Interacting measure savings calculator

Subtract a separately established positive overlap from two standalone savings estimates; do not assume all interactions reduce savings or invent an overlap without analysis.

Scombined=S1+S2−IoverlapS_{\text{combined}} = S_{1} + S_{2} - I_{\text{overlap}}

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Worked example

Given

  • S1S_{1} = 55,000 kWh
  • S2S_{2} = 30,000 kWh
  • IoverlapI_{\text{overlap}} = 12,000 kWh
Scombined=55,000+30,000−12,000=73,000S_{\text{combined}} = 55{,}000 + 30{,}000 - 12{,}000 = 73{,}000
