Pricing strategy calculator.
Keystone, 3x, or work backwards from the margin you need? This prices the same product five ways and shows what each one actually leaves you after fees and ad spend — then recommends one.
Your costs
Candidate prices
| Strategy | Retail | Net / unit | Net margin |
|---|---|---|---|
| Target margin (25%) Pick | $18.99 | $5.14 | 27.1% |
| Keystone (2x landed cost) | $19.99 | $5.91 | 29.6% |
| 2.5x landed cost | $23.99 | $9.00 | 37.5% |
| 3x landed cost | $28.99 | $12.85 | 44.3% |
| 4x landed cost | $38.99 | $20.56 | 52.7% |
Price it at $18.99
It is the lowest of these that still clears your 25% target (27.1% net, $5.14 a unit). A lower price converts better, so there is no reason to reach past it.

How this is calculated
- Landed cost
- product cost + shipping
- Net profit at any price
- price × (1 − platform fee % − ad spend %) − landed cost
- Fees and ad spend are both taken as a share of revenue, so they scale with the price. Landed cost does not — which is why raising the price lifts margin faster than it lifts profit.
- Breakeven price
- landed cost ÷ (1 − platform fee % − ad spend %)
- Target-margin price
- landed cost ÷ (1 − platform fee % − ad spend % − target margin %)
- Solved directly from the net-profit formula rather than marked up and checked afterwards.
- Charm pricing
- round up to the next X.99
- Always rounds up, never down, so the charm price never quietly cuts your margin below the strategy it is named after.
Multiples of cost (keystone, 3x) are habits, not laws — they ignore fees and ads entirely. They are here so you can see what they really leave you next to a price derived from the margin you asked for.
