How do you calculate compression pack rate?

Divide the mattresses you compressed and packed by the total scheduled, then multiply by 100. With 92 packed out of 100 scheduled, the rate is 92%.

What is a good compression pack rate?

Mature bed-in-a-box lines run 95-98% against schedule. Our example hits 92%, leaving a 3-point gap to the 95% target — recoverable, but worth a root-cause look at downtime or carton supply.

Why is my pack rate below target even when the line ran all shift?

Running isn't the same as packing to plan. Compression press jams, carton shortages, foam not fully cured, and changeovers between sizes all eat into the count without stopping the clock.

Does mattress size affect the pack rate?

Yes. A king or hybrid takes more compression dwell time than a twin, so a size-heavy schedule lowers achievable throughput even when operators never slow down.

How is pack rate different from line efficiency?

Pack rate measures output against the schedule; line efficiency measures output against the theoretical cycle-time capacity. You can be 100% efficient on a deliberately short schedule and still miss the day's plan.

What gap to target should trigger action?

A 1-2 point gap is normal noise. The example's 3-point gap is a yellow flag; sustained gaps above 5 points usually mean a structural issue like an undersized compression press for the size mix.

Mattress, Bedding & Foam Product Assembly calculator

Compression Pack Rate Calculator

Compression pack rate measures what share of your scheduled mattresses actually made it through the roll-pack line — compressed, rolled, boxed, and ready to ship — within the run. Production supervisors and plant managers on bed-in-a-box lines track it shift by shift because every uncompressed unit ties up floor space, a flat-pack carton, and a freight slot. A line humming at target keeps the warehouse fed and trucks loaded; a line drifting below it quietly builds a backlog of loose mattresses no one budgeted for. It is the cleanest single number for telling whether your compression cell kept pace with the build schedule.

What this calculator does

Calculate the effective completion rate of your compression roll-pack line, comparing actual packed units against the shift schedule to track on-time performance.
Use this when tracking bed-in-a-box production schedule adherence, comparing compression machine capacity to assembly output, or evaluating capital investment in faster roll-pack equipment.
It computes the percentage of scheduled mattresses that were compressed and packed, plus the point gap to your target rate.

Formula used

Actual pack rate (%) = mattresses compressed ÷ total scheduled × 100
Gap to target = target pack rate - actual pack rate

How to use the result

Use it at shift end or run end to verify the compression cell kept up with the build plan and to flag short-falls before they hit shipping.
It treats every mattress as one unit, so it won't reflect that a king takes far longer to compress than a twin — mix shifts can distort the rate.

Current U.S. benchmarks

The producer price index for plastic resins and materials stands at 319.371 (BLS, May 2026), up 19.5% from a year earlier. Quotes priced off last quarter's material cost miss this move.
Manufacturing hourly earnings average $30.27 (BLS, Jun 2026), up 4.4% from a year earlier. Median machinist pay is $28.24/hr (OEWS 2025), with state medians on each state page. Manufacturers have 529k open positions nationally (BLS JOLTS).
