WRAP Rate Calculator
This calculator works in the piecework sense of WRAP rate: enter total hours worked, total earnings and total pieces produced, and it returns the earnings per piece and the earnings per hour for that run of work. It is the production-floor version of the rate, used in manufacturing, packing, garment work and fulfilment to price a job, check a piece rate, or see what a shift actually paid per unit. One naming note: in government contracting, “wrap rate” means a fully burdened labor multiplier, which is a different calculation and is not what this tool does.
Both rates come from the same three figures, so keep the period consistent: one shift, one week or one production run, with hours, earnings and pieces all covering that same stretch.
Quick Answer
A packaging worker who produces 500 pieces in 8 hours and earns $200 has a WRAP rate of $0.40 per piece and an hourly rate of $25.00 per hour, at an output pace of 62.5 pieces per hour. The per-piece figure is what each unit cost in labor; the hourly figure is what the same work paid per hour. Enter your own hours, earnings and pieces above to get both rates for your shift, week or production run.
Key takeaways
- WRAP rate here is a piecework rate: total earnings divided by pieces produced. It answers “what did each unit cost in labor?”, not “what should we charge per hour of loaded labor?”.
- The hourly rate beside it, total earnings divided by hours worked, is the same division the U.S. overtime rules use to find a pieceworker’s regular rate for a workweek.
- Keep the three inputs on the same period. Mixing a week’s earnings with one shift’s pieces produces a rate that describes nothing.
- The tool adds no overtime premium and no material costs. If earnings include materials, the per-piece figure includes them too.

How to use the WRAP rate calculator
Enter one period of work, three numbers in total, and click Calculate. The results stay hidden until you calculate.
- Total hours worked: the hours behind this run of work. For a team, add everyone’s hours together, because the earnings and pieces figures will be team totals too.
- Total earnings: the pay or labor cost for that same period. Include production bonuses or waiting-time pay if you want them inside the rate; leave materials out for a pure labor rate.
- Total pieces produced: finished units in that period. Rejected or reworked units only count if they were eventually completed and paid for.
- Read both rates together: the WRAP rate per piece for pricing and unit labor cost, the hourly rate for pay comparisons and the minimum wage and overtime checks below. The badge under the results shows the output pace, pieces per hour, that connects the two.
If hours or pieces are zero, blank or missing, the tool stops with “Please enter valid positive values.” rather than dividing by zero. Earnings of $0 are accepted and return $0.00 rates, which is the honest answer for unpaid trial work; a negative earnings figure also passes through and produces a negative rate, a sign the inputs describe a loss, not a wage.
The two formulas behind the rate
Each output is a single division. There is no hidden weighting, no rounding before the final step, and both results are shown to two decimal places.
Hourly rate = Total earnings ÷ Total hours worked
The hourly division is not just a convenience figure. Under the federal overtime regulation for pieceworkers, 29 CFR 778.111, a pieceworker’s regular rate for a workweek is found by adding all earnings for the week and dividing by the hours worked in that week, which is exactly this tool’s second output when the inputs cover one workweek. That regular rate then drives the overtime premium described below. For a wider view of output per hour across a workforce, the labor productivity calculator works the production side of the same relationship, while this page prices it.
Worked example: a packing shift, checked four ways
The pre-filled example is a single packing shift: 500 pieces in 8 hours for $200 of earnings. The WRAP rate is $200 ÷ 500 = $0.40 per piece and the hourly rate is $200 ÷ 8 = $25.00 per hour.
The same arithmetic on three other real runs of this calculator:
| Run | Hours | Earnings | Pieces | Per piece | Per hour |
|---|---|---|---|---|---|
| Packing shift (worked example) | 8 | $200.00 | 500 | $0.40 | $25.00 |
| Team week, four packers combined | 40 | $1,200.00 | 2,400 | $0.50 | $30.00 |
| Short shift, fractional hours | 7.5 | $187.50 | 375 | $0.50 | $25.00 |
| High-volume run, uneven figures | 12 | $333.33 | 777 | $0.43 | $27.78 |
Read the first two rows together and the point of tracking both rates appears: the team week paid better per hour ($30.00 against $25.00) yet cost more per piece ($0.50 against $0.40), because its pace was slower at 60 pieces per hour against 62.5. A rising hourly rate with a rising per-piece cost usually means output slowed, rework crept in, or downtime was paid but produced nothing. The per-piece bars below make that comparison visual for the same four runs:
Labor cost per piece, four runs
The minimum wage and overtime checks this rate feeds
The hourly rate is a compliance check as well as a pay figure. Piece-rate pay is allowed under the Fair Labor Standards Act only while the worker still receives at least the equivalent of the minimum wage for the hours worked, plus overtime for hours past 40 in a workweek, a rule the U.S. Department of Labor states in its Employment Law Guide on minimum wage and overtime pay. The federal minimum is $7.25 per hour, and many states set a higher one, so compare the hourly result against the rate that applies where the work happens.
Overtime needs one extra step that this tool deliberately does not hide inside its two outputs. Because piece earnings already pay straight time for every hour worked, the regulation adds a half-time premium on the regular rate for each hour over 40. Take a 50-hour week with $600 of piece earnings: the regular rate is $600 ÷ 50 = $12.00 per hour, the premium is 0.5 × $12.00 × 10 overtime hours = $60.00, and the week’s pay is $660.00, not $600.00. Run the week’s totals through the calculator to get the $12.00 regular rate, then add the premium by hand. Payroll that skips this step is the classic piecework violation, and it is why the hourly output matters more than the per-piece one on long weeks. For the labor cost a piece rate creates inside a whole payroll, the direct labor calculator and the labor percentage calculator pick the figures up at the business level.
