# **FBA Valuation Calculator**

What your business would sell for — SDE, multiple, and deal value

**1 ****The money — last 12 months**

**Net profit, last 12 months **

Before paying yourself — the number sellerboard or your P&L shows

**Add-backs (optional) **

Your salary + one-time costs a buyer won't inherit

**Total sales, last 12 months (optional) **

Only used to sanity-check your numbers

**Sellable inventory at landed cost (optional) **

What you paid to make and ship it — not retail value

**2 ****The business**

**How long have you been selling this brand? **

**Sales vs the previous 12 months? **

**Your best seller's share of revenue? **

**Hours you work on it per week? **

**3 ****Risk & transferability**

**Registered trademark + Brand Registry? **

**Revenue outside Amazon? **

**Backup supplier if yours disappeared? **

**Suspension or serious policy strike, last 2 years? **

## **How the valuation works — the same math buyers use**- **SDE: the number buyers pay for** Seller's discretionary earnings is your last-12-months net profit plus everything you personally take out — your salary, perks, and one-time costs a new owner won't inherit. Businesses under about $1M in earnings are priced as a multiple of SDE, so every documented add-back dollar is worth its amount times your multiple. - **What sets your multiple** Size sets the base — bigger earnings command higher multiples — then growth trend, product spread, trademark protection, your weekly hours, off-Amazon revenue, supplier backup, and account health each move it by a documented amount. The calculator shows every one of those moves, nothing hidden. - **Inventory is paid separately** The multiple applies to SDE only. Buyers purchase your sellable inventory on top, at landed cost — what you paid to make and ship it — and may exclude stale stock. Bloated inventory doesn't raise your price; it scares buyers about working capital. - **"32×" and "2.7×" are the same number** Marketplaces like Empire Flippers quote a multiple of average monthly net profit (20–60×); brokers and M&A advisors quote annual SDE multiples (2–5×). Divide a monthly quote by 12 before comparing offers — mixing the two misvalues a business by an order of magnitude. - **Preparation pays, literally** Sellers who start preparing one to two years before listing exit at roughly 2.7× the price of sellers who want out immediately: clean separate books, accrual accounting, a filed trademark, documented SOPs, and fewer owner-hours all show up directly in the multiple. - **Why you get a range, not a number** The estimate is calibrated to what businesses actually sold for in 2024–2025, not asking prices, which run 15–18% higher and usually don't clear. The final price is set by due diligence, buyer competition, and deal structure — so an honest tool gives you a range. ## **Selling an Amazon FBA business**
