Use this move-in cost calculator to add up first and last month’s rent, security deposit, broker and pet fees, and see the total cash needed to move in.
Move-In Cost Formula
The total cost to move into a rental is the sum of the up-front charges a landlord or property manager collects before you get the keys:
Move-In Cost = FM + LM + SD + BF + PF + AF + O
Variables:
- FM is the first month’s rent (prorated if you move in mid-month)
- LM is the last month’s rent, if the landlord collects it up front
- SD is the security deposit
- BF is the broker or finder fee
- PF is pet-related charges (pet deposit plus first pet rent)
- AF is administrative charges (application fee plus any move-in or admin fee)
- O is any other one-time cost, such as a key deposit, cleaning fee, or renters insurance set-up
When you move in partway through a month, the first month is usually prorated. The calculator charges only for the days you actually occupy the unit:
Prorated Rent = (Monthly Rent / Days in Month) * Days Occupied
Deposits are typically refundable when you move out and the unit is left in good condition, while fees are not. The calculator separates the two so you can see how much of the total you are likely to get back.
Typical Move-In Cost Components
Exact charges vary by city, building, and landlord, but most move-in bills are built from the same pieces. This table shows what each one usually looks like.
| Charge | Typical amount | Refundable? |
|---|---|---|
| First month’s rent | 1 month | No |
| Last month’s rent | 0 to 1 month | Applied to rent |
| Security deposit | 0.5 to 2 months | Usually yes |
| Broker / finder fee | 0 to 1 month (or 8-15% of annual rent) | No |
| Pet deposit / pet rent | $200 to $500 deposit | Deposit often yes |
| Application fee | $25 to $75 per adult | No |
| Admin / move-in fee | $100 to $400 | No |
As a rough planning figure, many renters find they need three to four times the monthly rent available in cash to move in once first month, a deposit, and fees are added together.
Example Problems
Example 1: A standard move-in with first month, deposit, and last month.
The rent is $1,800 per month. The landlord collects the first month, one month’s security deposit, and the last month’s rent up front, with no broker or pet fees. The move-in cost is 1,800 + 1,800 + 1,800 = $5,400, of which $1,800 (the deposit) is refundable.
Example 2: A mid-month move-in with a broker fee.
The rent is $2,400 and you move in with 12 days left in a 30-day month. The prorated first month is 2,400 / 30 * 12 = $960. Add a one-month security deposit of $2,400 and a broker fee equal to one month ($2,400). The total due at move-in is 960 + 2,400 + 2,400 = $5,760.
Frequently Asked Questions
How much money do I need to move into an apartment?
Plan on roughly three to four months of rent in cash. A very common structure is first month, last month, and a one-month security deposit, which alone equals three months of rent before any broker fee, pet deposit, or application fees are added. Building a small buffer on top covers movers and utility set-up.
Is the security deposit part of my move-in cost?
Yes, you pay it up front, so it is part of the cash you need on move-in day. The difference is that a security deposit is usually refundable when you leave the unit clean and undamaged, while fees such as application, admin, and broker charges are not. This calculator shows the refundable and non-refundable portions separately.
Can a landlord charge first month, last month, and a deposit all at once?
In many places, yes, though several states cap the total up-front amount, often at the equivalent of two to three months of rent. Limits on security deposits and whether last month’s rent counts toward that cap vary by state and city, so check your local rules before signing.
