Walmart WFS storage fee calculator
This WFS fee calculator works out what your Walmart Fulfillment Services stock costs to store this month and how that changes as it ages. Since Jun 30, 2026, WFS inventory stored 366 to 450 days costs $2.25 per cubic foot a month and $7.50 after 450 days. From October to December, inventory stored more than 30 days carries an extra $1.50 per cubic foot. Enter your units by age to see this month's bill and when removing or disposing of slow stock costs less than keeping it.

An open question, stated plainly. Walmart's page lists the long-term rates by age band but does not say whether they replace the $0.75 standard rate or add to it. This calculator treats them as replacing it, which matches one public worked example (OneCart's WFS fee calculator, vendor). If Walmart confirms otherwise, we will change the tool and log it in the seller rule tracker the same day.
The formula and method
- Monthly fee = Σ over age bands (units × cubic feet per unit × band rate), where the band rate is $0.75 up to 365 days, $2.25 for 366 to 450 days and $7.50 over 450 days
- Peak add-on (October to December) = units stored more than 30 days × cubic feet per unit × $1.50
- Disposal cost = units × disposal fee per unit
- Removal cost = units × (disposal fee + $0.40 × weight in lb)
- Months until removal is cheaper = removal cost ÷ monthly fee at the next band
Worked example
Illustrative · sample figures. 300 units at 0.5 cubic feet each, 150 cubic feet in total, each unit weighing 1 lb.
| Situation | Calculation | Monthly fee |
|---|---|---|
| November, 200 days old | 150 × ($0.75 + $1.50) | $337.50 |
| Outside October to December, 400 days old | 150 × $2.25 | $337.50 |
| Outside October to December, 460 days old | 150 × $7.50 | $1,125 |
| October to December, 400 days old | 150 × ($2.25 + $1.50) | $562.50 |
| October to December, 460 days old | 150 × ($7.50 + $1.50) | $1,350 |
Disposal of all 300 units costs $105 (300 × $0.35). Removal costs about $225 (300 × ($0.35 + $0.40)). At 460 days, one month of storage costs five times the removal cost, so slow stock should leave well before day 450 unless it is about to sell.
Limitations
- The long-term reading follows the interpretation above until Walmart confirms it.
- Age is per unit from receipt; enter your own age bands from Seller Center reports.
- It covers storage, removal and disposal only. Fulfillment fees are in the fee and margin calculator.
- Removal shipping is estimated from weight; your actual cost depends on the destination.
Under every result: this estimate uses the figures you enter and published rates. It is not an audit, an offer or a promise of savings, sales or profit.
What is the WFS long-term storage fee?
From Jun 30, 2026, Walmart charges $2.25 per cubic foot a month for WFS inventory stored 366 to 450 days and $7.50 for inventory stored more than 450 days (Walmart Marketplace Learn, updated May 27, 2026).
What does WFS charge in the fourth quarter?
From October to December, inventory stored more than 30 days carries an extra $1.50 per cubic foot a month on top of the storage rate. Stock sent in Q4 that sells within 30 days avoids it.
Is it cheaper to remove or dispose of old WFS stock?
Disposal costs $0.35 a unit up to 2 lb; removal adds $0.40 per lb for shipping. Once stock passes 450 days, a single month of storage can cost more than removing it.
