Use these pages for quick answers to common cost questions, then jump into the calculator or comparison that best matches your case.
How much does a space heater cost per month?
A space heater can look cheap to buy and still become one of the fastest ways to raise an electricity bill. The real monthly cost depends on wattage, runtime, and your price per kWh.
Is a dehumidifier expensive to run?
A dehumidifier often runs for long periods, so the answer depends less on wattage alone and more on how many hours it stays active in your climate and room conditions.
How much does a mini split cost to run?
Mini splits are usually more efficient than direct electric heating and many portable cooling options, but the bill impact still depends on size, runtime, and tariff.
How much does a dishwasher cost per cycle?
Dishwasher cost per cycle depends on the program, energy use, and your tariff. The number can be low per cycle and still add up over months if the appliance runs often.
How much does a gaming PC cost per month?
A gaming PC does not only depend on the power supply label. Real monthly cost depends on actual gaming load, session length, and how often the machine stays on outside play time.
How much does a portable air conditioner cost per month?
A portable air conditioner can cool a room quickly, but it can also become one of the bigger summer electricity costs if it runs for many hours each day.
How much does it cost to charge an EV at home?
Home EV charging cost depends on charger power, charging hours, battery habits, and especially your tariff. The number can look low per session and still become a major monthly line.
Are mini fridges expensive to run?
Mini fridges look small, but that does not always mean cheap to run. Estimate the cost of running a mini fridge, dorm fridge, or small refrigerator across a day, month, and full year.
Does a bigger TV use more electricity?
Bigger TVs usually use more electricity, but the real question is whether the difference is meaningful enough to matter across a year of daily viewing.
Is an air fryer expensive to use?
An air fryer often uses high power for short periods. The real cost question is whether those short sessions add up less than using a full oven for the same food.
How much does a 7 kW wallbox cost to run?
A 7 kW wallbox can move a lot of energy in a short session, so the true cost depends less on the charger label and more on how often and when you charge.
Is electric underfloor heating expensive to run?
Electric underfloor heating can feel efficient because the comfort is even, but large heated areas and long winter schedules can still make the running cost substantial.
How much does a ceiling fan cost per month?
Ceiling fans usually look cheap to run, but the monthly number still depends on motor size, daily summer runtime, and whether they replace heavier cooling.
Does a heat pump water heater save electricity?
A heat pump water heater can look more expensive upfront, but the operating cost can be much lower than a standard resistive electric water heater if usage is steady.
Is a fan cheaper than a portable air conditioner?
A fan and a portable air conditioner solve different comfort problems, but the electricity gap between them can be large enough to matter before you buy.
How much does a small fridge cost to run?
A small fridge can look cheap to run, but many compact models are less efficient than people expect. The real cost depends on wattage, runtime, room temperature, and tariff.
How much electricity does a projector use?
Projector electricity consumption depends on brightness, image mode, lamp or LED system, and how many hours the setup runs per week. The useful question is the real viewing cost, not only the wattage on the box.
How much power does a 55-inch TV use?
A 55-inch TV does not have one fixed power number. Real consumption depends on panel type, brightness, HDR use, and how many hours the screen stays on each day.
How much does a 1500W oil radiator cost to run?
A 1500W oil radiator can look more moderate than a fan heater, but long winter runtime still matters. The real question is how many hours it heats and what tariff you pay.
Does dry mode use less electricity than cool mode?
Air conditioner dry mode can feel cheaper because it focuses on humidity instead of full cooling, but the real answer depends on climate, compressor behavior, and runtime.
Appliance electricity cost calculator
Use this appliance electricity cost calculator to estimate running cost by watts, hours, cycles, and price per kWh. It is the shortest path from a rough energy question to a usable monthly or yearly number.
kWh cost calculator
This kWh cost calculator helps turn watts, hours, and electricity price into a daily, monthly, or yearly cost estimate. It is useful when a query is about kW, kWh, or what a device adds to the bill.
How much electricity does a 2000W heater use?
A 2000W heater is simple to understand on paper but expensive in practice when it runs for many hours. This page helps translate that wattage into cost per hour, day, month, and winter season.
How much electricity does a wine cooler use?
Wine cooler electricity use depends on size, temperature setting, insulation, and ambient room heat. It can look modest day to day and still add up over a full year because it runs continuously.
How much electricity does an induction hob use?
Induction hob electricity use changes with power level, pan size, cooking time, and how often you use boost mode. The practical question is the cooking cost per meal, week, and month.
How much does an espresso machine cost to run?
Espresso machine running cost depends on boiler power, warm-up time, number of coffees, and how long the machine stays on between uses. Small daily habits make a bigger difference than many people expect.
Best energy monitors for appliance electricity use
Energy monitors are the fastest way to move from an estimate to a real number. They are especially useful for always-on appliances, cooling devices, fridges, wine coolers, chargers, and gaming setups.
Best smart plugs for energy monitoring
Smart plugs with energy data are useful when you want both measurement and control. They are a strong next step for espresso machines, projectors, standby-heavy electronics, and schedules you want to automate.
Best EV smart chargers for home charging
A smart EV charger matters when charging is frequent enough that scheduling, off-peak control, and visibility into sessions can materially change your running cost.
