Ingredient Price Increase Impact Tool

Enter the ingredient name, your current purchase price per unit, the new supplier price, and your average monthly usage in the same unit. The calculator shows the monthly and annual cost increase, the new food cost percentage for affected dishes, and the menu price adjustment needed to maintain your current margin.

Enter current price, new price, and monthly usage to calculate the cost impact of a price increase.

Cost impact estimates are based on the prices and usage quantities you enter. Actual costs depend on your specific usage patterns and purchasing arrangements. This is not financial advice.

How to use this tool

  1. 1Enter the ingredient name and the unit it is purchased in (per kg, per litre, per case).
  2. 2Enter the current price per unit from your existing supplier invoice.
  3. 3Enter the new price per unit from the supplier's updated pricing.
  4. 4Enter your average monthly usage in the same unit.
  5. 5Read the monthly and annual cost impact, and see the equivalent price adjustment across your menu to fully pass on the increase.

Formula used

Monthly cost increase = (new price - current price) x monthly usage. Annual cost increase = monthly cost increase x 12. Required price increase on menu = monthly cost increase / (gross margin % x monthly covers). New food cost % = new ingredient cost / current selling price x 100.

Example

Chicken breast: current 5.20/kg, new 6.40/kg, monthly usage 180kg

Cost increase per kg: 1.20. Monthly impact: 216. Annual: 2,592. To recover this fully through menu pricing across 1,800 covers per month, you need approximately 0.12 per cover increase in average menu price, or a targeted price increase on chicken dishes.

Olive oil: current 4.50/litre, new 7.20/litre (60% increase), monthly usage 40 litres

Cost increase per litre: 2.70. Monthly impact: 108. Annual: 1,296. While the percentage increase is dramatic, low monthly usage limits the absolute impact. The operator should audit how many dishes use significant amounts of olive oil and whether a different oil can substitute for cooking without affecting quality.

Common use cases

  • Calculating the actual profit impact of a supplier price increase before deciding whether to accept, renegotiate, or switch suppliers
  • Building a business case for a menu price increase by showing the specific cost drivers
  • Comparing the impact of price increases across multiple ingredients to prioritise which ones require immediate action
  • Estimating the cost of annual food cost inflation across your full ingredient list
  • Deciding whether to substitute an ingredient, change a recipe, or pass the cost on to customers

Common mistakes

  • Accepting a price increase without calculating the actual impact first - even small increases on high-volume ingredients add up to significant annual costs.
  • Not considering alternative suppliers or substitute ingredients before accepting the new price.
  • Passing on 100% of every increase immediately without considering the customer impact - sometimes absorbing a small increase is better than a visible menu price change.
  • Forgetting that a price increase affects every dish that uses the ingredient - total impact is much larger than the increase on a single item.

Frequently asked questions

Should I always pass on ingredient price increases to customers?

Not necessarily. Small increases on low-volume ingredients are often better absorbed than communicated through visible price changes. Large increases on high-volume ingredients (proteins, dairy) are difficult to absorb and usually require action - either a price increase, recipe adjustment, or supplier change. Calculate the monthly impact first, then decide based on the scale.

How do I negotiate with a supplier against a price increase?

Ask for the reason for the increase (raw material, transport, energy). Request volume discount pricing if you can commit to larger orders. Compare against alternative suppliers' current pricing. Ask whether a 3-6 month price hold is possible. Show loyalty and payment reliability as negotiating chips. Having the actual cost impact calculated (from this tool) strengthens your position.

At what percentage increase should I consider switching suppliers?

This depends on the importance of the ingredient and your existing supplier relationship. For commodity ingredients (oils, dried goods), a 15-20% increase is usually enough to trigger a market comparison. For quality-critical ingredients (specialty proteins, specific produce), quality and consistency may outweigh moderate price differences.
