Calculating Estimated Price

One Click Switch uses your actual electricity usage to calculate a more realistic estimated price, giving you clarity and confidence to compare energy plans.

One Click Switch is different than most comparison sites. We actually use your historical usage data to calculate an estimate of how much you’re likely to pay for the plans on our platform.

At a high level, the estimated cost for plans follows this basic formula:

[Usage Data] * [Plan Rates] - [Solar] - [Discounts/Credits] = Estimated Cost

  • Usage is applied to the rates of the plans
    • Supply charge (over the period of data available)
    • General and peak/off-peak/shoulder usage according to the plan and the usage data available
    • Controlled load usage according to the plan and the usage data available
  • This gives us estimated cost from usage
  • We then apply solar usage and deduct from the total
  • We then deduct any applicable discounts or credits
  • This gives us the estimated cost for each plan

Usage Data

You can provide your usage data for more accurate calculations in 2 ways:

1. Connecting to your provider (highest accuracy)

Usage consumption is accessed from your provider and gives the most accurate and personalised estimated cost, based on your actual usage patterns.

We access up to 12 months of electricity usage directly from your provider using CDR. You need to have been with your current provider at your address for a minimum of 3 months.

2. From a recent bill (medium accuracy)

Usage consumption is based on the bill details retrieved (or entered) from your bill. Because it is based on a limited time period, it can miss higher or lower usage in different seasons.

Plan Rates

The rates for each plan on our platform come from the trusted government website, Energy Made Easy, which electricity providers are obligated to provide their plans to.

The rates for your current plan (where available) come directly from your provider when we connect via CDR.

Solar

Solar generation feed-in credits are calculated based on available solar export in your usage data (from your provider or from your bill) and the solar feed-in tariff in the plan rates.

Discounts / Credits

Any applicable discounts or credits come from the plan data available.

Our calculations DO include:

  • Guaranteed discounts
  • Account credit incentives : These are applied pro-rata for the available usage data timeframe

Our calculations do NOT include:

  • Conditional discounts
  • Rebates, green energy or other credits

Estimated Cost

Taking all of those calculations into account, we’ll end up with an estimated cost for your current plan (where available) and an estimated cost for the plans on our platform, based on the available electricity usage data from your current provider or from the bill details entered, applied to the rates of each plan.

The estimates are inclusive of GST, and by default include guaranteed discounts and one-off credits. The estimates include solar generation feed in credits (if specified), and excludes conditional discounts, green energy, rebates or other credits, outstanding balances or partial payments made.

Estimates are rounded to the nearest $10 to keep things simple. They’re a guide only - your actual bills may be higher or lower depending on how much energy you use in the future, when you use it, and any changes your provider makes to prices.

Compared to your Current Plan

We also show the estimated savings or increase for the usage period (inc. GST).

The price difference is based on the estimated cost of your current plan, compared to the estimated cost of this plan. There are situations where we are not able to retrieve information about your current plan. In those cases, the estimates are still personalised to your actual usage patterns but we won’t be able to show the difference compared to your current plan.

The Quick Select Calculation

If you choose to use the Quick Select method, the usage consumption data is based on household size and suburb averages and is not personalised to your situation. You will choose a usage tier to give some personalisation based on your household size.

The usage period for the quick estimate is based on one year of benchmark usage with seasonal modelling applied.

The rest of the calculations are performed in the same way however solar credits are NOT included, and we will never have information about your current plan (or available savings) using the quick method.
