Smart Discounting Rules

Know when discounts hurt and when they boost lifetime value.

What this is for

Prevent margin erosion from blunt, habitual discounting while using targeted incentives to increase customer value and retention when it makes strategic sense.

Core logic

Discounts are a lever—not a default. The right discount accelerates acquisition, reactivation, or loyalty in a way that increases customer lifetime value net of the price cut. The wrong one simply conditions buyers to devalue your offer and shrinks margins. Apply discounts only when the incremental value (higher conversion, retention, upsell) outweighs the cost.

Step-by-step rules

1. Only discount when you can recover or multiply value

Use for:

First-time customer acquisition in high-LTV segments where the payback is clear.

Reactivation of lapsed customers with proven past value.

Volume or commitment upgrades (e.g., “buy 3, get 15% off” that increases AOV).

Avoid blanket discounts that don’t change behavior or just shift timing.

2. Tie discount size to economics

Cap the discount so acquisition payback still meets your LTV:CAC threshold (e.g., ensure the effective CAC after discount keeps LTV:CAC ≥ 3:1).

Never give a discount that pushes a deal below your real profit per sale unless it’s part of a calculated test with a recovery path.

3. Use conditional & structured incentives instead of straight price cuts

Time-limited upgrades (“lock in premium support for the first month”).

Bundled value (“add X for free when you commit today”) vs. price slashed.

Loyalty-based discounts (earned, not expected): “After 3 purchases, get 10% off next” builds habit.

4. Segment & qualify before discounting

Only offer to segments with high propensity to stick or expand.

Avoid discounting price-sensitive, low-LTV traffic that trains bargain behavior.

5. Control visibility

Use private or invitation-based discounts to avoid resetting general expectations.

Avoid sitewide “always” sales—frame as selective, earned, or event-based.

6. Test lift vs. erosion

Run small pilots: measure incremental conversion, retention, and downstream value from the discount.

Track how many customers would have bought without it (discount attribution) and how many become repeaters.

Decision thresholds / guardrails

Discount reduces payback below target → Don’t apply.

Customer won’t return or upgrade after discount → Abort that incentive style; it’s a one-off cost.

Discount becomes expected behavior in a segment → Retire or reframe (switch to value-added rewards).

High acquisition but low retention from discounted cohorts → Stop discounting that segment; fix onboarding or qualification instead.

Examples

SaaS: Offer a limited-time onboarding credit to new trial users in a high-LTV vertical; measure activation and upgrade rates to ensure the discount accelerates long-term value.

E-commerce: Instead of seasonal sitewide sales, give repeat customers an “earned” discount after two purchases, increasing loyalty without training bargain hunting.

Service: Provide a discount on the second engagement if the first resulted in a measurable outcome—encourages continuity while tying the discount to demonstrated value.

Thinking checks

Does the discount improve LTV or just push revenue forward?

Is the incentive targeted and conditional, or is it a blunt price chop?

Are you tracking discounted cohort behavior separately?

Have you capped exposure so you don’t erode perceived base price?
