Quick answer: Amazon FBA storage fees in 2026 cost $0.78 per cubic foot for standard-size inventory from January through September, rising to $2.40/cu ft during the October-December peak season. Oversize rates run $0.56/cu ft off-peak and $1.40/cu ft in Q4. A 6-month long-term surcharge kicks in after 181 days of storage.

Managing seasonal inventory on Amazon FBA is a science of timing. Send too early and you pay months of elevated storage fees. Send too late and you miss the Q4 sales window entirely. This guide covers the 2026 Amazon holiday peak fees, storage fee schedules, and strategies to maximize your Q4 profit.
Key fact: Amazon FBA standard-size storage fees in 2026 run $0.78 per cubic foot from January to September and jump to $2.40 per cubic foot for the October-December peak (oversize from $0.56 per cubic foot), and 6-month-plus aged inventory adds steep monthly surcharges, so shipping Q4 stock early or holding slow SKUs can erase the margin.

Amazon's 2026 peak season is two overlapping windows, not one. The fulfillment peak runs October 15, 2026 through January 14, 2027; the monthly storage peak runs October 1 through December 31 and reverts to the off-peak rate on January 1. The overlap is roughly 2.5 months. Here's what to expect:
| Fee Type | Standard Rate (Jan-Sep) | Peak Rate | Change |
|---|---|---|---|
| Fulfillment Fee (Standard) | $3.22 - $3.86 | $3.54 - $4.25 | +$0.32 |
| Fulfillment Fee (Large) | $4.95 - $6.50 | $5.45 - $7.15 | +$0.50-$0.65 |
| Storage Fee (Standard) | $0.78/cu ft | $2.40/cu ft | +208% |
| Storage Fee (Large) | $0.56/cu ft | $1.40/cu ft | +150% |
| Storage Fee (Special) | $0.84/cu ft | $2.40/cu ft | +186% |
Peak windows differ by fee type: fulfillment peaks Oct 15 – Jan 14, monthly storage peaks Oct 1 – Dec 31 (reverts Jan 1). Storage rates are per cubic foot per month; fulfillment rates are per unit.
Amazon's 6 month inventory storage charge is not a fee you opt into — it is the aged inventory surcharge, formerly the long-term storage fee (LTSF). Any unit that has spent 181 days or more in a fulfillment centre starts attracting it, on top of the standard monthly storage fee. From day 181 holding stock stops being cheap: the surcharge alone runs from $0.50 per cubic foot per month up to $7.90 at 456+ days — roughly 1.6x to 11x the base rate of $0.78/cu ft for standard-size items.
Two changes in 2026 catch sellers who are still working from older guides:
The full 2026 ladder, and what each rung costs relative to plain storage:
| Inventory age in FBA | Aged surcharge per cu ft / month | Total vs base storage rate |
|---|---|---|
| 0–180 days (under six months) | $0 — standard storage only | 1x |
| 181–210 days | $0.50 | 1.6x |
| 211–240 days | $1.00 | 2.3x |
| 241–270 days | $1.50 | 2.9x |
| 271–300 days | $5.45 | 8.0x |
| 301–330 days | $5.70 | 8.3x |
| 331–365 days | $5.90 | 8.6x |
| 366–455 days | $6.90 (or $0.30/unit, whichever is higher) | 9.8x |
| 456+ days | $7.90 (or $0.35/unit, whichever is higher) | 11.1x |
Two rules that catch sellers out. First, the 181–270 day bands exclude clothing, footwear, bags, jewellery and watches — for those categories the surcharge does not start until 271 days, so the band that applies to your SKU depends on its category as well as its age. Second, on the 366–455 and 456+ bands Amazon charges the greater of the per-cubic-foot rate and the per-unit minimum, so a per-cubic-foot-only model understates small items stored that long.
The multiplier column uses the $0.78 per cu ft standard-size rate for January–September 2026. In Q4 the base rate triples to $2.40, which is why aged stock held through peak season is the single most expensive inventory mistake in FBA.
