Commercial Rent per Sq Ft Annualizer rent math, not a legal document

Annualize a commercial lease quoted the way brokers actually quote it — in dollars per square foot. Enter the price per sq ft (yearly or monthly), the leasable area, optional NNN add-backs, and a term to see the total annual base rent, monthly rent, full-service rent and a per-year schedule.

How this works & assumptions
This tool is rent math, not a legal document. It annualizes a commercial lease that is quoted on a dollars-per-square-foot basis — the standard retail, office and industrial quoting method — and nothing it produces replaces what is actually written in the lease.

Annual base rent = price per sq ft × leasable area, × 12 when the quote is monthly. Monthly base rent is the annual figure split into 12 equal payments (many leases bill it this way).

Load factor. When only the usable area is known, rentable area = usable × (1 + load factor). The quoted price and the per-sq-ft figures below are always on the rentable basis; the effective cost per usable sq ft is shown when a load factor is in play.

NNN add-back. Property tax, insurance and CAM are annual dollars the tenant reimburses on top of rent. Full-service rent = base rent + total NNN. The NNN figure spread back across the rentable area gives the add-back in $/SF.

Year schedule. The schedule holds NNN flat and applies the optional flat escalation to base rent each year as base × (1 + escal)year−1. Real NNN costs move every year with tax and CAMreconciliation — confirm actual figures with the landlord’s year-end statements.

Figures are estimates for analysis. Verify the lease documents with your broker or counsel before signing.
