What does an order from your store really cost — real calculation, no tricks
Put together all the costs that simple calculators hide from you — salaries, rent per m², utilities, fit-out depreciation, materials at purchase price, your own time. Compare the real figure with a competitor quote and our public prices. All sources linked and verifiable.
They show you only 2–3 cost categories (pick & pack and storage), while the rest appear on the month-three invoice: monthly minimum fee, Q4 peak surcharges, setup fees, address corrections, restocking, hidden courier margin. The calculator below puts together all 9 real cost categories in a logistics operation — and includes a separate mini-calculator to honestly estimate what it really costs to do it in-house (salaries, rent per m², utilities, fit-out depreciation, materials, time). The Fast Fulfill column adjusts automatically to the correct tier. No email, no form, just transparent maths.
Before you use the calculator
4 essential things you need to understand
The calculator below is built to be honest, not to convince you to choose a particular provider. To get a useful result, you need to understand a few basic principles about how the real cost of an eCommerce order is composed. Most calculation errors come from ignoring one of these 4 fundamental realities:
1. The in-house cost is almost always higher than you think
Entrepreneurs typically calculate only the effective time they personally spend packaging. In reality, the complete in-house cost includes 8–10 hidden categories that nobody accounts for: the proportional rent of the space used for storage (even if it's a room at home, it has an opportunity cost), utilities (electricity, heating, internet), packaging materials purchased at retail prices (40–60% more expensive than wholesale), WMS or management software (even an Excel has a maintenance time cost), customer support on delivery (answering "where is my parcel?"), cover for holidays and illness, depreciation of racking and equipment, and the opportunity cost of your own time (see our detailed articles in the guides section).
Our in-house calculator asks you questions you already know the answers to (picker salary, rent per m², minutes per order), then does the maths automatically. For operating hourly cost in Romania 2026, our realistic recommendation is €8–12/h (~40–60 RON/h) for a hired picker and €20/h opportunity cost for an entrepreneur working alone. All suggestions are based on verifiable figures from INS, BestJobs, and Colliers Q4 2025 reports.
2. The competition makes you believe it is cheap through selective display
The vast majority of fulfillment operators display an attractive pick & pack price (€0.80–1.20/order for a small product), but hide in the month-three invoice a long list of fees not mentioned during negotiation: monthly minimum fee (€200–500), Q4 peak season surcharges (+15–30% on normal rates), restocking fees for returns (5–15% of product value), address correction fees (€5–15/parcel for incomplete addresses), technology fees for WMS (€50–200/month), long-term storage penalties after 30–60 days (2–5× normal rate), hidden courier margin (5–15% above the real rate they negotiated with the carrier), and initial setup fees of €500–2,000 for integration and configuration.
Our calculator includes all these lines as editable fields so you can fill them in with the real values from any quote received. If a competitor quote says "just €0.80/order", check what else is on top — then enter the figures here and see the real total.
3. Real prices always change with volume
The real cost of fulfillment is not a single figure, but a curve that decreases as volume grows. At 50 orders/month you pay more per order than at 5,000 orders/month — because the operator amortises fixed costs (receiving, WMS, training) across fewer transactions. Our calculator faithfully reflects this reality: Fast Fulfill prices update automatically across 8 tiers (T1-T8) based on the order volume you enter. See below how the price curve looks for standard envelope packing:
At a volume of 500 orders/month, you pay €0.32/order for envelope packing. At 10,000 orders/month, you pay just €0.27/order — a reduction of almost 16%. For a B2B store shipping 100 orders/month × 20 units/order = 2,000 total units, the applicable tier is T6, not T2 — because the reference volume for B2B is total units dispatched, not the number of orders.
4. The courier is always separate — at any operator
Regardless of whether you choose in-house, a competitor, or Fast Fulfill, courier costs (Sameday, FAN, DPD, GLS, Cargus, UPS, DHL) are contracted directly between you and the carrier. At Fast Fulfill, we do not enter the transport billing flow at all — you hold the direct account, the courier invoices you directly, and your AWB integrates into our WMS. This means total transparency on the courier cost and direct negotiation between you and the carrier. The calculator below excludes the courier cost entirely — all figures are strictly for fulfillment.

