How do you calculate service contract margin?

Subtract delivery cost from contract revenue, divide by revenue, and multiply by 100. With $18,000 of delivery cost on $32,000 of revenue, margin is (32000-18000)/32000 x 100 = 56.25%.

What is a good margin on a service contract?

Calibration and instrument service contracts commonly target 35 to 50% gross margin to absorb travel, loaners and unplanned calls. The 56.25% in this example is strong, sitting 16.25 points above a 40% target.

Why is my gap to target negative when margin beats target?

In this calculator the gap is actual margin minus target, so a positive number means you are above target. The example shows actual 56.25% against a 40% target; the relationship is a 16.25-point surplus over target.

What costs go into service delivery cost?

Technician labor and travel, loaner or replacement instruments, calibration standards usage, consumables, shipping and a share of overhead. Leave out anything already counted elsewhere to avoid double-costing.

Should I price contracts on margin or markup?

Margin is the safer lens because it is a share of revenue. A 56.25% margin equals a 1.78x markup on cost; quoting on markup alone can hide how thin the revenue cushion really is when calls spike.

How do I use the gap to target?

Treat it as a pricing dial. A positive gap means room to compete on price or absorb risk; a negative gap means you must raise the fee, cut delivery cost, or walk away from the renewal.

Measurement, Test & Control Equipment calculator

Test Equipment Service Contract Margin Calculator

Service contract margin is the gross profit percentage you earn on a calibration, repair or instrument-maintenance service agreement after the cost of delivering it. Service managers and contract owners in the test-and-measurement world use it to price annual agreements, decide which contracts to renew, and spot deals that look busy but barely break even. It matters because field service and calibration contracts carry hidden delivery cost — technician travel, loaner instruments, consumables — that erodes margin fast. This calculator shows both the margin you are actually earning and how far it sits from your target.

What this calculator does

Calculate the gross margin on your test equipment service contract by comparing contract revenue against your estimated service delivery cost. Determine if your service pricing covers labor, parts, calibration, and travel expenses.
Use when pricing service contracts for test and measurement equipment, reviewing margin on existing service agreements during renewal, or evaluating whether to offer extended warranty or full-service coverage.
It computes gross margin as the percentage of contract revenue left after service delivery cost, plus the gap in points to your target margin.

Formula used

Service contract margin = (contract revenue - service delivery cost) / contract revenue x 100
Gap to target = actual margin - target gross margin

Inputs explained

Estimated annual service delivery cost:
Annual service contract revenue:
Target gross margin:

How to use the result

Use it when pricing a new service agreement, reviewing renewals, or screening a portfolio of contracts for underperformers.
It uses one annual cost figure and ignores cash-flow timing, warranty exposure and scope creep, so a healthy headline margin can still erode if call volumes run above plan.
