Calculate total lease costs with annual escalation, per-sqft pricing, NNN expenses, and move-in costs. Compare escalation scenarios with year-by-year rent breakdowns.
Whether you're comparing an apartment lease or a commercial space, the advertised base rent is rarely the whole story. Annual escalations, parking, move-in charges, and commercial pass-through costs can materially change the total occupancy cost over the full term.
This calculator handles both residential and commercial lease types, projecting total lease cost year by year and separating base rent from add-on costs. For commercial leases, it can model property tax, insurance, and CAM charges when those items are passed through to the tenant.
The escalation comparison table is useful for negotiation because it shows how different annual increase rates compound over time. The year-by-year breakdown also makes the monthly payment path visible before the first increase takes effect.
Use this calculator when you need the full lease cost instead of just the advertised monthly rent. It is helpful for comparing gross versus NNN structures, testing escalation clauses, and seeing how a seemingly small rate change compounds over a multiyear term.
Year N Rent = Base Rent × (1 + Escalation Rate)^(N-1) Total Monthly = Base Rent + Parking + applicable commercial pass-through costs Total Lease Cost = Σ (Monthly Rent in Year × Months in Year) Price/Sqft = Monthly Rent ÷ Square Footage Due at Signing = 1st Month Rent + Security Deposit + Move-In Costs
Result: Total Lease Cost: $92,727 — Final Year Rent: $2,652/mo — $2.08/sqft
Year 1: $2,500/mo × 12 = $30,000. Year 2: $2,575/mo × 12 = $30,900. Year 3: $2,652/mo × 12 = $31,827. Total = $92,727. Per sqft = $2,500 ÷ 1,200 = $2.08.
Lease structures are not directly comparable unless you normalize the extra charges. A gross lease bundles most building expenses into the rent, while an NNN lease pushes taxes, insurance, and common-area costs back to the tenant. Modified gross sits somewhere in between. The only fair comparison is total occupancy cost.
A lease escalation percentage looks small in year one, but it compounds across the term. On a longer commercial lease, even a one-point reduction in annual escalation can save a meaningful amount over the full commitment, especially when the rent starts from a high base.
Tenants often focus on the quoted monthly rent, but free-rent periods, tenant-improvement allowances, parking charges, security deposits, and CAM reconciliation rules can matter just as much. Looking at the year-by-year breakdown helps identify where a landlord concession actually changes the economics of the deal.

This worksheet escalates the entered base rent once per lease year, applies that rent to the months that fall in each year of the term, and then adds parking plus any applicable commercial pass-through charges. Property tax, insurance, and CAM are included only for the commercial lease types that expose those costs separately, while gross-lease scenarios treat them as embedded in the quoted rent.
The output is a planning worksheet rather than legal or accounting advice. Real leases can use CPI-linked escalations, rent-free periods, expense stops, broker commissions, landlord concessions, or reconciliation rules that are outside this simplified model.
Residential: 2-5% annually (varies by market — rent-controlled areas may cap at 3-5%). Commercial: 2-4% annually or CPI-linked. NNN commercial escalation applies only to base rent; NNN costs adjust based on actual expenses. In HCOL markets, escalation can be 5-8%.
NNN (Net Net Net) means the tenant pays property tax, building insurance, and common area maintenance (CAM) in addition to base rent. Total NNN costs typically add $3-15/sqft/year depending on location. In a gross lease, these costs are included in the quoted rent.
Common Area Maintenance (CAM) covers shared space costs: lobbies, parking lots, landscaping, security, elevators. It's usually proportional to your share of the building's total square footage. If you lease 2,000 of 20,000 sqft, you pay 10% of total CAM costs.
A flat rate is always better for the tenant if you can get it. Landlords prefer escalation to keep up with inflation. If escalation is unavoidable, negotiate the rate down or cap it (e.g., "3% or CPI, whichever is lower"). On a 5-year lease, each 1% reduction in escalation can save thousands.
Residential: 1-2 months rent (legally capped in some states). Commercial: 2-6 months rent (less for established businesses, more for startups). Some landlords accept a letter of credit instead, preserving your cash for operations.
Gross lease: landlord pays taxes, insurance, and maintenance — the quoted rent is your total cost. NNN lease: tenant pays these costs separately (~$3-15/sqft/year extra). Modified gross: some costs included, some separate. Always compare total cost (base + NNN), not just base rent.
