Calculate the effective rent after free rent concessions. See how free months reduce your average cost and total lease expense over the full term.
Free rent (rent abatement) is one of the most common concessions in commercial leasing. Landlords offer 1–6 months of free rent to attract tenants, especially during lease-up of new buildings, in soft markets, or for long-term leases. Understanding the value of free rent and how it affects your effective rate is essential for comparing proposals.
A 1-month concession on a 12-month, $3,000/month lease saves $3,000 and reduces your effective rent to $2,750/month — an 8.3% discount. On a 5-year lease, 3 free months reduces effective rent by 5% and saves $9,000.
This calculator computes your effective monthly rent and total savings from free rent concessions. It helps you compare lease proposals where one offers lower rent and another offers free months.
Homebuyers, investors, and real-estate professionals all benefit from precise free rent concession figures when evaluating properties, negotiating deals, or planning long-term investment strategies. Save this calculator and revisit it whenever market conditions or your financial situation changes.
Free rent months are worth thousands of dollars but can be hard to compare across offers with different lease terms. This calculator normalizes the concession into an effective monthly rate. Instant recalculation lets you compare scenarios side by side, so every buying, selling, or investment decision is grounded in solid financial analysis.
Total Rent Paid = Monthly Rent × (Lease Months − Free Months) Effective Monthly Rent = Total Rent Paid / Lease Months Total Savings = Monthly Rent × Free Months Discount % = Free Months / Lease Months × 100
Result: $4,750/mo effective rent (5% discount, $15,000 savings)
On a 60-month lease at $5,000/month with 3 free months, you pay for 57 months = $285,000 total. Effective rate: $285,000 / 60 = $4,750/month. You save $15,000 — equivalent to a 5% rent reduction.
Free rent is powerful leverage in commercial leasing. Landlords often prefer giving free months over reducing base rent because a higher base rent supports better property valuations and financing terms. Use this to your advantage: if the landlord won't lower rent by $2/sq ft, ask for 2–3 free months instead.
On a $30/sq ft NNN lease for 5,000 sq ft, 3 free months saves $37,500. Over a 5-year lease ($750,000 total), that's a 5% discount. But if you could have negotiated $1.50/sq ft lower base rent instead, you'd save $37,500 as well — with the added benefit of lower escalation in future years.
The most competitive deals combine free rent with TI and reduced escalation. In a tenant's market, it's reasonable to ask for all three. Quantify each concession's value to prioritize your negotiation agenda.
Typical concessions range from 1–2 months on a 3–5 year lease to 3–6 months on a 7–10 year lease. In weak markets or for large spaces, even more is possible. The landlord's loan covenants may limit how much abatement they can offer.
Usually yes. Most free rent concessions only abate base rent — you're still responsible for NNN charges (taxes, insurance, CAM). Negotiate "gross" free rent (including NNN) if possible, as this saves you $1,000–$3,000+ per month.
It depends on your time horizon and the landlord's pricing. Free rent provides immediate cash benefit but doesn't reduce future years' rent. Lower base rent saves more over long terms because escalation clauses compound from a lower base.
Most free rent is given at lease commencement to help with move-in costs. Some tenants negotiate spreading it over the first 12–24 months (e.g. half rent for 6 months instead of 3 free months). Spread-out abatement can help with cash flow.
Most leases have a "claw-back" provision: if you terminate early, you must repay the free rent (sometimes with interest). This protects the landlord from tenants who take free rent and leave. Review termination clauses carefully.
Free rent reduces the landlord's net effective rent and investment returns. Landlords prefer free rent over base rent reductions because the quoted rent stays higher (important for property valuation and refinancing). This is why they're often more willing to offer free months than rate cuts.
