Discounts are one of the easiest ways to create a quick increase in sales.
When traffic is expensive, conversions are slow, or inventory is not moving, a 10% or 20% discount can feel like the fastest solution.
And sometimes it works.
Orders increase. Conversion rate improves. Revenue rises for a few days.
But the immediate results can hide a more important question:
Did the discount actually improve profit?
A discount can increase the number of orders while still making the business less profitable.
Before reducing your price again, it is worth understanding what discounting changes, what it costs, and when price testing may produce a stronger result.
Why discounts feel so effective
Discounts create urgency.
They give customers a reason to make a decision now instead of later. They can also reduce price resistance and make a product feel more accessible.
For a Shopify brand, the visible impact may include:
- A higher conversion rate
- More completed checkouts
- Faster inventory movement
- Increased short-term revenue
- More attention during campaigns
These benefits are real.
The problem is that conversion rate and revenue do not tell the complete story.
A promotion may generate more orders while reducing the amount of profit earned from each visitor.
The hidden cost of a 20% discount
Imagine a product sells for $50.
The product costs $20 to produce and fulfill.
At full price:
| Metric | Value |
|---|---|
| Selling price | $50 |
| Product and fulfillment cost | $20 |
| Gross profit per order | $30 |
Now apply a 20% discount.
The selling price becomes $40:
| Metric | Value |
|---|---|
| Discounted price | $40 |
| Product and fulfillment cost | $20 |
| Gross profit per order | $20 |
The customer receives a 20% price reduction, but the business loses one-third of its gross profit per order.
The calculation changes from:
$50 - $20 = $30 profit
