Interpreting Results

Input Steps
Field by field
- 1
Mode
Pick the correct mode first: margin to price, markup to price, discount to sale price, or sale price to discount. Then enter cost, list price, sale price, and the relevant percentage so the math reflects if you are setting a new price, evaluating a markdown, or reverse-checking a quote.
- 2
Cost
Read sale price, gross profit, margin percent, markup percent, discount percent, and the formula trace. Use it to catch common interpretation errors, such as assuming 50% markup equals 50% margin when it actually equals a 33.3% margin.
- 3
Margin Percent
Treat warnings as decision signals, not cosmetic notes. Margin above 80% often means cost input is incomplete, a discount above 60% usually indicates clearance pricing, and any sale price below cost means the transaction destroys gross profit immediately.
- 4
Setup
Use the output to set standard pricing guardrails for sales teams, promo calendars, and quote templates. If a planned discount drops margin below your minimum acceptable threshold, change bundle structure or add value before approving the offer.
- 5
Setup
Re-run for every supplier cost change, promo test, or channel-specific price list. Track average realized discount and post-discount margin by channel because discount creep often grows slowly enough to hide until gross profit compresses.
Run one base case and one sensitivity case before trusting a single output.
