Cell Therapy & Gene Therapy Equipment calculator

Single-Use Kit Cost Calculator

Single-use kit cost is the fully loaded consumable spend for the pre-sterilized, closed-system disposables a cell or gene therapy process burns through every run — tubing sets, cartridges, bags, filters and connectors. Autologous CGT processes run almost entirely on single-use to avoid cross-contamination between patient lots, so disposables can be 30-50% of cost of goods. Process development engineers, MSAT teams and CDMO finance leads use this number to set per-batch transfer prices, build CapEx-vs-disposable trade studies, and decide whether to dual-source a kit. Because each run consumes a fresh kit, even a small per-run price change compounds fast across a campaign.

What this calculator does

  • Estimate disposable tubing set, bag, cartridge, filter, and closed-processing kit cost for a batch or campaign.
  • a procurement or manufacturing team is costing single-use assemblies for a patient batch, donor lot, or vector campaign
  • It computes total single-use consumable cost by multiplying runs by per-run kit price and your program allocation, then adding fixed qualification, freight or safety-stock charges.

Formula used

  • Allocated disposable kit cost = runs using the kit × single-use kit cost per run × program allocation
  • Total single-use kit cost = allocated disposable kit cost + fixed qualification, freight, or safety-stock cost

Inputs explained

  • Processing runs using the single-use kit:
  • Single-use kit cost per run:
  • Kit cost allocated to this program:
  • Fixed qualification, freight, or safety-stock cost:

How to use the result

  • Use it when quoting a manufacturing campaign, modeling cost of goods for a process, or evaluating a kit price change or alternate supplier.
  • It assumes one kit per run at a single price and excludes scrap from failed setups, expired stock and reagent fill costs, which can add 5-15% in practice.

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).
  • Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).

Common questions

  • How do you calculate single-use kit cost for a cell therapy campaign? Multiply the number of processing runs by the kit cost per run, scale by the share of kit cost charged to your program, then add fixed qualification, freight and safety-stock charges. For 30 runs at $4,200, 100% allocated, plus $8,000 fixed, that is $126,000 + $8,000 = $134,000 total.
  • Why are single-use kits so expensive in CGT? Closed, gamma-irradiated, animal-origin-free assemblies are custom-welded, individually QC-released and traceable per lot. That sterility and traceability premium is the price of avoiding line clearance and cross-contamination risk in patient-specific manufacturing.
  • What is a good single-use kit cost per run? It varies by platform — viral vector and autologous CAR-T kits commonly run $2,000-$8,000 per run. In the worked example the effective loaded cost is $4,467 per run once the $8,000 fixed charge is spread across 30 runs.
  • Single-use vs stainless steel — which is cheaper? Single-use wins at low-to-mid volume and high product mix because it eliminates CIP/SIP, cleaning validation and changeover downtime. Stainless typically wins only at sustained high volume on a single product, where per-run disposable spend overtakes amortized hardware.
  • How does program allocation affect the result? Allocation is the percent of total kit spend charged to this program when a kit or safety-stock pool is shared. At 100% the full $126,000 lands here; at 60% only $75,600 of the variable spend would be allocated before adding fixed costs.
