This chart shows total monthly cash outflow across the lease term, including upfront charges in month one and annual escalation adjustments.

Example Data Table

Property	Lease Type	Base Rent	Term	Escalation	Free Rent	CAM	Sq Ft
Westview Office Suite	Modified Gross	$2,500	24 Months	4%	1 Month	$300	1,100
Central Retail Unit	NNN	$4,400	36 Months	3%	2 Months	$520	1,850
Harbor Flex Space	Gross	$3,150	18 Months	2.5%	0 Months	$180	1,420

Formula Used

Escalated recurring charge: Monthly Charge × (1 + Annual Escalation)^{Year Index}

Monthly occupancy cost: Rent + CAM + Maintenance + Utilities + Insurance + Taxes + Parking

Month one cash outflow: Monthly occupancy cost + Security Deposit + Broker Fee + Legal/Admin Fee + Move-In Fee

Gross cash outflow: Sum of all monthly cash outflows across the lease term

Net lease cost excluding deposit: Gross cash outflow − Security Deposit − Tenant Improvement Allowance

Effective monthly occupancy: Net lease cost excluding deposit ÷ Lease Term

Annual cost per sq ft: (Effective monthly occupancy ÷ Square Feet) × 12

Present value cost: Σ [Monthly Cash Flow ÷ (1 + Monthly Discount Rate)^Month] − discounted allowance

Frequently Asked Questions

1. What does this leasing cost calculator measure?

It estimates the full cash impact of a lease. That includes rent, occupancy charges, escalation, concessions, upfront fees, and area-based efficiency metrics.

2. Why is net lease cost lower than gross cash outflow?

Net lease cost removes refundable deposit treatment and subtracts tenant improvement allowance. Gross cash outflow still reflects the full cash paid during occupancy.

3. How is free rent handled?

Base rent is set to zero during the selected concession months. Other expenses can still apply because many leases continue charging operational items.

4. What is annual escalation?

Annual escalation increases selected recurring charges after each twelve-month period. It helps model inflation, contractual bumps, and rising occupancy obligations.

5. Why include a discount rate?

A discount rate converts future lease payments into present-value terms. This supports better comparison between leases with different timing structures.

6. Is security deposit always a cost?

Not always. Deposits are real cash requirements, but they may be refundable. That is why this page shows both gross outflow and net cost views.

7. Can this calculator help compare two properties?

Yes. Run the calculator separately for each lease proposal, then compare effective monthly occupancy, present value cost, concessions, and annual area cost.

8. What costs should I verify before signing?

You should verify rent schedule, escalation clauses, CAM definition, tax sharing, insurance obligations, maintenance responsibilities, concessions, and deposit refund conditions.
