Check If Your Price Still Covers a Cost Rise

You set a price, then a supplier raises the cost of one input. The old price may still cover it, or it may not. The question is whether the new unit cost fits inside the price you already chose.

Keep two numbers in front of you:

• The share of your unit price now taken by the input that rose.
• Your margin if you absorb the increase, and your margin if you pass it through.

The unit cost is the first number to recompute

Start with one unit, not the monthly invoice. Add the new input cost to every other cost that belongs to one unit: materials, labor, packaging, delivery, fees, and the overhead the unit actually uses. The result is a single number: one unit now costs you X, and that number is higher than the one you used when you set the price.

A mid-year price increase can look small on a bill, but the decision is made on one unit. If the cost of goods has gone up, the answer begins with the unit cost, not the total. The invoice tells you what you paid; the unit tells you what one sale costs.

On October 1, 2026, Samsung raised U.S. prices on most Galaxy S26 phones by $100 or more after AI infrastructure demand tightened memory supply. Seven months into the Galaxy S26 series' sale, the increases were $100 for the S26, S26+, and S26 Ultra, and $200 for the 1TB Ultra. The 1TB Galaxy S26 Ultra moved from $1,799 to $1,999.

The Galaxy S26 FE kept its $699 starting price through the latest S26 changes. The latest S26 adjustment left the Z Fold 8, the Z Fold 8 Ultra, and the Z Flip 8 prices unchanged.

The input's share of price shows the size of the hit

Divide the new cost of the input that rose by the current unit price. If the input now takes a larger slice of the price, your margin has shrunk even if the price has not changed. You get a percentage: the input now takes Y percent of the price, and you can see how much room is left for everything else.

This share is the first signal. A small dollar increase can be harmless if the input is a small part of the unit. The same dollar increase can be serious if the input is a large part of the unit. The dollar amount alone does not tell you the size of the hit. The share of the price does.

The Reserve Bank of Australia counts input-cost increases on the supply side as a separate driver of inflation. When the cost of domestic or imported inputs, including oil or raw materials, climbs, production costs rise. When per-unit production costs rise, firms often produce less and charge more.

The margin comparison decides whether to absorb or pass through

Absorbing means keeping the price the same and letting the unit margin fall. Passing through means raising the price by enough to restore the old margin, or by a smaller amount if you choose to keep some of the increase. You end with two margins: one lower, one restored or partially restored.

The Reserve Bank of Australia defines a firm's margin as the mark-up added to costs and treats demand-pull inflation, pressure from strong demand, as a source of room to lift prices and margins. When the pressure comes from higher input costs, that room may not exist. You may have to choose between a thinner margin and a higher price.

People often raise the price by the exact dollar increase in the input. That can be wrong. Do not match the supplier's increase line for line. If the input is a small share of the unit, a full pass-through may be unnecessary and can make the price change look arbitrary. If the input is a large share, the margin after absorbing it may be too thin, so a price change may be needed. Use the margin after the cost increase, not just the invoice line.

Samsung's memory business raised the quarterly contract price on a 12GB mobile DRAM unit, a phone memory chip, to about $70. In the first quarter, Samsung's semiconductor unit made 94% of the company's profit, while the mobile unit's operating profit fell by about 38%.

Choose the move that keeps the price defensible: hold, raise, or change the product. When the input's share of price is small and the margin after absorbing it is still acceptable, you can hold the price for a while. When the share is large and the margin after absorbing it is too thin, you need to reprice existing products. If the cost rise is temporary, a short-term price increase may be easier to explain than a permanent one.
