Here's the comprehensive formula that accounts for all costs:
Break-Even Formula
Step 1: Calculate Your Variable Costs Per Unit

|---|---|---|
| Product Cost (COGS) | Unit cost from supplier including shipping to you | $3.00 - $25.00 |
| FBA Fulfillment Fee | Amazon's pick, pack, ship fee (size-tier based) | $3.00 - $15.00 |
| Referral Fee | Amazon's commission (typically 15% of selling price) | 15% of price |
| Storage Fee (per unit/month) | Monthly storage cost divided by expected monthly sales | $0.10 - $0.75 |
| Inbound Shipping | Cost to ship from supplier to Amazon warehouse | $0.50 - $3.00 |
| PPC Cost per Sale | Average ad spend to generate one sale | $2.00 - $12.00 |
Step 2: Calculate Your Fixed Costs
Fixed costs remain constant regardless of sales volume:
- Product photography: $300-$1,500 (one-time)
- Initial inventory order: Include any minimum order costs
- Product samples & testing: $100-$500