Two different things are called a wrap rate
Search “wrap rate” and two unrelated calculations collide. This page is the piecework one. The other belongs to government contracting, where a wrap rate is the multiplier that turns a direct labor wage into a fully burdened billing rate after fringe benefits, overhead and general and administrative costs are layered on: a $50 wage at a 2.10 wrap becomes a $105 break-even billing rate before profit. That meaning needs fringe, overhead and G&A percentages as inputs, none of which this tool asks for, because it answers a production question instead.
If you landed here pricing contract labor, the neighbouring tools are the right ones: the loaded labor rate calculator builds the fully burdened hourly figure, and the burden rate calculator works the employer-cost percentage behind it. If you are setting or checking pay per piece on a production line, packing bench or picking route, you are in the right place, and the rest of this article is about that rate.
What competing calculators miss
Tools answering to this keyword split into camps, and each leaves a gap this page closes:
- Government-contracting wrap tools (Calculator City’s wrap rate page and similar): fringe, overhead and G&A percentages wrapped around a base wage. Correct for contract pricing, useless on a production floor: there is nowhere to enter pieces produced, so no per-piece cost ever comes out. The shared name is the whole overlap.
- Single-division piece tools (Calculator Ultra’s piece rate calculator): its headline formula divides total piece pay by hours worked only, which is an hourly rate wearing a piece-rate label. The per-piece figure, the one pricing decisions actually need, is never computed.
- Payroll-system overtime engines (Keka, CheckHQ and similar help-centre calculators): thorough on regular-rate and overtime maths, but built for payroll departments inside a product, with tiers, foreman hours and policy settings between you and a number. Nothing you can run on a phone at the end of a shift.
- The gap this page fills: both divisions side by side from the same three inputs, per-piece cost and hourly rate, plus the output pace that explains why one moved without the other, and the minimum wage and overtime context that tells you whether the hourly figure is even legal to pay as it stands.
Lowering the per-piece rate without cutting pay
A lower WRAP rate is only good news when it comes from pace, not from pay. The arithmetic allows exactly three honest routes, and the checks table shows why: at fixed earnings, more finished pieces in the same hours lowers the per-piece cost; at fixed pieces, fewer paid hours does the same; raising earnings alone raises both rates.
- Cut paid downtime: waiting for materials, machine changeovers and rework are hours in the denominator of one rate and the numerator’s cost in the other. The Quebec labour standards body makes the same point from the worker’s side in its piece work wage guidance: slow supply lines are the employer’s cost problem, not a reason the worker’s hourly equivalent drops below the minimum.
- Count honestly: track finished, accepted pieces only, and keep the period consistent week to week. The Bureau of Labor Statistics builds its manufacturing unit labor cost series on the same discipline, compensation divided by output, in its manufacturing productivity and unit labor costs table; changing what counts as a piece mid-stream breaks every comparison.
- Watch the pair, not one rate: a falling per-piece rate with a falling hourly rate means pay was squeezed. A falling per-piece rate with a steady or rising hourly rate means the work genuinely got faster, which is the only version that lasts.
Frequently asked questions
In the piecework sense used on this page, the WRAP rate is the total earnings for a run of work divided by the pieces produced: the labor cost or pay attached to each finished unit. $200 of earnings for 500 pieces is a WRAP rate of $0.40 per piece.
The WRAP rate divides earnings by pieces, so it measures cost per unit of output. The hourly rate divides the same earnings by hours worked, so it measures pay per unit of time. A worker can earn more per hour while costing more per piece if their pace slows, which is why the calculator reports both.
Yes. Add the team’s hours together, add their earnings together, and enter the team’s total pieces. The results are the team’s average per-piece and per-hour rates, which is the right level for pricing a job or comparing production runs, though it hides differences between individual workers.
Only if you put them in. The calculator divides whatever figure you enter as earnings, so entering labor cost alone gives a labor-only rate, while entering labor plus materials gives a loaded per-piece cost. For a rate you can compare week to week, enter labor only and keep the convention fixed.
Compare the hourly rate result with the minimum wage that applies where the work is done. Piece-rate pay is permitted only while the worker still receives at least the minimum wage equivalent for the hours worked, so if the hourly result falls below that floor, the employer has to top the pay up to the floor.
No. The hourly rate it returns is the regular rate for the period you enter. For a workweek over 40 hours, federal rules for pieceworkers add a half-time premium: half the regular rate for each hour past 40. On a 50-hour week earning $600, the regular rate is $12.00 and the extra premium is $60.00, for $660.00 total.
Zero earnings return $0.00 rates, which describes unpaid work. The tool also passes a negative earnings figure through and shows a negative rate, which in practice means the figures describe a loss rather than a wage. Hours and pieces, by contrast, must be greater than zero or the tool asks for valid positive values.
No. In government contracting, a wrap rate is the multiplier that loads fringe, overhead and general and administrative costs onto a direct labor wage to produce a fully burdened billing rate. This calculator is the piecework tool: earnings per piece and per hour from production figures. The two share a name and nothing else.