Calculator pitfalls
5 common errors this calculator avoids
Our calculator is built to protect you from the typical traps that appear in other fulfillment calculators — especially those displayed by operators who don't want to show you the real total cost. Here is what it avoids:
1. Comparing only on pick & pack
The most frequent error: entrepreneurs compare only the "pick & pack cost" between providers (e.g. €0.61 vs €0.80) and choose based on that single line. In reality, pick & pack typically represents 40–60% of the total cost. The rest comes from receiving, storage, returns, minimum fees, setup fees, barcode labelling, overweight — categories that many calculators omit entirely. Our calculator includes all 9 main + optional categories.
2. Ignoring tier differentiation
Many calculators display a single price without saying which volume it applies to. This means either the displayed price is only for their maximum volume (and you pay more), or for their minimum volume (and you overpay at large volumes). Our calculator clearly displays the auto-detected tier and automatically adjusts all prices when you change volume.
3. Underestimating picking for multi-product orders
For a store selling complementary products (e.g. cosmetics where customers buy in bundles of 3–4 products), the real picking cost is not just "first pick" — additional SKUs and extra units also apply. At 3 different SKUs in an order, the T4 picking cost is: €0.40 (1st) + €0.20 (SKU 2) + €0.20 (SKU 3) = €0.80/order, not just €0.40. Our calculator reflects this reality with 3 picking sub-categories.
4. Ignoring storage per day vs per month
With us, storage is €0.40/m³ per DAY (= €12/m³/month for a standard 30-day month). The advantage: you pay proportionally for actual storage days. If goods arrive on the 25th of the month, you don't pay for a full month — you pay for just 6 days. This is very advantageous for stores with fast turnover. Calculators that only display "€/m³/month" hide a structural over-billing.
5. No per-order projection in the breakdown
Does a monthly total of €542 seem like a lot or a little? It depends on volume. At 500 orders/month, €542 = €1.08/order. At 5,000 orders/month, the same €542 = €0.11/order. Our calculator automatically displays both the cost per order and the breakdown by category (Pick&Pack, Storage, Receiving, Returns, Other) — exactly so you have the figure that matters for calculating your per-order margin.
How to read the result
What to do after completing the calculator
After completing all 3 columns, the calculator displays 3 totals (monthly + per order + annual) plus the detailed per-order breakdown. Here is how to correctly interpret the result:
- If "You (in-house)" is the lowest → either you have a very small volume (under 100 orders/month), or you haven't included all real costs in the in-house mini-calculator. Check that you have correctly entered: employee salaries (or the opportunity cost of your time if working alone), warehouse rent, utilities, WMS, realistic time per order (15–20 min without WMS, not 5 min), packaging materials at retail price.
- If "Competition" is the lowest → review the quote received carefully for hidden clauses. Request written confirmation that there is no: monthly minimum fee above a certain volume, Q4 peak surcharges, long-term storage fees after 30/60 days, address correction fees, restocking fees for returns, technology fees, courier margin. At operators with aggressive offers, one or more of these inevitably appear on the month-three invoice.
- If "Fast Fulfill" is the lowest → this matches our positioning: public prices, no hidden fees, no minimum, no setup, storage per day (not per month). Use the "See official calculator" button to verify any tier (T1-T8) with our more detailed official calculator and confirm prices are the same for all clients.
- Regardless of result → the annual difference is the figure that matters. A €100/month difference = €1,200/year. A €500/month difference = €6,000/year. These cumulative sums over 3–5 years of operation make the difference between a profitable store and one that barely survives. Over a 5-year horizon, a €1,500/month difference means €90,000 — a considerable marketing/development budget.

Frequently asked questions
FAQ on the fulfillment cost calculator
How is the real cost per order in an online store calculated?
