While most restaurant owners focus on upfront equipment costs, smart operators calculate how quickly those investments pay for themselves. A €15,000 combi-oven might seem expensive until you realize it saves €800 monthly. The payback period reveals the real financial impact of your equipment decisions.
What is payback period?
Payback period shows how many months it takes for equipment to earn back its cost through savings or extra revenue. It's the simplest way to compare different investments and decide what's worth buying.
Payback period formula:
Payback period = Investment amount ÷ Monthly savings
💡 Example:
You're eyeing a new energy-efficient fryer for €8,000. It saves:
- Energy: €200/month
- Maintenance: €50/month
- Oil (less frequent changes): €80/month
Total savings: €330/month
Payback period: €8,000 ÷ €330 = 24.2 months
Which costs and savings do you include?
You need to capture every financial impact, both what you spend and what you save.
Investment costs:
- Equipment purchase price
- Installation costs
- Staff training
- Any renovations needed
Monthly savings:
- Lower energy costs
- Reduced maintenance
- Time savings (labor costs)
- Less waste
- Higher quality → increased revenue
⚠️ Note:
Only count concrete, measurable savings. "Better quality" matters only if you can actually charge more or sell more dishes.
Calculate different scenarios
Always run multiple scenarios to understand your risks. From tracking this across dozens of restaurants, conservative estimates usually prove more accurate than optimistic projections.
💡 Example combi-oven €15,000:
Conservative scenario (energy savings only):
- Savings: €400/month
- Payback period: 37.5 months
Optimistic scenario (energy + time + quality):
- Savings: €800/month
- Payback period: 18.8 months
When is an investment worthwhile?
Here's what works in hospitality:
- Excellent: Payback period under 18 months
- Good: 18-36 months
- Risky: 36-60 months
- Avoid: Above 60 months
Consider the equipment's lifespan too. A machine lasting 10 years can justify a longer payback than one needing replacement after 5 years.
Additional factors to consider
Financing: If you're financing the equipment, subtract monthly interest from your savings.
Depreciation: For accounting, you can depreciate equipment, creating tax benefits.
Maintenance: New equipment typically costs less to maintain than aging machines.
💡 Example financing:
Combi-oven €15,000 over 5 years, 4% interest = €277/month
Savings €800/month - €277 financing = €523 net savings
Net payback period: €15,000 ÷ €523 = 28.7 months
How do you calculate payback period? (step by step)
Calculate total investment
Add up all costs: purchase price, installation, training, and any renovations. Don't forget VAT if you can't reclaim it.
Determine monthly savings
Calculate how much you save per month on energy, maintenance, labor costs, and waste. Only include concrete, measurable savings.
Divide investment by savings
Use the formula: Investment amount ÷ Monthly savings = Payback period in months. Also calculate a conservative scenario.

Frequently asked questions
Should I include VAT in the calculation?
Yes, if you can't reclaim the VAT. Most hospitality businesses can offset VAT, so calculate using the price excluding VAT.
What if the savings are uncertain?
Always run a conservative scenario with only guaranteed savings. If that looks attractive, the investment is safer.
What's a realistic payback period for kitchen equipment?
Under 18 months is excellent, 18-36 months is solid. Above 36 months gets risky unless the equipment lasts exceptionally long.
Should I factor in financing costs?
Absolutely. Subtract monthly interest and payments from your savings to get the real payback period.
How do I account for equipment that might break down?
Consider expected lifespan carefully. A 10-year machine can justify longer payback than something lasting 5 years.
What if I'm comparing equipment with different energy ratings?
Calculate energy savings based on your actual usage hours and local utility rates. A 20% efficiency gain means different savings for a breakfast spot versus a 24-hour diner.
Should I include potential revenue increases in my calculations?
Only if you can quantify them realistically. Faster cooking times that let you serve 10% more customers during rush periods count, but vague "quality improvements" don't.
