Walk-Away Price Calculator
Enter your cost floor, margin target, and deal variables to get a defensible walk-away number before the call, not a gut-feel figure invented live under pressure.
How to use it
Fill in the blank worksheet with your real cost and margin numbers before every negotiation, calculate your Deal Walk-Away Price using only the trades actually on the table, and never quote a number below your Absolute Floor without sign-off.
What's inside
- The 3 core inputs: cost floor, minimum margin, target margin
- The Absolute Floor and Target Price formulas
- Term, payment, and strategic-value flex allowances (capped)
- The single combined formula for your deal-specific walk-away price
- A fully worked numeric example end to end
- A blank fill-in-your-numbers worksheet version
- The rule for when a number requires executive sign-off
The formula and logic behind a defensible walk-away number
Step 1, Your inputs
- Cost Floor (C), fully-loaded annual cost to deliver: COGS + implementation cost + ongoing service cost.
- Minimum Acceptable Margin (M_min), the margin below which this deal loses money in any way that matters. Typically set by finance.
- Target Margin (M_target), the margin you're actually aiming to hold.
Step 2: The two anchor prices
Absolute Floor = C ÷ (1 − M_min) Never go below this without executive sign-off, regardless of any trade offered.
Target Price = C ÷ (1 − M_target) Your anchor, what you're aiming to hold through the negotiation.
Opening Price = Target Price × 1.15 (or your standard list markup) Gives room to "concede" down to Target during negotiation without ever threatening the floor.
Step 3, Flex allowances (only apply if genuinely traded for)
| Trade offered by buyer | Flex allowed |
|---|---|
| Contract term ≥ 24 months | up to 5% |
| Annual upfront payment (vs. monthly) | up to 3% |
| Named logo / case study rights | up to 5% |
| Reference calls | up to 3% |
| Documented high expansion potential | up to 5% |
| Total flex budget | capped at 10%, regardless of how many boxes are ticked |
Month-to-month terms move the OTHER direction: add a 10% premium to Target Price to compensate for higher churn risk, this is not a discount scenario.
Step 4: The combined formula
Deal Walk-Away Price = MAX( Absolute Floor, Target Price × (1 − Flex Budget) )
This one line does the job: it lets genuine trades pull your number down toward, but never below, your true floor.
Worked example
- Fully-loaded cost to deliver: C = $40,000/year
- Minimum acceptable margin: M_min = 40% → Absolute Floor = 40,000 ÷ (1 − 0.40) = $66,667
- Target margin: M_target = 60% → Target Price = 40,000 ÷ (1 − 0.60) = $100,000
- Opening Price = 100,000 × 1.15 = $115,000
Buyer offers: 24-month term (+5% flex) + annual upfront payment (+3% flex) + one case study (+3% flex) = 11%, capped at 10%.
Deal Walk-Away Price = MAX( $66,667, $100,000 × (1 − 0.10) ) = MAX( $66,667, $90,000 ) = $90,000
Reading it: open at $115,000, hold at $100,000 as long as possible, and do not go below $90,000 for these specific trades. If the buyer wants to go lower than $90,000, you need an additional trade: or executive approval, since you're now moving toward the true $66,667 floor.
Blank worksheet, fill in your own numbers
| Field | Your number |
|---|---|
| Cost Floor (C) | $ |
| Minimum Acceptable Margin (M_min) | % |
| Absolute Floor = C ÷ (1 − M_min) | $ |
| Target Margin (M_target) | % |
| Target Price = C ÷ (1 − M_target) | $ |
| Opening Price = Target × 1.15 | $ |
| Flex from term offered | % |
| Flex from payment terms offered | % |
| Flex from strategic value offered | % |
| Total flex (cap at 10%) | % |
| Deal Walk-Away Price = MAX(Floor, Target × (1 − Flex)) | $ |
Rule: any number below your Absolute Floor requires named executive sign-off before you say it out loud on a call, no exceptions for urgency or quota pressure.
