The Hidden Cost of Discounts

A small discount can remove a large share of your profit. Know the arithmetic before you offer one.

Discounts feel generous and harmless. A customer hesitates, you offer ten percent off, the sale closes and everyone seems happy. Yet discounts are one of the most expensive habits a small business can develop. They reduce profit far more than the headline percentage suggests, train customers to wait for lower prices and can quietly undermine the value of your work.

This does not mean discounts are always wrong. It means they should be used deliberately, with a clear purpose and an understanding of their true cost.

The arithmetic of discounting

Discounts are taken from your profit, not your revenue. Imagine a product sold for €100 that costs €60 to make and deliver, leaving €40 profit. A ten percent discount reduces the price to €90, but your costs remain €60, so your profit falls to €30. A ten percent discount has removed a quarter of your profit.

To earn the same total profit at the discounted price, you would need to sell about a third more units. Many businesses offer discounts without ever checking whether the extra volume appears.

Discounts change customer expectations

Customers learn quickly. If you frequently offer discounts, many will wait for the next one before buying. Some will ask for a discount every time, because it has worked before. Regular discounting can turn your full price into a number nobody actually pays.

Discounts can also send an unintended message. If a premium service is regularly reduced, customers may wonder whether it was overpriced in the first place.

Better alternatives to discounting

When a customer hesitates about price, a discount is rarely the only option:

  • Adjust the scope: offer a smaller package at a lower price rather than the same package for less.
  • Add value instead: include something inexpensive for you but valuable to the customer, such as a short training session.
  • Change payment terms: spread payments over several months while keeping the total price.
  • Offer a guarantee: reduce the perceived risk instead of the price.

Each alternative protects your price while addressing the customer's real concern.

When discounts make sense

Discounts can be useful when they serve a clear purpose. Examples include rewarding customers who pay a year in advance, offering a founding price to early customers who take a risk on a new product, clearing old stock or thanking long-term clients. In these cases, the discount buys something valuable: cash flow, commitment, early feedback or loyalty.

Define the purpose, limit the duration and communicate the reason clearly. A discount with a reason feels fair. A discount without a reason invites negotiation.

Set rules in advance

Decide your discount policy before you face a hesitant customer. What discounts are allowed, for whom, how large and under what conditions? Write it down. Clear rules prevent emotional decisions in the middle of sales conversations and ensure customers are treated consistently.

Measure the results

If you run a promotion, measure its effect: how many additional sales it produced, what profit it generated and whether customers returned at full price afterwards. Many promotions look successful because they increase sales, while actually reducing total profit.

An example in practice

A small online tea shop ran a twenty percent discount almost every month. Sales spiked during promotions and fell sharply between them. When the owner calculated the effect, she found that the promotions produced more orders but less profit than ordinary months. She stopped regular discounts, introduced a loyalty programme offering a free sample with every third order and kept one annual sale. Orders became steadier and profits improved within a quarter.
