Work out what a commercial oven costs a small business to buy and to run. Enter the purchase price, the power, the hours, the electricity rate and the maintenance, then see your annual running cost and the five-year total cost.
Formula: annual energy cost = power x hours per day x days per week x 52 x electricity rate, and five-year total cost = purchase price + 5 x (annual energy cost + annual maintenance).
The sticker price is only part of what a commercial oven costs. A cheap oven that runs hot all day can cost more over five years than a dearer oven that sips power. This calculator adds the purchase price, the electricity and the maintenance into one annual figure and one five-year total, so you can compare ovens on the same basis.
Daily energy use = power in kilowatts x hours used per day. Annual energy use = daily energy use x days used per week x 52. Annual energy cost = annual energy use x electricity rate. Annual ownership cost = annual energy cost + annual maintenance + (purchase price / lifespan). Five-year total cost = purchase price + 5 x (annual energy cost + annual maintenance). The calculator assumes an electric oven running 52 weeks a year with no shutdown weeks, and it assumes energy use is flat across the hours entered, with no separate preheat or idle split. Installation, a ventilation hood, gas and financing are not included. A Type 1 exhaust hood for a gas oven can cost $15,000 to $40,000 installed, so add it separately if your oven needs one.
A small restaurant buys a $4,500 convection oven rated at 5 kilowatts. It runs 10 hours a day, 6 days a week, at $0.16 per kilowatt hour, with $400 a year of maintenance and a 10 year life.
As a second check, take a $2,000 oven at 3 kilowatts, running 8 hours a day, 5 days a week, at $0.14 per kilowatt hour, with $250 of maintenance and a 10 year life. Annual energy use is 6,240 kWh, the annual energy cost is $873.60, the annual ownership cost is $1,323.60, and the five-year total is $7,618. The same steps work for any electric oven, so try your own numbers in the tool above.
Hours per day move the energy cost the most, because energy is power multiplied by time. A 5 kilowatt oven running 10 hours a day uses 50 kWh a day, while the same oven running 6 hours uses 30 kWh, a saving of $1,664 a year at $0.16 per kilowatt hour. The electricity rate matters just as much. At $0.16 per kilowatt hour the worked example costs $2,496 a year in energy, and at $0.24 it costs $3,744, a difference of $1,248 a year for the same oven and the same hours. Oven size matters through power. A countertop oven at 1.5 kilowatts costs about $374 a year in energy on 6 hours a day, while a full-size oven at 8 kilowatts costs about $6,290 a year on 12 hours a day. Maintenance is the smallest part for most ovens, at $250 to $800 a year, but it grows with age, and a breakdown in a busy week can cost more in lost sales than in parts. Published prices put entry commercial convection ovens at $1,000 to $5,000, full-size single ovens at $5,000 to $15,000, and conveyor ovens at $5,000 to $30,000. Our small business commercial coffee machine lease cost calculator prices another kitchen machine the same way, from a monthly payment to a yearly total.
Buying on price alone is the most common mistake. A $2,000 oven and a $4,500 oven look $2,500 apart on the quote, but over five years the gap shrinks. The $2,000 oven in the second check costs $7,618 over five years, while the $4,500 oven in the worked example costs $18,980, a gap of $11,362, because the dearer oven is bigger, runs longer hours and uses more power. The fair comparison is two ovens doing the same job for the same hours. When the hours and the tariff are the same, the oven with the lower power rating and the lower maintenance usually wins, even if it costs more to buy. A rapid-cook oven at $18,000 can still pay for itself in 8 to 12 months in a high-volume kitchen, because faster cooking means more covers per hour and fewer remakes. For most independent restaurants and small chains, the sweet spot is $2,500 to $5,000, which buys commercial-grade build, fast heat recovery and a realistic 10 to 15 year life with regular service. Run both quotes through the tool above with the same hours, days and tariff, and the five-year totals will show which oven is really cheaper. Our small bakery ingredient cost calculator helps you price what goes into the oven, so the food cost and the oven cost can be planned together.
Check the power supply first. A full-size electric oven usually needs three-phase power, and upgrading the supply can cost more than the oven itself. Measure the space, including the clearance the maker requires around the oven and the room for the door to open. Ask the supplier for the power rating, the energy use per hour and the warranty terms in writing, and ask what the warranty excludes, because heating elements and door seals are often covered for a shorter time than the rest of the oven. Ask for a service plan price, since a yearly service visit keeps the thermostat accurate and catches a failing element before it ruins a service. Compare new and used ovens on the same basis. A used oven at $500 to $10,000 can look cheap, but an old element and worn seals can push the energy cost up and the remaining life down. Get the running cost in writing where you can, and run the numbers through the tool above before you sign. Our catering cost per person calculator helps you price the food the oven will cook, so the menu price covers both the ingredients and the oven.
Entry commercial convection ovens cost $1,000 to $5,000, full-size single ovens cost $5,000 to $15,000, and conveyor ovens cost $5,000 to $30,000. In the worked example, a $4,500 oven costs $2,496 a year in electricity and $18,980 over five years including purchase and maintenance.
A $5,000 oven running 10 hours a day draws $2,000 to $5,500 a year in energy alone, depending on its power rating and your tariff. In the worked example, a 5 kilowatt oven running 10 hours a day, 6 days a week, uses 15,600 kWh a year, which costs $2,496 at $0.16 per kWh.
Multiply the oven power in kilowatts by the hours it runs each day, then by the days per week and by 52 weeks, then by your electricity rate. A 5 kilowatt oven running 10 hours a day, 6 days a week, uses 15,600 kWh a year, which costs $2,496 at $0.16 per kWh.
No, this calculator is for electric ovens only. Gas ovens need a gas tariff and a BTU rating instead of kilowatts, and they usually need a Type 1 exhaust hood that costs $15,000 to $40,000 installed, so add those costs separately.
For most independent restaurants and small chains, $2,500 to $5,000 buys commercial-grade build, fast heat recovery and a 10 to 15 year life. A cheaper oven can cost more over five years if it uses more power or breaks down more often, so compare the five-year totals, not just the purchase prices.
It depends on the hours, the power rating and the tariff, but a mid-range oven usually pays for itself in 12 to 24 months through faster cooking, fewer remakes and lower labor, and high-volume kitchens can see payback in 6 months. This calculator gives the cost side of that comparison; the revenue side depends on your menu and your covers.
This is an estimate for planning. Actual oven costs come from the supplier and your electricity tariff, and installation, ventilation and gas costs are not included.
