00 × 52 = $66,300 (estimate assuming consistent weekly earnings)
Limitations and assumptions
- Simple flat-rate math only—no overtime, guarantees, bonuses, or commissions.
- No taxes, deductions, or net-pay estimates.
- Annual figures assume the same period earnings hold across your working weeks.
- Biweekly annual projection uses period gross × working weeks ÷ 2.
- Your shop’s payroll rules may credit hours differently than your personal total.
FAQ
Common questions
Straight answers about what this calculator does—and what it doesn’t.
How do I calculate flat-rate pay?
Multiply the flagged hours credited for the pay period by your flat-rate hourly pay. That product is an estimated gross for the period, before taxes, deductions, guarantees, bonuses, or other shop-specific pay rules.
What is the difference between flagged hours and clocked hours?
Flagged hours are the labor hours credited from completed jobs. Clocked hours are the hours you are physically at work. They measure different things and do not have to match. How flag hours work explains the difference in more detail.
What does efficiency percentage mean?
Efficiency is flagged hours divided by clocked hours, shown as a percent. Above 100% means you flagged more labor time than you clocked; below 100% means the opposite. Shops and techs use the number differently, and it is only meaningful when you enter clocked hours.
What do Weekly and Biweekly mean for the hours I enter?
All flagged hours, clocked hours, and estimated gross apply to the pay period you select. Weekly means the hours for one week; biweekly means the hours for that two-week period. Switching the selector does not double or halve your inputs—it only changes how the annual projection is calculated.
Why is the annual figure only an estimate?
The annual projection multiplies this period’s estimated gross across your working weeks (and halves that product for a biweekly period). Real years vary with vacation, shop volume, warranty adjustments, and unpaid work, so treat the annual number as a planning estimate—not a promise.
Does this calculator include overtime, taxes, or complex pay plans?
No. It only multiplies flagged hours by a flat-rate hourly pay, optionally compares that with clocked hours, and projects an annual estimate. It does not model overtime, guarantees, minimum wages, bonuses, commissions, deductions, or taxes.
Beyond the estimate
Estimates show the math. Records help you check payday.
This calculator estimates pay from the hours you enter. Flat Rate Tracker helps technicians record repair orders, track flagged hours over the pay period, and compare those records with payroll when something looks off.
