Net Metering Calculator
Estimate your annual true-up — a banked surplus payout, or a deficit owed.
This models your full annual true-up balance. Want the dollar value of just one month's exported solar instead? See the Net Metering Value Estimator.
This tool provides a planning estimate based on the assumptions shown below the results — it is not a quote, and actual costs and savings will vary by installer, local rates, and your specific home. Net metering vs. net billing rules vary significantly by state and utility — confirm your specific program before relying on these numbers.
Enter your annual production and consumption to see your year-end position.
How this calculator works
Net kWh for the year = annual production − annual consumption. A surplus is typically paid out at a lower annual true-up (avoided cost) rate rather than the retail rate; a deficit is billed at the retail rate like any other grid electricity. This models the annual banking cycle — for a single month's export value under net metering vs. net billing, see our Net Metering Value Estimator.
