How to define a price floor to avoid selling at a loss while staying competitive

• Define the minimum profitable price for each product
• Include costs, commissions, shipping and margin targets
• Monitor competitor prices before adjusting your own
• Use price floors in repricing rules to protect profitability
• Stay competitive without selling below cost

Why a price floor is essential in ecommerce pricing

A price floor is the lowest price at which a product can be sold without damaging profitability. It protects ecommerce businesses from lowering prices too far when competitors become more aggressive.

Without a clear price floor, teams risk:

• Selling products at a loss
• Matching competitors with unsustainable pricing
• Damaging margins on strategic products
• Entering price wars
• Automating repricing without profitability safeguards

A strong pricing strategy should always define how low prices can go before any manual or automated adjustment is applied.

How to define a price floor

1. Calculate the full cost of each product

The first step is to understand the true cost of selling each product. The price floor should not be based only on purchase cost.

It should include:

• Product purchase cost
• Marketplace commissions
• Payment fees
• Shipping and fulfilment costs
• Return costs
• Advertising or acquisition costs
• Operational costs

The more complete the cost calculation, the safer your pricing rules will be.

2. Add a minimum margin target

Once the full cost is calculated, define the minimum margin you want to preserve. This margin can vary depending on the product, category, channel or market.

For example:

• High-volume products may accept a lower margin
• Premium products may require a higher margin
• Marketplace products may need to include commissions
• Advertising-driven products may need to account for acquisition costs
• Seasonal products may use temporary margin thresholds

This minimum margin becomes the foundation of your price floor.

3. Compare your price floor with competitor prices

Once your price floor is defined, compare it with competitor prices. This helps determine whether you can remain competitive while staying profitable.

With NetRivals, ecommerce teams can monitor competitor prices across DTC websites, marketplaces and comparison shopping engines.

This enables teams to understand:

• Which competitors are below your price floor
• Which competitor prices can be matched profitably
• Where you should maintain your price instead of following the market
• Which categories are exposed to margin pressure
• Where competitors may be applying temporary or unsustainable discounts

How to use a price floor in repricing rules

A price floor becomes especially powerful when connected to automatic repricing.

Useful repricing rules include:

• Never price below the defined price floor
• Match the lowest in-stock competitor only if the price remains above the floor
• Ignore competitors below the floor when their prices are not profitable for your business
• Stay within a defined price gap from the market average
• Increase prices when competitors raise their prices or go out of stock
• Apply different floors by category, channel, country or product segment

These rules help teams stay competitive without losing control over margins.

Example: defining a price floor for a strategic product

Imagine a retailer selling a product with the following cost structure:

• Purchase cost: €60
• Marketplace commission: €8
• Shipping and fulfilment: €6
• Advertising cost allocation: €4
• Minimum margin target: €12

The minimum profitable selling price is therefore €90.

If a competitor sells the same product for €85, the retailer should not automatically match that price. Instead, the retailer can:

• Maintain the price at or above €90
• Check whether the competitor is in stock
• Monitor whether the competitor discount is temporary
• Adjust only on specific channels if needed
• Use a repricing rule that blocks any price below €90

This protects profitability while keeping pricing decisions controlled.

Best practices for setting price floors

To make price floors effective, they should be reviewed regularly and adapted to business conditions.

Best practices include:

• Calculate price floors at product or category level
• Include all variable costs, not only purchase costs
• Use different price floors by channel when fees vary
• Exclude out-of-stock competitors from repricing decisions
• Monitor competitors below your floor without automatically following them
• Review thresholds during promotions, peak seasons or cost changes
• Combine price floors with historical price and performance data

This allows teams to remain competitive without putting profitability at risk.
