Net Metering Credit Calculator

Work out net metering credit instantly with clear inputs, formula shown and shareable results.

About Net Metering Credit Calculator

Self-consumed solar avoids the full import tariff; exported solar earns only the export credit, which is usually far lower. Because generation and consumption rarely coincide perfectly, only around 60-80% of solar output offsets load directly without storage or load shifting.

Formula

Net metering

Saving = consumption x import rate - (imported x import rate - exported x export credit)

Worked example

With the default values below, Net Metering Credit Calculator returns Monthly Bill Saving of $8,176.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why does self-consumption matter so much?

The value of a self-consumed unit is the import tariff, often two to three times the export credit. Shifting load into daylight hours can be worth more than adding panels.

What is the difference between net metering and net billing?

Net metering offsets exported units against imported units on a volumetric basis. Net billing values exports at a separate, usually lower, rate. The distinction changes project economics substantially.
