Why year-one rent isn't the number that matters
Most commercial tenants budget from the quoted base rent. The landlord says $8,000/month — that's the number that goes into the spreadsheet. But in a 5-year NNN lease with a 3% annual escalation and CAM charges that grow 5% per year, year one and year five look nothing alike.
On a $8,000/month base lease with $2,000/month CAM at typical escalation rates: year one you're paying $10,000/month. Year five you're paying over $12,500/month. Over the full five years, total occupancy cost is around $665,000 — not the $600,000 you'd calculate from year-one rent times 60 months.
That gap is what this calculator surfaces. The number that matters for your business isn't year-one rent — it's total occupancy cost over the full term, and what your monthly check will look like in year four when you're locked in.
