When to use percentage vs flat discounts
The Problem
"10% off" is meaningless for ₹500 purchase (₹50 discount), feels cheap for ₹5,000 purchase (₹500 discount). Wrong discount type kills perceived value or margin.
When you offer "10% off" to all customers, you're actually offering wildly different things. For someone buying a ₹800 skincare product, 10% = ₹80. That might feel okay, but not exciting. For someone buying a ₹5,000 dress, 10% = ₹500. That feels substantial—maybe too substantial for your margin.
The opposite problem happens with flat discounts. "₹200 off" sounds great on a ₹1,000 purchase (20% off!), but insulting on a ₹10,000 purchase (2% off). Your luxury customers feel undervalued while your budget customers get over-discounted.
Most merchants pick one type and use it everywhere. This leaves money on the table: either you're over-discounting low AOV orders (killing margin) or under-discounting high AOV orders (missing conversions).
When This Applies
Recommended For
- •Setting up any discount campaign
- •Unsure which discount type to use
- •Want to maximize perceived value while protecting margin
- •Have customers across different price points
Not Recommended For
- •Single-price-point products (everyone buys at ₹999, doesn't matter)
- •No margin pressure (both types work fine)
Recommended Approach
The Decision Matrix
The Psychology Behind Each Type
Flat Discounts (₹200, ₹300, ₹500):
- Advantage: Concrete and immediate ("I'm saving ₹300!")
- Perception: Feels like "found money"
- Best for: Lower AOV, first-time purchases, clear value prop
- Math: Customer doesn't calculate percentage, just sees ₹ saved
Percentage Discounts (10%, 15%, 20%):
- Advantage: Scales with purchase size ("The more I buy, the more I save")
- Perception: Rewards bigger baskets
- Best for: Higher AOV, sales events, luxury positioning
- Math: Customer does math, feels smart about "deal"

The AOV-Specific Examples
Low AOV (₹500-₹1,000):
Medium AOV (₹1,500-₹3,000):
High AOV (₹8,000+):
| Your AOV Range | Use This Discount Type | Why |
|---|---|---|
| <₹1,000 | Flat (₹50-₹150) | Percentages feel too small (10% of ₹500 = ₹50) |
| ₹1,000-₹3,000 | Flat (₹200-₹500) | Easier math, feels more concrete |
| ₹3,000-₹8,000 | Either (test both) | Depends on category positioning |
| ₹8,000+ | Percentage (5-10%) | Flat amounts feel cheap for luxury |
Step-by-Step Setup
Calculate your current average order value (AOV)
›Last 30 days: Total revenue ÷ Number of orders
›Example: ₹6,00,000 ÷ 400 orders = ₹1,500 AOV
Use the decision matrix
›₹1,500 AOV → Flat discounts (₹200-₹500 range)
If you have wide AOV variance, consider segmentation
›Check: What's your AOV range? (₹500-₹5,000 is very wide)
›If wide: Use different discount types for different campaigns
›Example: Flat for acquisitions, percentage for retention
Set discount amount based on margin
›Calculate: Gross margin - desired profit = max discount budget
›Example: 50% margin - 20% profit goal = 30% max discount
›If flat: ₹1,500 AOV × 20% = ₹300 flat discount
›If percentage: 20% off maximum
A/B test if unsure
›Split traffic 50/50
›Group A: Flat discount (₹300 off)
›Group B: Percentage discount (20% off, same ₹300 value at AOV)
›Run for 2 weeks minimum
Measure key metrics
›Conversion rate (flat vs percentage)
›AOV (does percentage encourage bigger baskets?)
›Margin impact (same discount $ but different perception)
›Customer feedback (which feels more valuable?)
Choose winner and implement
›Winner = Higher conversion rate + same or better AOV
›If percentage wins AND increases AOV → clear winner
›If flat wins but AOV stays same → also good (simpler)
Document for future campaigns
›Record: "Flat ₹300 converts 5% better than 20% off"
›Use this learning for next campaign
›Re-test annually (customer behavior changes)

Common Mistakes to Avoid
Using low percentages on low AOV
Feels insignificant, doesn't motivate purchase
Fix: Use ₹100 flat discount (same cost, better perception)
Using flat discounts on luxury/high-ticket
Feels insulting, not premium
Fix: Use 10% off (₹2,000 saved, feels generous)
Not testing both types
Customer perception varies by category
Fix: A/B test for 2 weeks, measure conversion + AOV
Mixing types in same campaign
Confusing, customer questions if discount is correct
Fix: Pick one format, use consistently across all touchpoints
No minimum on percentage discounts
₹100 order gets ₹20 off (you pay processing fees for ₹80 sale)
Fix: "20% off ₹1,000+" to ensure minimum viable order
Flat discounts that are too complex
Odd number feels calculated, not generous
Fix: Round to ₹300 (feels like a gift, not a calculation)
Percentage discounts that require mental math
Has to calculate what that means for their ₹1,234 cart
Fix: Use round numbers (15%, 20%, 25%)
