How to use the Rent Reduction vs Vacancy Calculator
- Enter the rent the unit is advertised at now and the lower rent you are weighing.
- Enter the length of the lease the new tenant would sign.
- Add any costs you pay only because the unit is empty, and the days it has been empty so far.
Two ways to lose rent
rent given up = (asking rent − lower rent) × lease monthscost of a vacant day = (asking rent + costs only while empty) × 12 ÷ 365break-even days = rent given up ÷ cost of a vacant dayA vacant unit loses money in one of two ways. Holding the asking rent risks more empty days. Lowering it fills the unit sooner, perhaps, but collects less every month for the whole lease. The break-even puts both in days: the lower price has to shorten the vacancy by at least that many days to make up for what it gives up.
Reading the result against the calendar
The number that matters is not the break-even alone but how it compares with what you see in the market: showings, applications, how long similar units have been listed. A cut that has to save three weeks is a different decision in a slow winter market than in a busy summer one. The page supplies the arithmetic; the judgement about how fast each price will let stays yours.
The vacancy cost so far is there for context. Rent already lost is lost under either choice, so it does not change the break-even; it only shows what the empty weeks have cost.
What is outside it
This page prices a single vacant unit for one lease. It does not model occupancy across a building (the break-even occupancy calculator does), a partial first month (the prorated rent calculator), turnover costs, or the effect of the new rent on renewals and on nearby units. Rent-setting rules and any limits on increases vary by place.
With your numbers
- Rent given up = ($2,000.00 − $1,900.00) × 12 months = $1,200.00
- Cost of a vacant day = $2,000.00 × 12 ÷ 365 = $65.75
- Break-even = $1,200.00 ÷ $65.75 = 18.3 days
Quick reference
Arithmetic on your two prices. It cannot tell how much sooner a lower rent will actually fill the unit.
| Example | Days sooner the lower rent has to fill the unit |
|---|---|
| 2,000 to 1,900 on a 12-month lease | 18.3 |
| 3,400 to 3,100, with 150 a month of vacancy costs | 30.8 |
| 1,450 to 1,395 on an 18-month lease | 20.8 |
| 50 off 1,200 on a 6-month lease | 7.6 |
| 1,800 to 1,700 after 30 empty days | 20.3 |
| 950 to 900 on a two-year lease | 38.4 |
Common questions about the Rent Reduction vs Vacancy Calculator
- What does the break-even number of days mean?
- It is how much sooner the lower rent has to find a tenant for the two choices to come out even over the lease. If you expect the lower price to fill the unit more days sooner than that, the lower price brings in more; if fewer, holding the price does. The page cannot tell you how quickly either price will let.
- Why are the mortgage, tax and insurance left out of the daily cost?
- Because you pay them whether the unit is let or not, so they are the same under both choices. Counting them as a cost of vacancy makes every empty day look dearer than it is and pushes the answer towards cutting the rent. Only costs that exist because the unit is empty belong in that field: utilities you now carry, lawn care, or listing fees.
- Why 12 ÷ 365 rather than dividing by 30?
- A year of rent spread over 365 days gives the average daily rent across long and short months. Dividing by 30 overstates it slightly in a 31-day month and understates it in February.
- Does it matter that the tenant may renew?
- Yes, and the page leaves it out on purpose. If the lower rent carries into renewals, it gives up more than one lease’s worth. To see that, enter a longer lease length covering the time you expect the tenant to stay.
- Is a move-in concession the same as a lower rent?
- Not quite. A concession, such as a free first month, gives up a fixed sum once rather than a monthly amount. Enter it as a lease of one month with the reduction equal to the concession, and the break-even days are the concession divided by the cost of a vacant day.
