Vacancy costs operators money every day. Here is how to count it.
An empty apartment is not a neutral state. It is a daily bill. Here is the simple math to price every day a unit sits.
A vacant apartment costs its monthly rent x 12 / 365 for every day it sits empty. At the NYC median asking rent of $4,150, that is about $136 a day.
- →Manhattan median: about $164 a day. Brooklyn: about $130. Queens: about $112.
- →30 empty days on a median NYC unit is about $4,093 in lost rent.
- →That money never comes back. You cannot charge it to the next tenant.
Most owners know their rent roll to the dollar.
Very few know what an empty unit costs them per day.
That number is the most important one in leasing. Every decision you make about price, photos, showings and who you rent to is really a decision about days.
So let’s count it.
How do you calculate the cost of a vacant apartment?
The formula is simple.
Monthly rent x 12 / 365 = what you lose every day the unit is empty.
Take the median NYC asking rent from public market data for September 2026: $4,150.
$4,150 x 12 = $49,800 a year.
$49,800 / 365 = about $136 a day.
That is $136 gone every single morning the keys sit in a drawer.
Here is the same math across the boroughs:
- Manhattan ($4,995 median): about $164 a day.
- Brooklyn ($3,945 median): about $130 a day.
- Queens ($3,400 median): about $112 a day.
What does a week, a month or two months of vacancy cost?
Here is the daily number multiplied out. Same formula, rounded to the dollar.
| Days vacant | NYC ($4,150) | Manhattan ($4,995) | Brooklyn ($3,945) | Queens ($3,400) |
|---|---|---|---|---|
| 7 days | $955 | $1,150 | $908 | $782 |
| 14 days | $1,910 | $2,299 | $1,816 | $1,565 |
| 30 days | $4,093 | $4,927 | $3,891 | $3,353 |
| 60 days | $8,186 | $9,853 | $7,782 | $6,707 |
Look at the 60 day row.
Two slow months on a median Manhattan unit is almost $10,000.
That is more than 2 months of the rent you were holding out for.
And it does not come back.
You cannot bill the next tenant for the days nobody lived there.
Why the daily number changes how you price
Here is how I see it.
Most owners think about price in monthly terms. “I don’t want to drop $100 a month.”
Fine. But $100 a month is $1,200 a year.
At $136 a day, that is less than 9 empty days on a median NYC unit.
So the real question is not “should I cut the price?”
It is “will this price cost me more than 9 days?”
The market is already answering that. In September 2026, 16.0% of NYC rental listings had a price cut and 17.6% offered at least 1 month free. Owners are paying for days one way or another.
A free month on a $4,150 apartment is $4,150. That is the same as about 30 vacant days. If the concession gets the unit signed in a week instead of a month, it paid for itself. If it doesn’t, you paid twice.
Where the days actually go
When I break down a slow lease-up, the days almost never come from one big problem. They leak out in small pieces.
- Turnover. Paint, cleaning, repairs. Every day between move-out and “ready to show” counts.
- Getting seen. Bad photos, no video, a listing nobody stops scrolling for.
- Showings to the wrong people. Tours with renters who were never going to qualify.
- Applications that fall apart. Documents that don’t add up, an applicant who goes quiet, starting over.
- Lease signing. Back and forth on terms, waiting on a guarantor, waiting on a deposit.
Each one is a few days. Together they are a month.
Count them separately and you will know exactly where your money is going.
How fast can a unit actually lease?
On Nessoo, the median unit leases in 4.8 days.
At the NYC median rent, 4.8 days is about $655 of vacancy.
The reason is not magic. Renters on Nessoo verify their income and identity once, upfront. They get matched directly to units that fit their budget. So the showings are with people who can actually sign, and the application step that usually eats days is already done.
What I would do this week
- Write your daily number on every listing file. Rent x 12 / 365. Make the whole team look at it.
- Track days, not just rent. Log move-out date, ready date, first showing, application and lease signed. Find the gap.
- Price against days. Before you hold out for an extra $100 a month, ask whether it is worth 9 days.
- Treat concessions as math, not panic. A free month equals about 30 vacant days. Only offer it if it saves more than that.
- Stop showing to people who cannot sign. Every unqualified tour is a day you will not get back.
Vacancy is the one cost in this business you can see coming and still ignore.
Don’t ignore it. Count it.
“An empty apartment is not waiting. It is losing.”
Frequently asked questions
How do you calculate the daily cost of a vacant apartment?
Take the monthly rent, multiply by 12, and divide by 365. A $4,150 apartment loses about $136 a day in rent while it sits empty.
How much does a month of vacancy cost in NYC?
At the citywide median asking rent of $4,150, 30 empty days is about $4,093 in lost rent. In Manhattan, at a $4,995 median, it is about $4,927.

Often, yes. Compare the yearly cost of the cut with the daily cost of waiting. A $100 a month cut costs $1,200 over a year, which is less than 9 empty days on a median NYC unit.
