What Happens If You Raise Your Prices?

Understand Price Increases, Sales Volume Changes, and Their Impact on Profit

You Need to Raise Your Prices. But What If Customers Buy Less?

Your suppliers have increased their prices. Packaging and delivery costs are rising. Your profit margins are getting tighter.

Raising your selling prices seems like a reasonable solution.

But there's a concern.

What if your customers respond by buying less?

A price increase can improve the contribution earned from each sale. However, if sales volume falls too much, your business could end up generating less total contribution than before.

The question isn't simply whether you should increase your prices.

It's how much sales volume you can afford to lose before the price increase stops making financial sense.

1. Why a Higher Price Doesn't Always Mean Higher Profit

When you increase your selling price, your contribution per unit generally improves if variable costs remain unchanged.

But your total contribution depends on two things:

A higher contribution per unit can offset some reduction in sales volume.

However, if customer demand falls beyond a certain point, the price increase may reduce your overall contribution.

That's why pricing decisions should consider both margins and possible changes in customer behavior.

2. Understand Your Contribution Before Changing Prices

Contribution per unit is the amount remaining after variable cost per unit is deducted from the selling price.

Contribution per Unit = Selling Price − Variable Cost per Unit

Total contribution is calculated by multiplying contribution per unit by the number of units sold.

Total Contribution = Contribution per Unit × Units Sold

This amount helps cover fixed costs and generate operating profit.

If fixed costs remain unchanged, maintaining total contribution also maintains operating profit under the same assumptions.

3. How Much Sales Volume Can You Afford to Lose?

Imagine a business selling 1,000 units per month.

Each unit sells for $20 and has a variable cost of $12.

The business is considering increasing its selling price to $22.

At the current price, each unit generates $8 in contribution.

At the proposed price, each unit would generate $10.

The higher contribution means the business may be able to sell fewer units while maintaining the same total contribution.

But how many fewer?

Let's calculate the sales volume required after the price increase and compare several possible customer-demand outcomes:
