While some restaurant owners buy equipment based on excitement, smart operators measure financial impact first. Many hospitality entrepreneurs invest based on gut feeling, but don't know if new equipment or processes actually generate money. Here's how to calculate the ROI of efficiency improvements, so you can make well-informed decisions.
What is ROI and why does it matter?
ROI stands for Return on Investment and indicates how much return you get on an investment. For kitchens, this means: how much money does a new machine, process, or system generate compared to what it costs?
The ROI formula is:
ROI = ((Revenue - Investment) / Investment) × 100%
💡 Example:
You invest €5,000 in a new combi-oven that saves €2,000 per year:
- Investment: €5,000
- Annual savings: €2,000
- ROI after 3 years: ((€6,000 - €5,000) / €5,000) × 100% = 20%
Payback period: 2.5 years
Types of kitchen efficiency improvements
There are different categories of improvements you can calculate:
- Equipment: New ovens, slicers, dishwashers
- Processes: Better mise-en-place, standardized recipes
- Software: Digital recipe management, HACCP registration
- Energy: LED lighting, energy-efficient cooling
- Staff time: Task automation
Identifying costs and benefits
For a proper ROI calculation, you need to map out all costs and revenues:
Costs (one-time and ongoing)
- Purchase price of equipment or software
- Installation costs
- Staff training
- Maintenance and service
- Potential renovations
Revenue (savings)
- Time savings: Fewer staff hours × hourly wage
- Ingredient savings: Less waste, more precise portions
- Energy savings: Lower gas/electricity bills
- Quality improvement: Fewer complaints, higher revenue
💡 Example time savings:
A professional slicer saves 30 minutes of prep time per day:
- Savings: 0.5 hours × €18 hourly wage = €9 per day
- Per year (300 working days): €9 × 300 = €2,700
- Machine costs €3,500
Payback period: 1.3 years
ROI calculation by category
Equipment ROI
With new equipment, you calculate based on total lifespan. A combi-oven lasts 8-10 years, a slicer 5-7 years.
Formula: (Annual savings × Lifespan - Purchase price) / Purchase price × 100%
Software ROI
Digital tools have monthly costs but can deliver various savings:
- Less time on cost price calculation
- Better control over food cost
- Faster HACCP registration
💡 Software ROI example:
Recipe software costs €25/month and saves:
- 2 hours administration per week × €18 = €36/week = €1,872/year
- 1% better food cost through insight = €3,000/year at €300,000 revenue
- Total savings: €4,872/year
- Costs: €300/year
ROI: ((€4,872 - €300) / €300) × 100% = 1,524%
Energy savings ROI
LED lighting and energy-efficient equipment often have a quick payback period. But here's something most kitchen managers discover too late: energy prices fluctuate dramatically, so base calculations on your actual annual bills, not current spot prices.
⚠️ Note:
Always calculate with realistic energy prices. Use your last annual bill as a basis, not current spot prices which can fluctuate significantly.
Payback period vs. ROI
Besides ROI, the payback period is important:
Payback period = Investment / Annual savings
- Under 2 years: Very attractive
- 2-4 years: Good
- 4-6 years: Consider carefully
- Over 6 years: Often not interesting
Including risk factors
An ROI calculation is a forecast. Account for:
- Maintenance: Machines may break down sooner
- Technology: Software can become outdated
- Staff: Training takes time and money
- Revenue: Savings may fall short if revenue drops
⚠️ Note:
Calculate conservatively. Better a pleasant surprise than a disappointment. Use 80% of expected savings in your calculation.
Comparing ROI between options
Have multiple investment options? Compare them on:
- ROI percentage: Which delivers the most return?
- Payback period: Which pays back fastest?
- Risk: Which is least risky?
- Cashflow: How much money do you have available?
How do you calculate ROI of an efficiency improvement? (step by step)
Inventory all costs
Write down all one-time costs: purchase price, installation, training, renovations. Don't forget ongoing costs like maintenance, licenses, or extra energy.
Calculate annual savings
Work out how much you save per year from the improvement. This can be time savings (hours × hourly wage), ingredient savings, energy savings, or revenue increase.
Determine lifespan
Estimate how long the investment will last. Equipment typically 5-10 years, software often shorter due to updates. This determines how many years you can calculate the savings over.
Calculate the ROI
Use the formula: ((Total savings over lifespan - Total investment) / Total investment) × 100%. Also check the payback period: investment divided by annual savings.
Add a risk buffer
Subtract 20% from your expected savings for unforeseen circumstances. This gives a more realistic picture of the actual ROI you can expect.
✨ Pro tip
Track your actual ROI results for 18 months after each major equipment purchase - you'll quickly spot which vendor promises hold true. Most operators find their time-saving estimates are 30% too optimistic.

Frequently asked questions
Should I include VAT in my ROI calculation?
Calculate with amounts excluding VAT if you can reclaim VAT. For most hospitality businesses: calculate excl. VAT because you can offset VAT on investments with the tax authority.
How do I convert time savings to euros?
Multiply the saved hours by the hourly wage including employer contributions. For kitchen staff, you typically calculate around €18-22 per hour all-in, depending on experience and collective agreement.
What if the savings are uncertain?
Create three scenarios: pessimistic, realistic, and optimistic. If even the pessimistic scenario delivers acceptable ROI, the investment is probably wise. Always err on the conservative side for your base calculations.
