Know what this estimate is based on
- Jurisdiction
- United States — state and local practice
- Scope and limitations
- Educational estimate only. U.S. real estate costs are local: property tax rates, transfer and recording taxes, title practice, who customarily pays which closing cost, and landlord-tenant rules all change by state and often by county or city. Agent commission is negotiable and, since the 2024 NAR settlement, buyer-agent compensation is negotiated separately rather than assumed. Only a lender's Loan Estimate, a title company's fee sheet or a signed contract binds a number.

How to use
- 01
Enter the monthly rent and how many days of it you owe in your first month.
- 02
Enter the deposit and any last month's rent required, both in months of rent.
- 03
Enter the broker fee as a share of a year's rent — the common quote in markets that have brokers.
- 04
Open Advanced options for the application and admin fees, pet deposit and rent, parking, and renters insurance.
- 05
Read the total, then the ledger: it separates what comes back, what is credited against rent you would owe anyway, and what is simply gone.
Formula
Everything due at signing, sorted by what happens to it. The prorated first month is the monthly rent divided by the days in that month, times the days you occupy. The deposit and last month are the rent times the months required for each. The broker fee is a share of a year's rent, so it is the monthly rent times twelve times the percentage. Pet rent and parking are prorated the same way as the first month. The total is the sum of all of it, and it is then split three ways that add exactly back to it: refundable, meaning the deposits; credited to rent, meaning the prorated month, last month and the prorated add-ons; and gone, meaning the broker, application and admin fees plus the insurance. Only the days-in-month field keeps its default, because it is a divisor — a zero broker fee, a zero deposit and no last month required are all real market conditions somewhere in the US, so those stay blank on purpose.
Example
A $1,900 rent, moving in with 13 days left in a 31-day month, one month's deposit, one month's last rent, a 12% broker fee, and the advanced defaults. Prorated first month: $1,900 / 31 x 13 = $796.77. Security deposit: $1,900. Last month's rent: $1,900. Broker fee: $1,900 x 12 x 12% = $2,736. Application fee: $50. Admin fee: $250. Pet deposit: $300. Pet rent and parking, prorated: $46.13. Renters insurance: $180. Total: $8,159 — 4.3 months of rent to move into a $1,900 apartment. Now the split that matters. $2,200 is refundable: the deposit and the pet deposit, back if you leave the place clean. $2,743 is credited against rent you would owe anyway. And $3,216 is simply gone the moment you sign — the broker fee alone is $2,736 of it, more than a month's rent for the work of unlocking a door. That $3,216 is why moving is expensive and why a $200 rent increase is usually worth accepting rather than moving to escape.
Definitions
- Security deposit
- Refundable money held against damage and unpaid rent. Capped and regulated by most states.
- Last month's rent
- Prepaid rent collected at signing. Not a deposit and not protected as one.
- Broker fee
- A fee to the agent who showed the unit, commonly 8% to 15% of annual rent where brokers are used.
- Application fee
- A charge to process a rental application and run a screening. Rarely refundable, capped in several states.
- Admin fee
- A charge for paperwork, common with large managers. Frequently negotiable.
- Pet deposit
- Refundable money against pet damage. Distinct from a non-refundable pet fee.
- Pet rent
- A recurring monthly charge for having a pet, typically $25 to $50.
- Prorated first month
- Rent for the part of the month you occupy after moving in.
- Refundable
- Money you get back if the unit is left clean and the rent is paid — deposits, not fees.
- Credited to rent
- Money that pays rent you would owe anyway, such as the prorated first month or last month's rent.
- Deposit alternative
- A monthly surety fee replacing a lump-sum deposit. Cheaper up front, more expensive overall, and never refunded.
- Move-in special
- A concession — a free month, a waived fee — offered to fill a unit. Worth asking about before negotiating the rent.
Good to know
Four months of rent to get the keys
The upfront cost of a lease is routinely three to five times the monthly rent, and on these inputs it is 4.3 — $8,159 to move into a $1,900 apartment. The components are unremarkable individually and startling together: a security deposit, last month's rent, a broker fee at 12% of the annual rent, prorated rent for the days before the first full month, an application fee, an administrative fee, a pet deposit, and renters insurance paid up front. None of them is unusual and most are negotiable only at the margins. The reason this matters more than the rent figure is timing: the whole amount is due before you have the keys, usually in certified funds, and frequently within 48 hours of approval. Households that budget carefully for the monthly rent and not at all for the entry cost are the ones who lose an apartment they qualified for.
Refundable, credited, and simply gone
The $8,159 splits three ways and the distinction matters enormously. About $2,200 is refundable — the security deposit and the pet deposit, which come back at move-out less any lawful deduction. About $2,743 is credited: last month's rent and the prorated first period are rent you would owe anyway, paid early. And $3,216 is gone for good — the broker fee, the application and administrative fees, and the insurance premium. That last figure is the true cost of entering the lease, and it is the one to compare against staying put when a renewal increase arrives. A $200 monthly increase is $2,400 a year; the unrecoverable cost of moving is $3,216 before a single box is packed. Movers, time off work and a utility connection fee push it higher still.
