What the file tells you

A 30% discount needs 76% more units just to break even — on a good-margin product. Most promos never get there. This sheet finds the break-even for every product, judges every planned promo before it goes live, and keeps score afterwards, so Black Friday makes money on purpose.

01 · verdictSafety — promos below the margin floor or needing impossible uplift
02 · verdictGiveaway — discount handed back this season, the biggest one, products with no room
03 · verdictTrack record — ended promos won or lost against doing nothing, your real uplift
Sheets in the workbook
✓Planner · the ritual page
✓Products · max safe discount and break-even uplift at 10, 20, 30% off
✓Promos · one line per promotion — SAFE / RISKY / UNREALISTIC / LOSS before it goes live
✓Results · what it actually sold — WON or LOST
How it works
1Set fees, the margin floor and the largest uplift you believe in — ten minutes, once
2Type the promo before it goes live — SKU, discount, dates, baseline, expected uplift — the verdict appears
3Type results when it ends — the next plan is calibrated on real uplift, not hope
Who it is for

Store owners planning seasonal sales, coupons and clear-outs — anyone who has ever had a record-revenue week and a worse bank balance.
