Energy Cost Planner

Energy Cost Planner shows what the electrical appliances in your home use and what that costs at your own tariff. List what you plug in, copy the unit rate and standing charge from your bill, and see an estimate per day, week, month and year. It is a calculator that works on your figures. The app contains no energy prices and never goes online, so nothing in it goes out of date and nothing you enter leaves your phone. YOUR HOME AND APPLIANCES • Create a profile for your home, or several homes • Add appliances with their power in watts, hours of use and days a week • Start from a list of common appliances with typical values, then correct them from the rating plate • Enter washing machines and dishwashers by kWh per cycle, and fridges and freezers by the kWh per year on their energy label • Allow for appliances that cycle on and off, such as fridges and heaters with a thermostat • Count standby power and the months in which an appliance is used at all YOUR TARIFF • Unit rate in pence per kWh and daily standing charge • Single-rate tariffs and day and night tariffs of the Economy 7 kind, with your own number of off-peak hours • Say how much of each appliance’s use falls in the cheaper hours WHAT YOU SEE • Estimated cost and kWh per day, week, month and year • Cost by category: heating, hot water, cooking, fridges and freezers, laundry, lighting, TV and tech • A chart of consumption month by month • Your biggest users at a glance COMPARE BEFORE YOU CHANGE ANYTHING • Scenarios: switch an appliance off, shorten its hours, move it to the night or price everything with a different tariff, and see the difference in pounds • Replacement calculator: the yearly saving from a more efficient model and the simple payback time of its purchase price CHECK IT AGAINST YOUR METER • Keep a log of meter readings, with one reading or separate day and night readings • See what you really used between readings next to what your appliance list predicts • A meter that has passed its highest number and started again is recognised EXPORT • A PDF report of your estimate • CSV tables of the summary, appliances, readings and scenarios for a spreadsheet • A backup file you can keep or move to another phone PRIVATE AND FREE • No account, no adverts, no in-app purchases, no tracking • Works without an internet connection • Your data stays on your device PLEASE NOTE All results are estimates worked out from the numbers you enter. They are not a bill, not a forecast of your bill and not financial advice. Savings and payback times are illustrations that assume prices and habits stay the same. Typical appliance wattages are starting values only; the rating plate or energy label of your own appliance is the better source. The app is independent and is not connected with any energy supplier or regulator. Questions or a mistake to report? Write to [email protected]