Broker fees are a regional accident
In most of the country, the landlord pays the leasing agent and the tenant pays nothing. In New York City, Boston and a handful of other markets, the tenant customarily pays a broker fee of one month's rent to 15% of the annual rent — on a $1,900 apartment at 12%, that is $2,736 for work performed largely on the landlord's behalf. New York changed this in 2025: the FARE Act now requires the party who hired the broker to pay the fee, which in most listings is the landlord. Boston has debated similar legislation. Where the fee is still charged, the two things worth knowing are that no-fee listings exist and are worth searching for specifically, and that the fee is occasionally split or waived on a unit that has been sitting. It is the single largest negotiable line in the whole move-in bill.
What states allow a landlord to hold
Security deposit caps are state law and they vary widely. Many states cap the deposit at one or two months' rent; a few cap it at one and a half; several — including Texas and Florida — set no statutory limit at all. Some states restrict last month's rent separately or count it toward the cap, which is why a lease asking for first, last and two months' deposit is unlawful in more places than landlords sometimes realise. Most states also require the deposit to be held in a separate account, some require it to be interest-bearing, and nearly all set a deadline for returning it — commonly 14 to 30 days after move-out, with an itemised statement of deductions. Check your state's cap before signing rather than after, because a deposit collected over the limit is recoverable but only by asking for it.
The monthly number is not the rent either
Ongoing cost on this lease is $2,010, not $1,900, because pet rent and parking are separate recurring charges. That pattern is normal and growing: pet rent of $25 to $75, parking of $50 to $300, amenity fees, valet trash, package-locker fees, and mandatory renters insurance or a monthly waiver in place of it. Some buildings also charge a monthly technology fee for internet you may not want. None of these appear in the listed rent, and several are added at lease signing rather than at listing. When comparing two apartments, build the full monthly figure for each — including a realistic utility estimate for the specific unit, which an older building with electric heat can push $150 a month above a newer one. The apartment with the lower rent is often not the cheaper apartment.
Frequently asked questions
How much cash do I need to rent an apartment?
Three to four times the monthly rent is the normal ask across the US once first month, deposit, last month and fees are counted. In broker markets like New York it can reach five or six. It is the number that stops more moves than the rent itself.
How much of it comes back?
The security deposit and any pet deposit, if the place is clean and the rent is paid. Everything else is either credited against rent you would owe anyway or gone for good. On these defaults, $2,200 of $8,159 is genuinely refundable.
Is last month's rent the same as a deposit?
No, and the difference matters. A deposit is held in trust and protected by state law, often in a separate account and sometimes with interest. Last month's rent is prepaid rent — a landlord can apply it as intended, but a court will not treat it as security for damage.
What is a broker fee and do I have to pay it?
A fee paid to the agent who showed you the apartment, commonly 8% to 15% of a year's rent in markets that use them. Whether the tenant or the landlord pays is local custom and negotiable — New York changed its rules in 2025 to shift most such fees to whoever hired the broker.
Are application fees refundable?
Generally no, and several states cap them — California limits them to a statutory amount adjusted annually, and others require an itemized receipt or a refund of the unused portion. Applying to five places at $50 each is $250 gone before you have a lease.
What is an admin or lease fee for?
Paperwork, in principle. In practice it is a charge large managers add because the market allows it. It is negotiable more often than people try, particularly on a unit that has been listed a while.
Can a landlord charge any deposit they like?
No. Most states cap the security deposit at one to two months' rent, several require it be held in an interest-bearing account, and most set a deadline to return it. The caps vary enough that it is worth checking your own state before agreeing.
What about pet deposits and pet rent?
A pet deposit is usually refundable; pet rent is not — it is a recurring charge of typically $25 to $50 a month. Some landlords charge a non-refundable pet fee as well. Service animals and assistance animals cannot be charged for under federal fair housing rules.
Do I need renters insurance before signing?
Most leases now require it, commonly with at least $100,000 of liability, and many landlords want proof before handing over keys. It costs $12 to $25 a month, which makes it the cheapest line on this page.
Can I negotiate any of this?
The admin fee, the last month's rent requirement and sometimes the broker fee, particularly on a unit that has sat empty. The deposit is usually fixed by policy or by state cap. Ask about a move-in special before you ask for a rent reduction — landlords protect the rent number more than the one-off fees.
What if I cannot raise the cash?
Some markets offer deposit alternatives — a small monthly fee instead of a lump sum, from a surety company. They solve a cash-flow problem and cost more over time, and the fee never comes back. Read whether you are still liable for damage; you usually are.
Should I budget anything beyond this?
Yes. Movers, a truck, utility deposits, and the furniture the last place had and this one does not. This page prices what the landlord asks for; the move itself is on top.
