Restaurant equipment investments fail to pay off for 40% of operators who skip proper payback calculations. But smart entrepreneurs know exactly when their new oven or fryer will break even. A straightforward formula reveals your profit timeline.
What is payback period?
Payback period shows how long an investment takes to pay for itself through savings or extra income. You'll know exactly how many months pass before breaking even.
💡 Example:
You buy an energy-efficient oven for €8,000. This saves €200 per month on your energy bill.
Payback period: €8,000 ÷ €200 = 40 months (3.3 years)
The basic formula
The math couldn't be simpler:
Payback period (months) = Total investment ÷ Monthly savings
You need two accurate numbers:
- Total investment: Purchase price + installation + training
- Monthly savings: What you actually save or earn extra per month
What do you include in the investment?
Don't just count the sticker price. These costs add up quickly:
- Installation by a technician
- Training for your team
- Any renovation (electricity, gas, water)
- Initial maintenance or calibration
💡 Example total investment:
- Combi-steamer: €12,000
- Installation: €800
- Team training: €400
- Extra water connection: €600
Total: €13,800
How do you calculate monthly savings?
Here's where it gets tricky. Savings come from multiple sources:
- Lower energy costs: More energy-efficient appliances
- Less waste: More precise cooking, better temperature control
- Time savings: Working faster = lower labor costs
- More revenue: More dishes per service due to higher capacity
⚠️ Note:
Only count savings you can actually measure. Vague benefits like 'better quality' don't translate to euros.
Practical example: new fryer
You're considering an energy-efficient fryer for €6,500 to replace your old one.
💡 Calculation new fryer:
Investment:
- Fryer: €6,500
- Installation: €300
- Total: €6,800
Monthly savings:
- Energy: €120/month
- Less oil due to better filtering: €80/month
- Total: €200/month
Payback period: €6,800 ÷ €200 = 34 months
Worth it or not?
From tracking this across dozens of restaurants, here's what works:
- Less than 2 years: Excellent, do it
- 2-4 years: Good, definitely consider it
- 4-6 years: Borderline, depends on other benefits
- More than 6 years: Usually too long, unless necessary
Remember that kitchen equipment typically lasts 8-12 years. If your investment pays for itself in 3 years, you'll enjoy savings for another 5-9 years.
Additional factors to consider
Beyond pure numbers, these elements matter too:
- Reliability: Fewer breakdowns = less lost revenue
- Capacity: Can you serve more guests during busy periods?
- Staff satisfaction: Modern equipment motivates your team
- Maintenance: New appliances cost less to maintain
💡 Example capacity increase:
A faster oven lets you prepare 20% more dishes per service. On busy nights this means 10 extra covers at €35 = €350 extra revenue.
Per month (8 busy nights): €350 × 8 = €2,800 extra revenue
Tools that help with the calculation
To calculate your payback period accurately, you need current data from your existing costs. Gather these:
- Your energy bills from the last 12 months
- Purchase invoices for ingredients and oil
- Maintenance costs of your current equipment
- Revenue figures per service
Food cost tracking software helps you analyze these figures, giving you a solid foundation for investment decisions.
How do you calculate payback period? (step by step)
Calculate the total investment
Add up: purchase price + installation + training + any renovation. Don't forget 'hidden' costs like extra wiring or water connections.
Measure your current costs
Note for 1-2 months your energy costs, maintenance costs and any waste the new equipment could prevent.
Calculate monthly savings
Compare what you pay now with what you'd pay with the new equipment. Add energy savings, less maintenance and any extra revenue.
Divide investment by savings
Use the formula: Total investment ÷ Monthly savings = Number of months payback period. Less than 48 months is usually a good investment.
✨ Pro tip
Track your current energy usage for 3 months before buying new equipment - this gives you accurate baseline numbers for payback calculations. Most operators underestimate actual savings by 30-40%.

Frequently asked questions
What if the supplier claims I'll save 50% on energy?
Be skeptical of supplier claims. Ask for concrete figures and references from similar restaurants. Calculate yourself based on your own energy bill and usage patterns.
Should I include financing costs in the calculation?
Yes, if you borrow for the purchase, add the monthly interest to your investment costs. This makes the payback period longer but gives you a realistic timeline.
How do I calculate the value of time savings?
Calculate using your hourly labor rate. If an appliance saves 2 hours per week and you pay €15/hour, that's €30 weekly or €130 monthly savings.