One standard-size SKU, 200 units, 1 cubic foot each = 200 cu ft. You stop promoting it in March and let it sit:
| Month held | Inventory age | Base storage | Aged surcharge | Month total |
|---|---|---|---|---|
| Months 1–6 | 0–180 days | $156 | $0 | $156 |
| Month 7 | 181–210 days | $156 | $100 | $256 |
| Month 8 | 211–240 days | $156 | $200 | $356 |
| Month 9 | 241–270 days | $156 | $300 | $456 |
| Month 10 | 271–300 days | $156 | $1,090 | $1,246 |
| Month 11 | 301–330 days | $156 | $1,140 | $1,296 |
Six clean months cost $936 in base storage. Month 7 adds $100 of surcharge on top. By month 10 a single month's bill — $1,246 — exceeds everything you paid across the first half-year combined. That curve, not the headline storage rate, is what makes a reorder cycle under six months worth designing for.
Check the aged surcharge on a specific product with the 6-month inventory storage fee calculator, or compare every fee line in the Amazon FBA fee reference.
Storage fees are the biggest seasonal cost shock. Here's a practical comparison:
| Product Size | Monthly Storage Cost (Q3) | Monthly Storage Cost (Q4) | 6-Week Q4 Cost |
|---|---|---|---|
| Small item (0.5 cu ft) | $0.39 | $1.20 | $1.80 |
| Medium item (1 cu ft) | $0.78 | $2.40 | $3.60 |
| Large item (2 cu ft) | $1.56 | $4.80 | $7.20 |
| Pallet (12 cu ft) | $9.36 | $28.80 | $43.20 |
Strategy: Use the Holiday Peak Fees Calculator to model your exact costs before sending inventory to FBA.
Monthly storage is billed per cubic foot per month, based on the average daily volume your inventory occupied in a fulfilment centre that month. It is not a one-off charge at inbound. The clock starts the month units are received and become available for sale, and it runs monthly from then on — which is why three SKUs with identical dimensions can produce three different bills.
There is no free window at the base rate. What actually changes is which of three regimes a unit sits in:
| Regime | Trigger | Rate (standard-size, per cu ft / month) |
|---|---|---|
| Short-term (base storage only) | Day 1 to day 180 | $0.78 (Jan–Sep) · $2.40 (Oct–Dec) |
| Long-term (base + aged surcharge) | Day 181 onwards | Base rate + $0.50 up to $7.90, billed in bands |
| Removal or disposal | Any time you choose | One-off per-unit fee, after which storage cost stops |
Short-term means under six months: you pay the base monthly rate and nothing else. Long-term means 181 days or more, when the aged inventory surcharge is added on top of that base rate. The bands are not linear. Between day 181 and day 270 the surcharge runs from $0.50 to $1.50 per cubic foot; at day 271 it jumps to $5.45. The cliff is day 271, not day 181 — which is why a SKU that looks manageable at seven months can become the most expensive inventory you own by month ten.
Two scheduling facts matter more than the rate itself:
Because the aged bands are assessed monthly, the real decision is rarely "remove this SKU or hold it forever" — it is "what does one more month cost, versus the removal fee?" Run that comparison at day 150, while you still have two weeks before the next snapshot. For a slow-moving SKU the payback on a removal is usually a single month.
| Date | Event | Action Required |
|---|---|---|
| Oct 1 | Storage peak begins — $2.40/cu ft (3.08x off-peak) | Stop shipping non-seasonal inventory |
| Sep 1 | Inventory performance review | Ensure IPI > 400 to avoid storage limits |
| Sep 15 | Ocean freight cutoff for Oct delivery | Last safe date for sea shipments from Asia |
| Oct 1 | Holiday inventory should be in FBA | Last safe date before carrier delays |
| Oct 10-12 | Prime Big Deal Days | First peak sales event — test pricing |
| Oct 15 | Peak fee season begins | All storage/fulfillment fees increase |
| Nov 1 | Black Friday inventory cutoff | All Q4 inventory must be received |
| Nov 15 | Peak fulfillment season | Sales volume accelerates 3-5x |
| Nov 28 | Black Friday | Peak sales day |
| Dec 1 | Cyber Monday | Second peak sales day |
| Dec 15 | Last FBA delivery guarantee | After this, shipping may miss Christmas |
| Dec 26 - Jan 14 | Post-holiday return wave | Return rates spike 30-50% |
| Jan 1 | Storage peak ends | Monthly storage reverts to $0.78/cu ft |
| Jan 14 | Fulfillment peak ends | Fulfillment fees return to the standard rate on Jan 15 |
Introduced in 2024, the Low-Inventory-Level fee penalizes sellers who don't maintain adequate stock. During peak season, this fee is particularly dangerous because demand spikes can quickly deplete inventory.
| Historical Days of Supply | Fee per Unit (Standard) | Fee per Unit (Large) |
|---|---|---|
| 28-21 days | $0.32 | $0.43 |
| 21-14 days | $0.52 | $0.69 |
| 14-7 days | $0.68 | $0.90 |
| Below 7 days | $0.89 | $1.18 |
⚠ Risk Warning: Over-ordering seasonal inventory is the #1 cause of Amazon seller failure. Order for 70% of your optimistic forecast. You can always reorder if you sell out. You cannot return 3,000 units of unsold holiday inventory.
