How to calculate and compare an electricity bill
This Australian example takes you from a published tariff to an estimated bill using your IAMMETER interval energy. BillSave is a comparison tool, not a retailer invoice or settlement system.
Find an Australian electricity offer
Open Find Plans. Search by retailer or plan name, or add the leading characters of your NMI and a postcode to narrow the applicable network and location. Select a published tariff you want to calculate; you can keep up to five offers in the left sidebar.
Review the tariff and required parameters
Check the tariff structure, effective date, calculation quality and official source. Some offers need customer-specific information, such as a Network Tariff Code, BPEA assumption or Business GST treatment. BillSave shows a suggested value when one is available; confirm it or replace it with your actual value before calculating.
Sign in with IAMMETER
Open Run Bill and sign in through IAMMETER OAuth. The server uses the authorised Cloud connection to read your sites and interval energy. Your IAMMETER password is not entered into BillSave.
Load a site and choose the billing cycle
Select Load sites, choose the IAMMETER Site you want to analyse, and choose the billing-cycle month. BillSave uses the Site billing date where available, so a billing cycle does not have to start on the first day of a calendar month.
Confirm the meter phase mapping
Review each IAMMETER phase or channel before calculation. Map the normal main-supply import/export channels to Grid. Map a channel to Controlled Load only when it is a separately metered controlled-load circuit, such as an eligible hot-water circuit; this role is used for that circuit’s separate controlled-load tariff. If the Site has no independent controlled-load channel, do not assign one.
Calculate the bill
Select Calculate bill. BillSave loads or reuses the Site’s interval energy for the billing cycle, then applies the selected tariff’s daily supply charges, usage rates, TOU periods, tiers, solar feed-in credits and supported adjustments. Missing data or an unresolved required value is shown instead of silently being treated as zero.
Review the result and compare the effect
Review the estimated total, calculation quality, assumptions and bill breakdown. You can download the complete bill breakdown, energy intervals and audit JSON. To see how another tariff changes the same bill period, select more offers and use Compare Offers; all selected offers use the same Site and energy data.
