How do you calculate string setup labor?

Divide the setup queue by instruments set up per minute for base time, then multiply by one plus the bench allowance. For 120 instruments at 12 per minute, base time is 10 hours and a 10% allowance gives 11 hours.

Why add a bench allowance?

Raw setup rate ignores restrings, retests, and second passes on instruments that don't settle the first time. The allowance — 10% here — turns 10 base hours into the 11 bench hours the work really takes.

What counts as a string setup?

Typically stringing, truss-rod and neck-relief adjustment, action and intonation at the saddle, nut check, and a play test. Heavier work like fret leveling should be timed separately, not folded into this rate.

What is a good setup throughput?

It depends on instrument type and how dialed-in the necks arrive. Use your own timed rate rather than a generic figure; a guitar setup and a 12-string or floating-bridge archtop are not the same job.

Setup labor vs machine time — what's different here?

Setup is skilled hand labor with no machine to share across operators, so these hours map almost directly to bench-tech hours, unlike spindle time which one operator can tend across machines.

How do I size the bench allowance for a tough batch?

Track how often instruments need a restring or a second pass and express it as a percentage of clean setups. New-neck batches that need settling time often justify well above 10%.

Instrument String Setup Labor Calculator

String setup labor estimates the bench hours needed to do final setup on a queue of instruments — stringing, truss-rod and neck-relief adjustment, action and intonation, and a play test. Repair shops, custom builders, and OEM final-inspection lines use it to staff the setup bench, quote batch setups for dealers, and keep the final stage from becoming the chokepoint that delays ship dates. It adds a bench allowance on top of raw setup rate to cover restrings, retests, and the instruments that need a second pass. This stage is labor-intensive and skilled, so estimating it accurately protects both ship dates and quoted prices.

What this calculator does

Estimate the labor hours to string, intonate, and complete final setup on a batch of guitars, basses, or other stringed instruments before they ship.
Use it when the setup bench is taking on a batch and you need a defensible labor estimate for stringing, action setting, intonation, and play test.
It converts a setup queue and a per-instrument setup rate into base bench hours, then adds a bench allowance to give required setup labor hours.

Formula used

Base string setup labor = instruments in setup queue ÷ instruments setup per minute
Required string setup labor = base string setup labor × allowance factor

Inputs explained

Instruments in setup queue:
Instruments setup per minute:
Bench allowance:

How to use the result

Use it to staff the setup bench or quote a dealer batch setup before committing a ship date that depends on final setup throughput.
A single instruments-per-minute rate flattens the difference between a quick restring and a full fret-level-and-setup; segment by setup type when the mix varies.
