A quick, Monday-morning way to choose between pricing models. Construct two or three pricing options that are mathematically identical in total cost — plus an explicit 'I'm indifferent' choice — and ask customers to pick. Rational economics says everyone picks indifferent. Across thousands of tests, indifferent never wins. Whichever structure people gravitate to reveals the model your market actually wants.
Origin
Madhavan Ramanujam's field test at Simon-Kucher, offered on Lenny's Podcast as the cheap alternative to a full pricing-model study. It is an applied instance of behavioral pricing — the same rejection of the purely rational buyer that underlies Dan Ariely's Predictably Irrational.
Core principles
- 01Construct the options so they break even — the math must be identical across choices.
- 02Always include an explicit 'indifferent' option; it is the control.
- 03The indifferent option never wins, and that is the finding: preference over structure is real and irrational.
- 04You are testing structure preference (fixed vs variable weighting), not price level.
How to run it
- 1
Fix the total economics
Pick a representative customer scenario and a total price you would charge them. Every option in the test must sum to that same total.
Watch out If the options are not genuinely break-even, you are testing price level and the result is worthless.
- 2
Build 2-3 structurally different but economically identical options
Marketplace example on a $100 item: 3% transaction fee, or 1.5% transaction fee plus $1.50 flat, or $3 flat — plus 'I'm indifferent'. B2B SaaS at 100 seats: $1,000 platform plus $10/seat, or $2,000 flat, or $500 platform plus $15/seat.

Ask customers to choose and read the pattern
Watch which structure wins. 'I like the lower platform fee and the variable' versus 'I like the fixed' is the signal telling you whether your market wants a subscription-weighted, usage-weighted, or hybrid model.
Pro tip Because the total is identical, you can adopt the winning structure at zero economic cost and gain a preference win for free.
In the wild
On a $100 item, sellers are offered a 3% transaction fee, a 1.5% fee plus $1.50, a flat $3, or 'indifferent'. All four cost exactly $3.
→ Ramanujam has run this thousands of times and has never seen 'indifferent' win — people always pick a structure, revealing which monetization model the market prefers at zero economic cost.
A 100-seat customer is offered $1,000 platform + $10/seat, $2,000 flat, or $500 platform + $15/seat. All three total $2,000.
→ Buyers reliably split into 'lower platform fee, more variable' versus 'give me the fixed price' camps — which is exactly the input needed to choose between seat-based, flat-contract and hybrid models.
Common mistakes
Assuming rational buyers will be indifferent
Business-school economics predicts indifference when the math is identical. In thousands of real tests it never happens — meaning your model choice has real revenue consequences even at constant economics.
Testing structures at different total prices
If the options don't break even, respondents just pick the cheapest and you learn nothing about structural preference.
Is it for you?

Not ideal for
Deciding price level or elasticity — that requires threshold or trade-off methods, not this test.
From the transcript
“the easy Monday morning thing that I can actually ask your listeners to do is what we call as a break-even exercises”
“I've done this thousands of times I've never seen the you know indifferent actually win it's always people who pick one or the other”
