Conditional exact minor-unit ceil fixed-cost/contribution break-even with independently verified compatible programme cost/fee model. No demand forecast, member capacity or profitability guarantee.
Description
Membership break-even compares fixed program cost with per-member contribution.
Membership break-even compares fixed program cost with per-member contribution.1
A positive fee-minus-variable-cost contribution is required before a whole-member threshold exists.

How to use Membership Break-Even Member Count Calculator and understand its results
- Establish the object or visitor scope, measurement units and independently applicable conservation, engineering, access or editorial reference.
- Enter callerVerifiedFixedProgramCostMinor, callerVerifiedNetFeePerMemberMinor, callerVerifiedVariableCostPerMemberMinor, using the field meanings and rules below, then run the tool.
- Read result.conditionalWholeBreakEvenMemberCount. Use the units and sign conventions below.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| callerVerifiedFixedProgramCostMinor | Caller verified fixed program cost minor | number | Required |
| callerVerifiedNetFeePerMemberMinor | Caller verified net fee per member minor | number | Required |
| callerVerifiedVariableCostPerMemberMinor | Caller verified variable cost per member minor | number | Required |
Use nonnegative safe-integer fixed cost, net fee and variable per-member cost in one currency's minor units. Require fee−variableCost>0. Divide fixed cost by this contribution using BigInt and round up to whole members. Zero fixed cost returns zero.
wholeBreakEvenMembers=ceil(fixedCostMinor/(feeMinor−variableCostMinor)) Use the matching field units and the exact boundary, ordering and reference rules above.
