Utility bills calculator
Adds up metered utilities and fixed charges into one monthly total.
Fill in the fields and the result will appear here automatically.
Sum each service’s consumption for the selected month times its unit tariff, then add fixed charges. Every line needs a name, usage and tariff: the last two numbers are usage and price, and preceding text is the name. Enter period consumption, meaning the difference of meter readings, rather than a cumulative reading. Variable and fixed parts remain separate so unit errors or duplicate fees are visible.
How it works
Formula and logic
Each nonblank line needs a service name and two numbers: usage u and tariff p. The last two tokens are read; everything before them is the name. Spaces or semicolons separate tokens; a dot or comma inside a number is decimal, with no thousands separators. Metered sum=Σu×p; total adds fixed charges. Year=12 identical months; service percentages are not rendered. Use one currency and one tax basis throughout.
Example
Electricity, water and gas at 2,023 plus 1,200 of fixed charges come to 3,223 a month. Line “water 0 6” with fixed charge 0 gives 0.00 for both month and year.
Fields and units
- Services: name, usage and tariff per line — name; usage in service units; tariff in monetary units per matching service unit
- Fixed charges per month — $
How to use
- — Enter “Name usage tariff”; decimal dot or comma is accepted, but do not use thousands separators.
- — The last two numbers on the line are the usage and the price per unit.
- — Put charges without a meter into the fixed field.
- — Compare the metered part with the fixed part in the result.

FAQ
What counts as a fixed charge?
Anything billed the same every month regardless of use: building maintenance, waste collection, the entryphone, a rented meter. They have no usage and no tariff, so they do not belong in the table.
Which units should usage be in?
Whatever the tariff is per. If electricity is priced per kWh, enter kilowatt-hours; if water is priced per cubic metre, enter cubic metres.
How do I enter a two-rate electricity meter?
As two lines — day and night — each with its own usage and tariff. The table will show which of the two costs more.
Why is the yearly figure just twelve times the month?
Because it is a projection of this month, not a forecast. Heating and air conditioning make real years uneven; the calculator does not pretend to know your season.
Is this the same as the electricity usage calculator?
The other tool estimates energy from power and hours. This one uses known period consumption—the difference of readings—and its tariff. Do not substitute the cumulative meter reading for usage.
