Range and Odd-Number Anchoring combines two numerical signals. A range can make an offer feel flexible while steering attention toward an acceptable endpoint, but the counterpart will usually choose the end that benefits them. Therefore every number stated—especially the least favourable endpoint—must be a number you will honour. Do not expect the other side to volunteer the midpoint. Within or alongside that range, use a specific odd number supported by research or visible calculation. A figure such as 1,823 feels derived from facts, while a round number can look approximate and negotiable. The method is not permission to fabricate precision. Establish a real floor, support the figures with evidence, present the range, and remain consistent when the counterpart selects the endpoint you offered.
Origin
Voss shares examples of a student trapped by his own $18-$25 range and another who secured rent at $1,823 after visibly working through numbers.
Core principles
- 01The counterpart gravitates to the end of a range that favours them
- 02Every number in your range must be acceptable
- 03Specific odd numbers imply calculation rather than guesswork
- 04A visible calculation can strengthen perceived legitimacy
How to run it
- 1
Establish the true floor
Calculate the least favourable number you can accept without resentment or later retreat. Treat it as a real commitment.
Pro tip Include implementation costs, not just the headline amount.
Watch out Never put a bluff number at the attractive end of your range.
- 2
Construct the range
Choose a second endpoint that makes the range credible and supports your target. Assume the counterpart will immediately favour the endpoint best for them.
Watch out Do not rely on the counterpart choosing the midpoint.
- 3
Ground the anchor
Use research, costs, benchmarks, or another real calculation to support the number. Translate that work into a specific figure where appropriate.
Pro tip Visible calculation can reinforce that the number was derived rather than improvised.
Watch out Invented precision is deceptive and fragile under scrutiny.
- 4
Present and hold
State the researched range or specific number, then let the counterpart respond. If they select an endpoint you offered, honour it.
Watch out Rejecting your own endpoint marks the original range as false.
In the wild
A student wanted $21 an hour and said his research showed a range of $18 to $25, hoping the employer would choose the middle. The employer immediately offered $18. Because he had put that number forward as acceptable, rejecting it would have exposed the range as false.
→ The student learned that the counterpart will choose the endpoint favourable to them, not the hoped-for midpoint.
A Georgetown student visibly wrote figures on paper before offering $1,823 per month. The broker interpreted the specific odd number as the product of accounting and accepted it, even though the student had known his intended offer in advance.
→ Specificity and visible calculation made the anchor feel credible.
Common mistakes
Hoping for the midpoint
The counterpart is likely to choose the endpoint that benefits them, not split the stated range.
Offering a false floor
Refusing a number you volunteered damages trust and reveals that the range was not genuine.
Is it for you?
Best for
Price, compensation, rent, and other negotiations where the number itself shapes perceived credibility.
Not ideal for
Offers where no credible research or acceptable range can support the proposed figures.

“just make sure that you're happy with the short end of the stick”
“people will not drop the middle of that range you're hoping they will but they won't”
“odd numbers feel real they feel real to the other side”
