Net Metering Savings Calculator

Background.

The practical question behind Net Metering Savings Calculator is whether you can value self-consumed solar at avoided retail price and exports at the applicable credit. In this context, self-consumption and exports often receive different tariff value, so one blended rate can overstate savings. The calculator therefore applies “monthly value = self-consumed kWh × avoided retail rate + exported kWh × applicable export credit.”

The editable entries are solar energy self-consumed, solar energy exported, avoided retail rate, applicable export credit. Use values from the document or measurement that governs this net metering savings question; the defaults are only the worked fixture below. Monthly true-up, fixed charges, time-of-use periods, credit expiration and utility-specific netting are excluded. That net metering savings boundary is part of the answer, not a generic disclaimer.

U.S. Energy Information Administration, Electricity explained—prices and tariffs documents the convention or governing rule used here. The net metering savings output is a transparent scenario under those facts: it does not manufacture an unentered market price, professional determination, carrier quote, legal eligibility finding or locally adopted code value.

What is net metering savings calculator?

Net Metering Savings is the relationship behind this decision: self-consumption and exports often receive different tariff value, so one blended rate can overstate savings. On this page it means monthly value = self-consumed kWh × avoided retail rate + exported kWh × applicable export credit. Monthly true-up, fixed charges, time-of-use periods, credit expiration and utility-specific netting are excluded; that is the line between the reported quantity and a broader building systems analysis.

How to use this calculator.

1. 01Confirm that “monthly value = self-consumed kWh × avoided retail rate + exported kWh × applicable export credit” matches the net metering savings convention you need.
2. 02Replace the fixture values for solar energy self-consumed, solar energy exported, avoided retail rate, applicable export credit with dated values from the governing record.
3. 03Keep all currencies, measurement units and time periods on the same basis before calculating.
4. 04Read monthly self-consumption plus export value together with this boundary: Monthly true-up, fixed charges, time-of-use periods, credit expiration and utility-specific netting are excluded.

The formula.

The calculation uses monthly value = self-consumed kWh × avoided retail rate + exported kWh × applicable export credit. In this net metering savings model, the entered terms are solar energy self-consumed, solar energy exported, avoided retail rate, applicable export credit. Self-consumption and exports often receive different tariff value, so one blended rate can overstate savings, which is why the relationship is presented under this name rather than as a universal alternative. Monthly true-up, fixed charges, time-of-use periods, credit expiration and utility-specific netting are excluded. Calculations keep full decimal precision through the relationship and round only the returned display values.
