Adjusting Prices When Your Cost Price Rises

Guide · approx. 3 min read

If the cost price rises and the sell price stays the same, your margin drops — often unnoticed. Knowing the chain lets you update prices quickly and correctly.

The 5-step calculation: when the cost rises, the whole chain shifts up to the gross price.

Why silent cost increases are dangerous

Suppliers often raise only individual items. If your sell price stays put, the cost increase eats straight into margin. Across many items that adds up to real money — without showing up in revenue.

Spotting affected items

The key is knowing where the cost price has changed since the last calculation. Comparing the calculated reference price with the current one surfaces exactly the items that need recalculating.

Update consistently

Instead of raising prices randomly, reapply your factor or 5-step calculation to the new cost price. Your margin stays exactly the same — traceably across the whole catalog.

Detect cost changes automatically

PriceCalc Pro flags products whose cost price has changed since the last calculation and computes the new sell price at the press of a button.

Frequently asked questions

How do I update prices after a cost increase?
Reapply your factor or calculation to the new cost price — this keeps the margin constant.
How do I find affected items?
Compare the last calculated reference price with the current cost. Where it differs, action is needed.
Do I have to change all prices at once?
No — but the longer you wait, the longer you sell at a reduced margin.
