Estimate monthly contribution by subtracting expected variable service cost, payment fees and other incremental costs from the membership fee. Model utilization explicitly. Contribution is not net profit: fixed overhead, taxes, acquisition costs and future obligations need separate treatment.

## Write down the assumptions

Expected variable service cost equals redemptions per member per month multiplied by variable cost per redemption. Keep the time period consistent. If a benefit can be used twice in one month, do not cap the model at one redemption merely because billing is monthly.

## Test capacity and obligations

Model expected and full utilization, then check available appointment capacity. Stored-value balances are not the same as earned revenue. Have an accountant review revenue recognition, refunds and outstanding obligations before calling collections profit.

## Practical checklist

1. Record the monthly fee and benefit rules.
2. Estimate variable cost and utilization from your practice data.
3. Include payment fees and other incremental costs.
4. Compare expected and full utilization before launch.
5. Have the appropriate reviewer check terms and accounting.

## Worked example

An illustrative $149 fee less $36 service cost (0.8 redemptions at $45), $4.50 payment fees and $8 other costs leaves $100.50 contribution before fixed overhead. At 1.2 redemptions it falls to $82.50. These invented inputs demonstrate the arithmetic; they do not predict your margin.

## Mistakes to avoid

- Treating subscription cash as net profit.
- Ignoring unused-credit obligations or full utilization.
- Copying another practice’s price without checking cost and capacity.