Use this formula to estimate your total Q4 FBA costs per unit:
Example: A 1-cu-ft product selling for $29.99 in Q4:
| Referral Fee (15%) | $4.50 |
| Fulfillment Fee (standard) | $3.86 |
| Storage Fee (6 weeks) | $3.60 |
| Low-Inventory Fee (est.) | $0.52 |
| Total Q4 Cost | $12.48 (41.6% of sale price) |
| vs Q3 Cost (same product) | $10.01 (33.4%) |
| Q4 Margin Reduction | -$2.47 per unit (-8.2%) |

Amazon's aged inventory surcharge — formerly the long-term storage fee (LTSF) — now starts at 181 days in a fulfillment center, down from 271 days in 2025. Unlike the old twice-a-year check, it is assessed every month (inventory snapshot on the 15th, charge posts between the 18th and 22nd). It stacks on top of standard monthly storage, which runs $0.78/cu ft (Jan–Sep) and $2.40/cu ft (Q4 Oct–Dec) for standard-size items.
| Inventory age in FBA | Surcharge per cu ft / month |
|---|---|
| 0–180 days | $0 (standard storage only) |
| 181–210 days | $0.50 |
| 211–240 days | $1.00 |
| 241–270 days | $1.50 |
| 271–300 days | $5.45 |
| 301–330 days | $5.70 |
| 331–365 days | $5.90 |
| 366–455 days | $6.90 (or $0.30/unit, whichever is higher) |
| 456+ days | $7.90 (or $0.35/unit, whichever is higher) |
The practical takeaway: inventory older than 6 months costs roughly 1.6x–10x your base storage rate, so liquidation, removal, or tighter reorder cycles almost always beat holding aged stock through Q4.
Amazon holiday peak fees 2026 include standard FBA referral fees (8-15%), elevated fulfillment fees, and tripled Q4 storage fees ($2.40/cu ft vs $0.78/cu ft standard). Low-Inventory-Level fees ($0.32-$0.89/unit) also apply when stock falls below 28 days of supply. Peak season runs Oct 15 - Jan 14.
FBA storage fees triple during Q4 peak season. Standard-size items go from $0.78/cubic foot (Jan-Sep) to $2.40/cubic foot (Oct-Dec). Large items go from $0.56 to $1.40. A pallet costing $9/month in July costs $28.80/month in November.
Send holiday inventory to FBA by October 1st for the safest delivery window. Late shipments (after Nov 1) face longer receiving times (up to 30 days) and may miss Black Friday/Cyber Monday sales.
The Low-Inventory-Level fee applies when your inventory falls below 28 days of supply. It ranges from $0.32-$0.89 per unit. During peak season, maintain at least 30-45 days of supply to avoid this fee.
Total Q4 FBA costs = Referral fees (8-15%) + Fulfillment fees (per unit) + Storage fees ($2.40/cu ft × weeks ÷ 4) + Low-Inventory fees ($0.32-$0.89 if applicable). Use our free Holiday Peak Fees Calculator for exact estimates.
Amazon starts charging monthly storage from the month your units are received and become available for sale — there is no free holding period at the base rate. What changes at six months is not whether you pay, but how much: from day 181 the aged inventory surcharge is added on top. Amazon takes the inventory-age snapshot on the 15th of each month and posts the charge between the 18th and the 22nd, so act by the 1st if you want to clear stock before a billing cycle.
Short-term storage is inventory under 180 days old in a fulfillment centre. It is billed at the base monthly rate only — $0.78/cu ft for standard-size units in Jan–Sep, $2.40/cu ft in Oct–Dec — with no aged surcharge. Long-term storage begins at day 181, when the aged inventory surcharge stacks on top of that base rate. Keeping the reorder cycle under six months is the only durable way to stay in the short-term regime.
