Price increase calculator: when supplier prices rise
Price rise (%) = (New price − Old price) ÷ Old price × 100. A kilo of pistachios going from ₺1,100 to ₺1,300 is up 18.2%, so a cheesecake with 40 g costs ₺8 more: quantity used × increase per unit. To keep your margin, the new price is New cost ÷ (1 − Margin); to keep your ₺ profit, it's New cost + Old profit.

How it's worked out
(New buying price − Old buying price) ÷ Old buying price × 100
Quantity used × (New unit price − Old unit price)
Same margin: New cost ÷ (1 − Old margin) · Same ₺ profit: New cost + Old profit per item
How to use it
- Choose the unit your supplier prices it in: kg, litre or piece.
- Enter the old and new buying price for that unit; if the pack got smaller, convert to a price per kilo first.
- Enter how much one product uses: grams if you chose kg, millilitres if you chose litres.
- Add the product's cost before the rise and its current selling price.
- Read the rise, the extra cost per item and the margin left, then compare the two new prices: one keeps your margin, the other your ₺ profit.
Watch out
- A rise doesn't pass through one to one: an 18.2% rise in pistachios lifts this cheesecake's cost by 10%, because pistachios are only part of it.
- A smaller pack is a price rise too: 800 g for what 1 kg used to cost is 25% more per kilo.
- Don't wait for old stock to run out; what replaces it comes at the new price, so work from today's purchase.
- One ingredient often goes into several products, so check each of them; if you don't know a product's full cost, start with the recipe cost calculator.
Frequently asked questions
How do you calculate a percentage price increase?
Subtract the old price from the new one, divide by the old price and multiply by 100. An ingredient that went from ₺1,100 to ₺1,300 per kg rose 200 ÷ 1,100 × 100 = 18.2%. To find a new price from a percentage, multiply the old price by (1 + the rise): ₺1,100 × 1.182 ≈ ₺1,300. Always compare like with like: per kilo, per litre or per piece.
How do back-to-back price rises add up?
You multiply them rather than add them, because each rise lands on top of the last. Two 10% rises in a row make 21%, not 20%: 1.10 × 1.10 = 1.21. Three separate 3% rises stack up to 9.3%. The quickest check is to compare your first and latest buying prices: (Latest price − First price) ÷ First price × 100.
What does it cost me if I don't pass a rise on?
Multiply the extra cost per item by how many you sell a month. If a cheesecake now costs ₺8 more and you sell 300 a month, holding your price costs you ₺2,400 a month, and your margin slips from 60% to 56%. You can choose to absorb that for a while, but set an end date and count the other products that use the same ingredient.
Should I keep the same margin or the same profit?
Either can be right; it depends on your situation. Keeping the margin passes the cost rise through as a percentage: in the example, the price goes from ₺200 to ₺220. Keeping the ₺ profit adds only the cost difference: ₺208. If rent and wages are rising too, keeping the margin is safer; if only one ingredient went up and your customers are price-sensitive, keeping the ₺ profit may be enough.
