What does the repricing floor calculator compute?

Three numbers in one keystroke: a margin-safe floor (cost / (1 - targetMargin%/100)) that guarantees every cleared sale earns your target margin over COGS, a competitor-aware target (competitor median minus your chosen undercut delta), and a recommended replicated price that picks the cents-rounded maximum of the three so you never undercut yourself or your margin by accident.

When should I use the repricing floor calculator instead of the Amazon FBA profit calculator?

Use the FBA profit calculator when the selling price is fixed and you want to see the profit / margin / ROI that comes out the other side. Use the repricing floor calculator when selling price is the unknown and you want the price that protects your margin while staying under the competitor median.

When should I use the repricing floor calculator instead of the breakeven price calculator?

The breakeven calculator absorbs monthly overhead (rent, salaries, tools) into the markup headroom at a per-unit level. The repricing floor calc lives entirely on a per-unit competitor field: it returns the margin-safe floor over COGS plus a competitor-aware target, with no monthly overhead absorbed. Use breakeven for a month-spanning baseline, repricing for a single-SKU field decision.

How do I pick the undercut delta per unit?

The default is $0.05 — a small, repeatable buy-box nudge that keeps you under the competitor median without burning margin. Raise it (e.g. $0.25 - $1.00) when the competitor median moves frequently and you want to win the buy box more aggressively; lower it (e.g. $0.01) when you want to protect margin and treat the median as informational only.

Is the repricing floor calculator free?

Yes. The calculator is free, requires no signup, and runs entirely in your browser.
