SaaS marketing mix: designing the packaging together with retention.

SUPPORTED DECISIONChange an offer or a plan boundary only if the expected contribution per customer improves without artificially displacing the costs towards support or churn.

Key distinctions

Three conditions before calculating.

01

Self-selecting boundaries

Limits on seats, usage, automation or integration must separate needs that are expensive to serve. Removing a boundary can increase conversion while moving complex accounts to an under-priced plan.

02

Margin after service

Infrastructure, onboarding, customer success, support and annual discounts are attributed to the plan. Accounting gross margin can ignore the costs genuinely triggered by a service promise.

03

Retention by cohort

Average churn mixes maturity, segment and tenure. The calculation must use comparable cohorts and separate cancellation, contraction, expansion and plan migration.

Method

Assessing SaaS packaging from conversion to renewal

  1. 01Map the value

    Connect each feature or limit to a customer value mechanism, a supplier cost and a segment; boundaries with no economic justification are candidates for simplification.

  2. 02Reconstruct the net price

    Include annual discount, credits, free items, free months and average expansion; relate recurring revenue to the capacity genuinely consumed.

  3. 03Project the value

    Use the approximation LTV = monthly margin ÷ monthly churn only for relatively stable cohorts; also publish an observed survival scenario.

  4. 04Test the migrations

    Simulate acquisition, upgrade, downgrade and churn after a change; a forced migration is acceptable only if the contribution gain exceeds the plausible loss of retention.

ORIGINAL ASSET

Three plans compared by lifetime economics

Price, margin after service, churn and CAC are brought together so that a plan with high revenue is not automatically considered the best.

ILLUSTRATIVE EXAMPLE · SIMULATED DATA

The €149 plan creates a better ratio despite a doubled CAC

01 · SITUATION

The Team plan charges €89, keeps 75% margin after service, suffers 2.8% monthly churn and costs €900 to acquire. The Pro plan charges €149, keeps 70% margin, suffers 1.8% churn and costs €1,800 to acquire.

02 · CALCULATION

Simplified LTV for Team: 89 × 75% ÷ 2.8% = €2,384, that is 2.65 times the CAC. Pro: 149 × 70% ÷ 1.8% = €5,794, that is 3.22 times the CAC. Price alone would have hidden the retention effect.

03 · DECISION

The Pro plan can receive more acquisition, provided the observed churn is stable and onboarding does not cross a capacity step.

Acceptance conditions

What must be true to act.

  1. 01

    Every plan boundary corresponds to a documented value and cost.

  2. 02

    Margin includes variable infrastructure, onboarding, support and customer success.

  3. 03

    Retention is measured by plan, cohort, segment and tenure.

  4. 04

    Upgrade, downgrade and churn are simulated before any forced migration.

Limits

What this analysis does not prove.

  • The margin-divided-by-churn formula assumes a stability that is rarely perfect.
  • Annual contracts delay the observation of churn and can hide dissatisfaction.
  • Network and referral effects are not captured by a simple individual LTV.
