How do you calculate tooling storage cost?

Multiply storage months by the monthly slot rate and by occupancy share, then add the preservation and handling fee. For 24 months at $45/month, 100% occupancy, and a $300 fee: 24 x 45 x 1.0 + 300 = $1,380.

What does the occupancy share represent?

It is the fraction of a full storage slot the tool actually consumes. At 100% the tool fills a dedicated slot; a small fixture sharing a rack might be 50%, halving the variable storage charge.

Is it cheaper to store tooling or re-cut it later?

Compare the total storage cost to the rebuild quote. If two years of storage runs $1,380 but re-cutting the die costs $30,000, storage is clearly the economical hold; the balance flips only for cheap, easily reproduced tooling.

What is a typical monthly slot rate for stored tooling?

In-house racked storage often runs $20-$60/month per slot fully burdened; third-party climate-controlled tooling storage can exceed $100/month. The $45/month default reflects mid-range in-house racking.

Why separate the preservation fee from the monthly rate?

Rust-preventive coating, wrapping, and initial handling are one-time events that do not recur monthly. The $300 fee is a fixed adder, keeping the $1,080 variable slot cost cleanly time-proportional.

How do I get cost per month of storage?

Divide the total by the number of months. Here $1,380 over 24 months is $57.50 per month all-in, which is higher than the $45 slot rate because it spreads the one-time preservation fee across the term.

Tooling, Fixtures, Dies & Mold Economics calculator

Tooling Storage Cost Calculator

Tooling storage cost is the often-invisible carrying charge for dies, molds, and fixtures that sit idle between production runs. Operations managers and tooling asset owners use it to decide whether to keep dedicated tooling on the shelf, ship it back to a customer, or scrap it. Racking, climate control, corrosion protection, and periodic handling all accrue whether or not the tool ever runs again. Quantifying it turns a fuzzy overhead line into a number you can weigh against re-cutting the tool later.

What this calculator does

Estimate the cost of warehousing idle tooling, combining a monthly slot charge with one-time preservation and handling fees.
A supply chain planner uses it to price the carrying cost of inactive molds and dies held against future service or repeat orders.
It computes the total holding cost of stored tooling by loading storage months against a monthly slot rate at an occupancy share, then adding a one-time preservation and handling fee.

Formula used

Storage cost = months x monthly slot rate x occupancy share% + preservation fee
Cost per month = total storage cost / months

Inputs explained

Storage Duration:
Monthly Slot Rate:
Occupancy Share:
Preservation & Handling Fee:

How to use the result

Use it during storage-vs-scrap reviews, customer tooling-ownership audits, or annual inventory carrying-cost analysis.
It does not price the risk of tool degradation or obsolescence, nor the opportunity cost of the floor and rack space beyond the quoted slot 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.
The U.S. has 14,378 furniture and related products establishments employing about 355,594 workers (Census County Business Patterns, 2023).
