Will a price increase improve the business?

The supplier invoice has gone up again. You have held your price because you do not want to lose regular customers, but the work is leaving less money to pay the rest of the bills. Raising the price feels necessary. Knowing how far to raise it is a separate question.

A higher price increases what you collect on each sale that still happens. Whether it improves the business also depends on how many sales remain, what they cost to deliver and whether discounts or extra service work absorb the increase. Start by putting those pieces together.

Look at what each sale leaves behind

Compare contribution before and after the change. Contribution is the selling price minus the cost that changes directly with one additional unit or service. Then calculate how many units can be lost before total contribution falls below the current result.

Compare the two prices on the same basis

Current contribution per unit equals current price minus direct cost per unit.

Current total contribution equals current contribution per unit multiplied by current units sold.

Proposed contribution per unit equals proposed price minus the direct cost expected after the change.

The units needed to preserve current contribution equal current total contribution divided by proposed contribution per unit.

The SBA uses the same contribution relationship in its single-product break-even formula. Mixed products, step costs, capacity limits, and changing direct costs require a wider model.

A $5 increase, worked through

A service sells for $50. The directly connected labor, materials, and transaction fees are $20. Contribution is $30 per sale. At 1,000 sales, total contribution is $30,000.

The proposed price is $55. Direct cost remains $20, so contribution becomes $35. The business needs about 858 sales to preserve the same $30,000 of contribution. That is roughly 14.2 percent fewer sales than before.

At 900 sales, the proposed price would produce $31,500 of contribution: 900 × $35. At 800 sales, it would produce $28,000. The higher price helps in the first case and leaves less contribution in the second, compared with the original $30,000. These are scenarios, not a forecast of how customers will respond.

The $30,000 is contribution, not final profit. Rent and other fixed costs still have to be covered. Nor is 858 sales the number needed to break even for the entire business; it is the rounded-up volume needed to preserve the original contribution under these assumptions.

This does not mean losing 14 percent of customers is harmless. Lower volume can affect repeat purchases, staff utilization, vendor terms, referrals, and the sales mix. The calculation identifies one boundary. It does not predict customer behavior.

Recheck the costs before trusting the result

• Card fees or marketplace commissions that rise with price
• Packaging, freight, or labor tied to each sale
• Discounts that customers use more often after the increase
• Commissions based on revenue
• Extra service recovery or customer support
• Different costs for different products, channels, or customer groups

Fixed expenses such as rent still matter to the business, but they usually do not belong in direct cost per unit unless the decision changes the fixed commitment. Keep the distinction visible.

Think through the purchase from the customer’s side

Imagine a restaurant reviewing the price of a popular dish. The ingredient cost matters, but so do portion consistency, waste, packaging for takeaway orders and the fees attached to different sales channels. The same menu price can leave different amounts depending on how the order is sold and delivered. This is a teaching example, not a claim about a particular restaurant.

Then consider the customer’s choice. Will a regular guest order the same dish, choose a cheaper one, visit less often or accept the change? The calculation cannot supply that answer. Review who buys, why they buy, available alternatives, and how the change will be communicated. Test the proposal with comparable transactions or a bounded customer group when practical. Record units, collected revenue, discounts, direct cost, refunds, and contribution after the change.

National price indexes provide context. The BLS Producer Price Index (PPI) includes thousands of specific indexes measuring prices received by producers. A broad index does not prove what this business should charge. The business still needs its own cost and demand evidence.

Choose what you will watch after the change

Use the price change calculator with one product, service, or clearly defined group. Enter the current price, proposed price, direct cost, and current volume. Review the contribution-preserving volume. Then write down what evidence would show that the price is helping or hurting the business.

Choose a review period that makes sense for how often people buy. Compare similar trading periods and record other changes—opening hours, a promotion, seasonality or a different product mix—that could affect the result. Keep the units sold, collected revenue, discounts, direct costs and refunds together so a rise in sales value does not conceal a fall in contribution.

Decide who will review the result and what would prompt another look. You may keep the price, adjust the offer or address a cost problem. The purpose of the review is to understand what changed, with enough detail to decide what comes next.
