Calculate the break-even conversion lift you need and discover when free shipping is a better strategy than percentage discounts. **TL;DR:** A 20% discount on a product with 60% margins requires a 50% increase in orders just to break even on profit. Free shipping thresholds set 20-30% above your AOV often outperform percentage discounts because they increase order size instead of reducing price. ## Enter Your Product & Discount Details Product Price ($) The selling price before any discount Please enter a valid price greater than 0.

Analyze Discount Impact ### Discount Impact Analysis Without Discount (Current) Revenue per Order -- Profit per Order -- Margin -- Monthly Revenue -- Monthly Profit -- With Discount Applied Discounted Price -- Profit per Order -- New Margin -- Margin Reduction -- Projected Monthly Orders -- Monthly Revenue (with discount) -- Monthly Profit (with discount) -- Break-Even Analysis Break-Even Conversion Lift Needed -- Profit Difference (Monthly) -- 1. 1**Use free shipping thresholds instead** — Set the threshold 20-30% above AOV to increase order size without cutting price. 2. 2**Offer free gifts over discounts** — A low-cost gift feels more valuable than a small percentage discount. 3. 3**Limit discounts to new customers only** — Use a spin wheel popup to capture emails and offer a one-time discount. 4. 4**Use volume discounts** — "Buy 2 get 10% off" increases total order value even with the discount. 5. 5**Set discount expiry dates** — A countdown timer creates urgency and prevents discount code hoarding. ## The Hidden Cost of Discounting Discounts feel like an easy lever to pull when sales are slow. Offer 20% off, watch orders increase, and celebrate the revenue bump. But most merchants do not calculate the true profit impact of their discounts, and the results are often surprising. Here is the core problem: **discounts reduce your margin per unit far more than the discount percentage suggests**. If you sell a $50 product with $20 in cost of goods (a 60% gross margin of $30), a 20% discount drops your price to $40. Your COGS stays at $20, so your new margin is $20 per unit. That is a 33% reduction in profit per sale from a 20% discount. To maintain the same total profit, you now need to sell 50% more units. This is not intuitive, which is why so many stores run unprofitable promotions without realizing it. The calculator above makes this math transparent so you can make informed decisions about when and how much to discount. ## Break-Even Conversion Lift: The Number You Must Know Before offering any discount, calculate your break-even conversion lift. This is the minimum percentage increase in orders you need to maintain the same total profit: **Break-Even Conversion Lift = (Original Profit / Discounted Profit) - 1** If your estimated conversion lift is lower than the break-even threshold, the discount will lose you money even though revenue may increase. Revenue going up while profit goes down is a common trap that catches many Shopify merchants. ## When Free Shipping Beats Percentage Discounts Free shipping thresholds are almost always a better strategy than percentage discounts for one critical reason: they increase order value instead of decreasing it. When you set a free shipping threshold at $75 (20-30% above a $60 AOV), customers add more items to reach the threshold. Your revenue per order goes up, not down. The cost of offering free shipping is typically $5-$8 per order. Compare that to a 15% discount on a $60 order, which costs you $9 per order and actually reduces the order value. A [free shipping bar](https://easyappsecom.com/apps/free-shipping-bar.html) visually shows customers how close they are to the threshold, which drives an average **AOV increase of 15-25%**. The only scenario where percentage discounts clearly outperform free shipping is for high-value items where the shipping cost is negligible relative to the product price (e.g., a $500 product where $7 shipping is irrelevant to the customer). ## The Optimal Discount Percentage If you decide that a discount is the right strategy, the percentage matters enormously. Research across thousands of Shopify stores shows these patterns: **5% off:** Rarely changes behavior. Not worth the margin erosion. ## Avoiding Discount Fatigue Discount fatigue is a real and measurable phenomenon. Stores that discount too frequently see declining conversion rates on non-sale days, customers abandoning carts to wait for codes, and increasing email unsubscribes except during promotions. The long-term revenue impact of discount fatigue almost always exceeds the short-term revenue gains from the promotions that caused it. To avoid discount fatigue, limit major promotions to 2-3 times per year, use alternative incentives like free gifts or bonus loyalty points, and reserve discount codes for specific segments (new customers, VIP loyalty tier) rather than site-wide sales.
