How do you calculate capacity gap for a supplement line?

Multiply output per day by available days to get gross capacity, then multiply that by uptime and yield. At 50,000 units/day over 20 days, gross is 1,000,000 units; at 85% uptime and 96% yield you get 816,000 good units, a gap of 184,000.

What is the difference between gross capacity and good capacity?

Gross capacity is the theoretical output if the line ran every scheduled minute with zero rejects (1,000,000 units here). Good capacity is what passes QA and ships after downtime and yield losses (816,000 units).

What is a good uptime for a tablet or capsule line?

Well-run solid-dose lines run 80-90% uptime against scheduled time; 85% is a realistic planning figure. Below 75% usually signals changeover or feed-system problems worth investigating.

How much capacity is lost to yield versus downtime?

In this example downtime removes 150,000 units (the larger loss) and yield removes another 34,000 units from the post-downtime base, for 184,000 total lost. Downtime is usually the bigger lever in nutraceuticals.

Should I plan production at gross or good capacity?

Always plan against good capacity. Committing to gross capacity overstates output by roughly 18% in this case and is the fastest way to short a customer.

Does this account for QA release time?

No. Good capacity is units that pass yield checks, but they still sit in quarantine until QA releases the batch. Pair this with a QA release-time calculation for true available-to-ship volume.

Nutraceuticals & Functional Foods calculator

Capacity Gap Calculator

Capacity Gap tells a nutraceutical or functional-food plant how many saleable units a line will actually deliver over a planning window once downtime and yield losses are taken out of the theoretical maximum. Nameplate capacity always overstates what ships, because tablet presses, encapsulators, and powder blenders lose time to changeovers, CIP cycles, and metal-detector rejects. Production planners and operations managers use this to commit realistic volumes to sales, size safety stock, and decide whether a contract fits inside existing lines or needs overtime. Treating gross capacity as real capacity is the single most common cause of missed shipment dates in this sector.

What this calculator does

Estimate the good production capacity available over a period so planners can compare it against demand and see the capacity gap before committing.
A planner needs the realistic good output a process can deliver over a period to compare against demand and size any capacity shortfall.
It computes good sellable units as gross capacity multiplied by expected uptime and expected yield, and splits out the units lost to each.

Formula used

Gross capacity = output per production day × available production days
Good capacity available = gross capacity × expected uptime × expected yield

Inputs explained

Output per production day:
Available production days:
Expected line uptime:
Expected first-pass yield:

How to use the result

Use it during S&OP commitments, contract-manufacturing quoting, or any time you must promise a volume against a fixed number of production days.
It applies single average uptime and yield figures, so it will not capture line-specific bottlenecks, SKU mix effects, or batch-record hold time before QA release.

Current U.S. benchmarks

Industrial natural gas averages $4.9 per Mcf (EIA, Apr 2026), down 7.7% from a year earlier, with industrial electricity at 8.66 cents per kWh. Process heating and refrigeration budgets track both.
The U.S. has 31,130 food manufacturing establishments employing about 1,707,316 workers (Census County Business Patterns, 2023).
