Core formulas
The formulas to keep straight
target sales = (fixed event cost + target profit) / profit per iteminventory to bring = target sales / expected sell-throughinventory value = units brought x selling priceprofit capacity = units brought x profit per item - fixed event costHow do you calculate craft fair inventory?
Calculate craft fair inventory by starting with target sales, then adjusting for sell-through. Target sales come from booth cost, target profit, and profit per item.
If the event needs 17 sales for target profit and you expect 70% sell-through, bring 25 units. That gives the table enough choice without assuming every unit sells.
The example inventory formulas were checked July 3, 2026.
Craft fair inventory formula, checked July 3, 2026
| Step | Formula | Example |
|---|---|---|
| Target sales | ($130 + $200) / $19.94 | 17 sales |
| Inventory at 70% sell-through | 17 / 70% | 25 units |
| Revenue capacity | 25 x $35 | $875 |
| Profit capacity if sold out | 25 x $19.94 - $130 | $368.50 |
What inventory mix should a craft fair table have?
A craft fair table should have enough profitable mid-price items to hit the sales goal, plus a small number of higher-priced pieces and add-ons. The mid-price items usually do the booth recovery work.
Do not let tiny add-ons dominate the table unless they attach to larger purchases. A $5 profit add-on needs 26 sales to recover a $130 event cost by itself.
Use the product mix to raise average order value, not to make the table look full.
Inventory mix example, checked July 3, 2026
| Product type | Units | Role |
|---|---|---|
| Mid-price repeatable item | 15 | Booth recovery |
| Premium item | 4 | Raises order value |
| Small add-on | 10 | Basket builder |
| Custom sample | 2 | Deposit or future order |
What happens if you bring too little inventory?
Too little inventory caps the event before the day starts. If the booth needs 17 sales for target profit and the seller brings 18 units, one uneven buying pattern can block the goal.
Too much inventory is not free either. It creates packing time, damage risk, display clutter, and cash tied up in unsold stock.
The practical answer is enough inventory for target profit at a realistic sell-through rate, then a backup plan for custom orders.
- Bring enough profitable units to beat the target-profit count.
- Avoid packing slow products just because there is space.
- Use signs or samples to capture custom orders after stock runs low.
- Review actual sell-through after the event.
Decision table
Craft fair inventory decision table, checked July 3, 2026
| Inventory issue | Best move | Reason |
|---|---|---|
| Too few units | Bring more repeatable stock | Target profit needs room |
| Too many slow items | Cut weak products | Clutter can reduce buying |
| Low average price | Bundle or add premium items | Booth recovery needs higher profit |
| Custom-heavy table | Use deposits | Future work should not be free |
| Fragile inventory | Limit stock and protect packaging | Damage can erase profit |
Worked examples
Examples you can compare against your own numbers
Example: inventory from target profit
A booth needs 17 sales for target profit. The seller expects 70% sell-through.
| Target sales | 17 | From break-even calculator |
|---|---|---|
| Expected sell-through | 70% | Local market estimate |
| Minimum units to bring | 25 | 17 / 70%, rounded up |
| Extra add-ons | 10 | Only if they lift basket size |
Takeaway: The sales target becomes useful only when it is converted into inventory.
Action checklist
Before you use this number in the real business
- 1Calculate target-profit unit count.
- 2Choose expected sell-through.
- 3Bring enough mid-price items to cover the target.
- 4Add premium items to raise average order value.
- 5Use add-ons only when they attach to larger sales.
- 6Track what sold, what did not, and what got damaged.

FAQs
Questions people ask before making the decision
How much inventory should I bring to a craft fair?
Bring enough inventory to cover your target-profit unit count after adjusting for sell-through. If you need 17 sales and expect 70% sell-through, bring at least 25 profitable units.
What is a good sell-through rate for a first craft fair?
Use a conservative estimate for a first event. A 50% to 70% planning range is safer than assuming the table will sell out.
Should I bring one of everything?
No. Bring enough of the products that can recover the booth. Samples are useful only when they lead to paid custom orders.
How do I plan inventory for different prices?
Use a blended average selling price. If the mix changes, rerun the break-even calculator with the new average.
Is selling out always good?
Selling out is good only if the profit target was met. Selling out low-profit items can still underpay the day.
What should I record after the event?
Record units brought, units sold, product mix, average order value, leftover stock, damaged stock, and net profit.
