Utility bill calculator
Your bill equals consumption (current reading minus previous reading) multiplied by your price per unit — works for electricity, gas or water meters.
Frequently asked questions
- Does this work for electricity, gas and water?
- Yes — the math is the same for any metered utility. Just use the price per unit your provider charges (per kWh, per m³, etc.).
- What if I have a multi-tariff meter (day/night)?
- Run the calculation separately for each tariff and add the results together. FinMan's bot handles multi-tariff meters automatically, including tariff changes over time.
Stop calculating this by hand every time
FinMan calculates this automatically every month and reminds you when a reading is due — just photograph the meter.
