The short answer

Last updated: July 2026

A rental listing promotion breaks even when the cost equals the rent saved by filling a unit sooner. Divide the promotion or incentive cost by daily rent (monthly rent × 12 ÷ 365) to estimate the vacancy days it would need to avoid. This tool does not predict lease-up speed.

Put a price on a faster lease-up.

Compare the fixed cost of a listing promotion or leasing incentive with the rent lost during vacancy, using the rent and days you enter.

Vacancy days needed to break even

6.1 days

$380 cost ÷ $62 daily rent. 14 vacant days would mean about $1,255 in lost rent plus the cost.

Estimate only. It does not predict whether a promotion will lease a unit faster or account for screening quality, concessions, carrying costs, or fair-housing obligations.

How it works

How this tool works.

A promotion can be cheaper than leaving a unit empty, but only if it meaningfully shortens the vacancy. The useful question is how many vacant days the expense has to prevent.

This calculator translates a fixed promotion or incentive cost into that break-even day count using your own rent.

Enter the monthly rent you would collect.

Enter the promotion or incentive cost.

The tool converts monthly rent to daily rent.

It divides the cost by daily rent to show the vacant days the expense would need to avoid.

Make the result useful

Ask how many vacant days the spend must avoid

A listing promotion or incentive has a clear rent-only break-even: its cost divided by daily rent. That makes the lease-up assumption explicit.

It cannot prove that a promotion will work; use it to bound a decision, not to promise a result.

The assumptions that move this result

Monthly rent

Expected collected rent after lease-up.

Promotion cost

One fixed listing or incentive cost.

Vacancy days

Scenario days without rent.

Worked scenario

At $1,900/month, daily rent is about $62.47. A $380 promotion needs to avoid about 6.1 vacant days to offset itself on rent alone.

Does this predict faster leasing?

No. It only calculates the threshold.

Does it include carrying costs?

No. Add them separately if relevant.

Answers

Questions, answered plainly.

Will a promotion fill my unit faster?

This tool cannot say. Listing quality, pricing, demand, screening, and timing determine lease-up speed.

Does it include mortgage or utilities?

No. It isolates lost rent and the stated cost. Carrying costs can make vacancy more expensive.
