Annual Household Utility Cost Calculator
Enter a representative monthly amount for each category in one currency. Enter 0 for categories you do not pay.
A QUICK WALKTHROUGH
How to use this tool
- Enter your monthly electricity, gas, water, and other utility costs.
- Assign each bill once; split a combined bill or put its full amount in one category.
- Confirm there is no overlap and review the annual total, daily average, and category shares.
Monthly bill amounts
Use one currency throughout; no currency conversion, tariffs, or default prices are supplied. If water is included in another bill, do not enter it again. For a combined bill, split the charges or assign the entire bill once.
Cost estimate
Annual total = monthly total × 12. Daily average = annual total ÷ 365. Category share = category monthly cost ÷ monthly total × 100; all shares are 0 when the total is 0. The estimate repeats the same monthly amounts for 12 months and uses 365 days. It does not predict seasonal changes, future prices, or your actual annual bill.
