Every lease negotiation involves OpEx calculations
Operating expense pass-throughs are among the most negotiated provisions in commercial leases. Clear, accurate calculations benefit both sides of the table.
Every deal involves OpEx
Operating expense calculations are part of virtually every commercial lease negotiation. Getting them wrong starts the relationship on the wrong foot.
Structures vary widely
Gross, modified gross, triple-net, base year, expense stop. Each structure calculates tenant responsibility differently.
Both sides need the numbers
Landlords and tenants both model OpEx exposure. Currently done in ad-hoc spreadsheets with inconsistent assumptions.
What you can calculate
Gross, modified gross & triple-net
Calculate pro-rata share under any lease structure, from full-service gross to absolute triple-net.
Base year & expense stop
Model tenant exposure with base year stops, expense stops, and year-over-year escalation caps.
CAM, insurance & taxes
Break down operating expenses into individual components: common area maintenance, insurance, real estate taxes.
Year-over-year caps
Limit tenant exposure with controllable expense caps that restrict year-over-year increases to a defined percentage.
Building-wide calculations
Calculate pro-rata share based on rentable square footage as a proportion of total building area.
Gross-up provisions
Adjust operating expenses to reflect full occupancy, protecting landlords from vacancy-driven cost spikes.
