Free rental commission calculator. Estimate broker fees, move-in costs, and effective monthly rent for apartments and commercial leases.
The Rental Commission Calculator estimates broker fees, total move-in costs, and effective monthly rent when renting an apartment or commercial space. Enter your monthly rent and fee structure to see the true cost of signing a lease, including broker commissions, security deposits, and upfront rent payments.
Broker fees can add thousands of dollars to move-in costs where they are still charged to the tenant, significantly affecting cash-on-hand at signing. But fee rules and local practices vary sharply by market. In New York City, for example, the FARE Act took effect on June 11, 2025 and generally prohibits landlords’ agents from charging broker fees to prospective tenants. This calculator therefore works best as a scenario worksheet: enter the fee structure you are actually being quoted, then see how that fee changes your effective monthly rent.
The lease length impact table is especially valuable — it shows how longer leases reduce the per-month cost of broker fees, helping you negotiate better terms. Compare different fee structures (months of rent, percentage of annual rent, or flat fee) to find the most cost-effective option.
Move-in costs can easily exceed 3-4 months of rent in broker-heavy markets. Use this calculator to compare broker fees, deposits, and lease lengths so you can budget the real upfront cost and negotiate better terms.
Broker Fee (Months) = Monthly Rent × Number of Months Broker Fee (%) = Monthly Rent × 12 × Percentage Total Move-In = Broker Fee + Security Deposit + Upfront Rent Effective Monthly = Monthly Rent + (Broker Fee ÷ Lease Months) Fee as % of Lease = Broker Fee ÷ (Monthly Rent × Lease Months) × 100
Result: Broker fee: $2,000 | Move-in: $6,000 | Effective monthly: $2,167
Broker fee: $2,000 (1 month). Deposit: $2,000. First month: $2,000. Total move-in: $6,000. Amortizing the $2,000 fee over 12 months adds $167/month to effective rent.
Broker fees come in three common structures: months of rent (typically 1 month), percentage of annual rent (10-15%), and flat fees (common in newer platforms). On a $2,500/month apartment, 1 month = $2,500, 15% of annual = $4,500, and flat fees average $1,000-$3,000. The percentage method costs significantly more at higher rents.
No-fee apartments aren't truly free — landlords typically build the cost into higher rent or receive applicants willing to pay more. A $2,000 no-fee apartment might be $1,850 with a 1-month broker fee. Over 12 months: no-fee costs $24,000, while the fee apartment costs $22,200 + $1,850 fee = $24,050. Nearly identical, but the fee apartment requires more cash upfront.
Commercial rental commissions work differently. Typical rates are 4-6% of total lease value, paid by the landlord. On a 5-year lease at $5,000/month ($300,000 total), the commission is $12,000-$18,000. Both tenant and landlord representatives earn commissions, and fees are usually split between them.

This page converts the user's entered fee structure into a single broker-fee amount using one of three formulas: months of rent, percentage of annual rent, or a flat fee. It then adds security-deposit months and upfront-rent months to show total move-in cash required, and it amortizes the broker fee across the lease term to show an effective monthly rent after fees.
It is a scenario worksheet rather than a local-law determination. Residential and commercial commission practices vary sharply by market, lease type, and who hired the broker, so users should enter the actual quoted fee structure and check current local law before assuming the fee is enforceable.
It varies by market, property type, and who hired the broker. Some rentals have no tenant-paid broker fee at all, while others quote a flat fee, one month of rent, or a percentage of annual rent. Commercial leasing commissions are often structured differently from residential fees.
Yes. In competitive markets (high vacancy), fees are more negotiable. Ask for reduced fees, landlord-paid portions, or fee spreading. Some brokers will reduce fees for quick closings or if you're a strong applicant.
Rules vary by jurisdiction. In New York City, the FARE Act took effect on June 11, 2025 and generally bars landlords’ agents from charging broker fees to prospective tenants. In other markets, commissions are often negotiable and depend on the listing agreement, local law, and who hired the broker.
Typically: first month rent, last month rent (sometimes), security deposit (1-2 months), and broker fee. Some landlords also require application fees ($25-$100) and credit check fees.
Longer leases amortize the broker fee over more months, reducing effective monthly cost. A $2,000 fee on a 12-month lease adds $167/month, but on a 24-month lease, only $83/month.
For residential rentals, generally no. For commercial leases, broker fees are a business expense and can be amortized over the lease term for tax purposes.
