How do you calculate AR coating cost?

Multiply lenses by per-lens cost and by AR batch share for the variable cost, then add fixed setup. For 520 lenses at $6.75, 100% AR share, plus $480 setup, variable is $3,510 and total is $3,990.

What is the true per-lens AR coating cost?

Divide total cost by lenses coated. In the default case $3,990 over 520 lenses is about $7.67 per lens — higher than the $6.75 variable rate because the $480 setup spreads across the batch.

Why does AR cost per lens fall with larger batches?

The $480 fixed setup is the same per chamber run regardless of count. Coat 520 lenses and it adds $0.92/lens; coat 1,000 and it adds about $0.48/lens, pulling the loaded cost toward the variable rate.

What batch share should I enter for AR coating?

Use the percent of the batch actually getting AR. If only part of a mixed run is AR, set it below 100% so variable cost reflects only coated lenses; the default 100% assumes the whole batch is AR.

Should AR scrap be included in coating cost?

Build expected scrap into your per-lens rate or coat extra to net your target good count. AR delamination and cosmetic rejects are real, so a bare consumable cost understates true loaded cost.

AR coating cost vs outsourcing — how do I compare?

Compare the loaded per-lens figure (here $7.67, including setup) against the vendor's all-in price plus freight and turnaround. In-house only wins clearly when batch sizes dilute setup enough.

AR Coating Cost Calculator

AR Coating Cost rolls up what an anti-reflective coating run actually costs, combining the per-lens variable cost with the fixed setup and qualification overhead that a chamber run carries whether you coat 50 lenses or 500. Lab cost estimators and coating-room supervisors use it to quote AR upcharges, decide minimum economical batch sizes and see how the fixed cost dilutes across volume. AR is a high-value, high-scrap-risk process, so getting its true loaded cost right protects margin on premium jobs. The calculator separates variable from fixed cost and reports an effective per-lens figure that includes setup amortization.

What this calculator does

Estimate anti-reflective coating cost for lenses or pairs using coated quantity, cost per lens, scope share, and fixed setup or certification cost.
an estimator needs AR coating cost for a quote or production batch
It computes total AR coating cost as volume times per-lens rate times AR batch share, plus fixed setup, and the resulting average loaded cost per lens.

Formula used

Variable AR coating cost = AR-coated lenses × AR coating cost per lens × batch share with AR coating
Total AR coating cost = variable AR coating cost + fixed AR setup and qualification cost

Inputs explained

Lenses receiving AR coating:
AR coating cost per lens:
Batch share with AR coating:
Fixed AR setup and qualification cost:

How to use the result

Use it to set AR upcharges, find the break-even batch size where setup is acceptably diluted, and compare in-house coating cost to outsourcing.
It models one coating configuration; mixed AR stacks (hydrophobic, mirror, blue-cut) carry different per-lens rates and scrap risks, so run them separately rather than blending.

Current U.S. benchmarks

U.S. manufacturing runs at 75.6% of capacity with new factory orders at $657B per month (Federal Reserve and Census, May 2026).
