How to use this calculator
- Enter your numbers in each field above — the calculator updates instantly as you type, so there's nothing to submit.
- Use your real figures when you have them, or sensible estimates while you're planning. If a field doesn't apply, leave it at zero.
- Compare the results, then change one input at a time to see how each lever (price, cost, fees, volume) moves the outcome.
Formula
Cash tied up = Unsold × Cost + Storage · Recovery = Unsold × Discount price · Loss = Cash tied up − Recovery
Worked example
40 unsold at $8 cost, $50 storage, $9 discount price.
- Cash tied = 40 × 8 + 50 = $370
- Recovery = 40 × 9 = $360
- Loss = $10
Answer: $370 tied up; discounting recovers $360
How it works
Dead stock has an ongoing cash cost, not a fixed loss. The longer you sit on it, the higher storage adds — usually cheaper to discount aggressively and free the cash than to protect a margin that won't materialize.
How to interpret your results
- Dollar values are shown per sale, per order, or per item unless a result is explicitly labelled monthly, weekly, or daily.
- Percentages (margin, ROI, conversion rate) are easier to compare across products and price points than raw dollars — use them when you benchmark.
- A positive result means you're ahead after the costs and fees you entered. A negative result means the current numbers don't work — change a lever (raise price, cut a cost, lower ad spend) and recalculate.
- Treat the output as a planning estimate, not a guarantee. Fees, taxes, and conversion rates shift over time — re-run the numbers whenever a key input changes.
Common mistakes
- Waiting for full-price sales that won't happen.
- Forgetting storage cost — it accumulates monthly.
- Discounting below cost without checking recovery math.

FAQ
- When should I discount dead stock?
- If sell-through hasn't moved in 60–90 days and storage is meaningful, discount to recover cash. Cash usually beats gross margin.
- How is this different from Sell-Through Rate?
- Sell-through measures inventory movement. Dead Stock Cost quantifies the money trapped in items that aren't moving.
