You need to raise a product's price when the real margin falls below your break-even point, when input costs rise more than 10%, when demand consistently outpaces stock, when you're offering installments without absorbing the financing cost, or when competitors have already raised their prices and you haven't. You don't need to guess the moment: the margin per SKU tells you.
Why do most sellers wait too long to raise prices?
Fear. Raising a price is visible, immediate and has a face — customers see it. Shrinking your margin is invisible: customers don't know you're selling at a loss, and often neither does the owner. That asymmetry leads most sellers to wait until the problem has no easy fix: they either raise prices all at once and lose customers, or keep selling cheap until the cash register stops balancing.
The solution isn't courage — it's data. When you have real margin per product updated in real time, the decision of when to raise prices stops being a bet and becomes a dashboard reading. What you need is to know when margin dropped to an unsustainable level, not to calculate when it "feels" right to raise it.
The 5 signals that tell you it's time to raise the price
Signal 1: your real margin fell below the break-even point
The break-even point is the minimum price at which you can sell without losing money, counting all costs: product, shipping, platform fees, payment gateway and advertising. If your current price is below that number — or has gotten close enough that any discount crosses it — you're not in a decision zone. You're in an emergency zone. See how to calculate it in our e-commerce break-even point guide.
Signal 2: your input costs rose more than 10%
If your production or purchasing cost rose more than 10%, the sale price has to move in the same direction — or margin compresses to the point of being unsustainable. In markets where costs move with exchange rates and inflation, that adjustment should be automatic, not a one-off decision that keeps getting postponed.
Signal 3: demand consistently outpaces stock
If your product sells out before the next batch arrives and you have customers waiting or buying from a competitor, the price is too low for the demand that exists. In that context, raising the price doesn't reduce sales — it gives you margin to finance more stock and serve the demand that's already there.
Signal 4: you're offering interest-free installments without absorbing the financing cost
Interest-free installments have a real cost the seller absorbs. With Mercado Pago in Argentina, 3-installment financing costs an additional 10.49% of the sale price (plus VAT). If your list price doesn't include that cost, every installment sale silently eats your margin. The fix is to raise the list price or charge a differential for installments. More detail in our Mercado Pago interest-free installments cost guide.
Signal 5: competitors have already raised their prices and you haven't
If other players in the market have adjusted their prices and you've held yours, you have two effects running simultaneously: you look cheaper (useful for a short time) and you're compressing your margin relative to the market. When the market stabilizes at the new price, your old price is a competitive disadvantage disguised as an opportunity.
How much to raise it? The target margin table
The answer depends on your category's target margin. An example using a product with a total cost of ARS 50,000 (product + shipping + fees, excluding advertising):
| Target margin | Minimum price (no installments) | With 3-installment plan (+10.49%) |
|---|---|---|
| 15% | ARS 58,824 | ARS 65,192 |
| 20% | ARS 62,500 | ARS 69,256 |
| 25% | ARS 66,667 | ARS 73,870 |
| 30% | ARS 71,429 | ARS 79,117 |
Minimum price = cost ÷ (1 − target margin). Installment cost is added on top of that result. For the full calculation method with all costs included, see our how to calculate selling price guide.
The most common mistake when raising prices: updating the sale price without updating the product cost in your analytics system. If Escalafy doesn't receive the new cost, the calculated margin still reflects the old price. The number looks better but the model is wrong from the ground up.
What happens if the price goes up and sales go down?
It's the question that paralyzes most sellers. The short answer: it depends on the product and its price elasticity. In niche categories — specialized products, brands with a strong identity, consumables with repeat buyers — the volume drop after a price increase is much smaller than it seems. What matters isn't how many units you sold, it's how much you earned in total.
If you sell 100 units at ARS 5,000 with a 10% margin, you earn ARS 50,000. If you raise to ARS 6,000 and sell 90 units with a 20% margin, you earn ARS 108,000. You sold less and earned more than twice as much. That calculation only works if you have margin per SKU updated in real time. See how it works in Profit by Product in Escalafy.
How to know, with real data, whether a price increase improved your business
Raising a price is a hypothesis. To confirm it worked you need to compare at least 30 days before and 30 days after, under similar advertising conditions. The numbers to check: total profit for that product in the period, profit per unit sold, sales volume and the Real ROAS of campaigns promoting it. If the first three improved even though the fourth dropped slightly, the increase was correct.
Escalafy gives you that comparison without building a report manually: you can see the margin for any SKU by period and whether the price adjustment improved or hurt overall profitability. Also read our e-commerce contribution margin guide to understand which number to use as your reference.
Frequently asked questions
How much notice do I need to give before raising prices?
There's no legal obligation to announce it in e-commerce, except in regulated categories. The most common approach is to update the price directly. It's only worth communicating it if you have a base of frequent buyers who might want to use the previous price on one last purchase.
Can I raise the price on only some variants of the same product?
Yes. If you have variants with different costs (extra size, premium material, bundle), you can update each price separately. Escalafy calculates margin at the variant or SKU level, so you can see exactly which one needs adjustment without touching the others.
How do automatic discounts affect a price increase?
A 10% discount applied to a price you raised by 8% leaves you at the original price but with a higher commission cost. Before raising prices, check what automatic discounts are active and what the net effect actually is. The discounts and profit margin in e-commerce guide has the detailed math.