The real cost per order in an online store is composed of 9 main categories: (1) Stock receiving at the warehouse (per unit); (2) Storage (per m³ per day or per month); (3) Picking the first SKU in an order; (4) Picking additional different SKUs; (5) Picking extra units of the same SKU; (6) Packing with materials (envelope, bubble envelope, small box, standard box); (7) Returns processing; (8) Additional services (barcode labelling, damage report, overweight); (9) Hidden fees (monthly minimum fee, setup fee). At Fast Fulfill, prices are public across 8 pricing tiers (T1-T8), and the minimum Pick & Pack cost is €0.42/order for Tier T8 with a product requiring no additional packaging.
How do Fast Fulfill prices change with order volume?
Fast Fulfill prices adjust automatically across 8 pricing tiers (T1-T8) based on monthly volume: T1 (0–30 orders) — receiving €0.31, pick €0.66, pack envelope €0.53; T2 (31–180) — €0.22 / €0.48 / €0.38; T3 (181–360) — €0.20 / €0.43 / €0.35; T4 (361–720) — €0.19 / €0.40 / €0.32; T5 (721–1,440) — €0.17 / €0.37 / €0.30; T6 (1,441–2,880) — €0.17 / €0.36 / €0.29; T7 (2,881–10,000) — €0.16 / €0.35 / €0.28; T8 (above 10,000) — €0.16 / €0.34 / €0.27. Storage is constant at €0.40/m³/day regardless of tier. For B2B clients, the tier is calculated based on total units dispatched (orders × units/order), not just the number of orders.
How is the in-house cost of an order in an online store correctly calculated?
The realistic in-house cost for an order is calculated with the formula: (operational time in minutes × hourly operating cost ÷ 60) + packaging materials at retail prices + proportional share of fixed costs (warehouse rent, utilities, WMS). Realistic hourly operating cost Romania 2026: €8–12/h (~40–60 RON/h) — calculated as gross picker salary + taxes + warehouse rent + utilities + amortised WMS ÷ hours effectively worked. Typical time per order for a solo entrepreneur without WMS: 15–20 minutes pick & pack. Envelope materials at retail price: ~€0.35/unit; small box: ~€0.80/unit; standard box: ~€1.50/unit. For a store with 500 orders/month, the realistic in-house cost reaches €3.50–4.50/order, vs €0.94–1.10/order at Fast Fulfill T4.
Why do simple fulfillment calculators give unrealistic costs?
Most simple calculators omit 4–5 critical cost categories that inevitably appear on the real invoice: monthly minimum fee (€200–500/month at some operators), initial setup fees (€500–2,000), Q4 peak season surcharges (+15–30%), long-term storage penalties after 30–60 days, address correction fees, overweight for products over 3 kg, hidden courier margin (5–15% over the real rate), and additional services billed separately (barcode labelling, damage reports). At Fast Fulfill, none of these fees exist in a hidden form — all prices are public on the website.
What is the mathematical difference between in-house cost, competition, and Fast Fulfill?
For a typical store with 500 orders/month, small product in a standard envelope, 5 m³ storage, 10% return rate: realistic in-house cost is typically in the €1,800–2,500/month range. Average competitor quote: €1,000–1,500/month (with included monthly minimum fees). Fast Fulfill Tier T4: €500–650/month, no minimum fee, no setup fee, storage at public €0.40/m³/day. Cumulative annual difference between the most expensive (in-house) and Fast Fulfill reaches €15,000–22,000/year for a 500 orders/month store.
How does the in-house mini-calculator for the "You" column work?
To correctly calculate your in-house cost, the mini-calculator asks questions you already know or can easily estimate: (a) workforce — how many employees you have and what gross salary/month you pay them, or (if working alone) what hourly opportunity cost your time has; (b) space — monthly warehouse rent, utilities, WMS; (c) time — how many minutes pick+pack, receiving, returns take; (d) materials — packaging cost per order at retail price. All values are pre-filled with realistic suggestions for Romania 2026 (picker salary ~€1,000 gross, rent 30 m² ~€240/month, entrepreneur hourly cost €20/h). The calculator automatically calculates the real hourly cost (salaries ÷ paid hours or your opportunity cost), then applies the formula minutes × hourly cost ÷ 60 + materials for each category.
