About Triple Net (NNN)

In a Triple Net lease, you pay base rent plus your pro-rata share of all operating expenses — property taxes, insurance, and CAM. Budget for 20–40% of base rent in NNN charges. CAM reconciliations occur annually.

Assumptions & Disclaimers: This calculator provides estimates for planning purposes only. Actual lease costs may vary based on specific lease language, CAM reconciliations, landlord interpretations, market changes, and other factors. TI allowance is shown as a landlord-provided concession (not a cash cost to tenant). Free rent is assumed to apply in month 1 of the lease. Consult a commercial real estate attorney and tenant rep broker before making any lease commitments.
