Ask a landlord what turnover costs and most answer with the vacancy: a few weeks of empty rent. That is real money, but it is usually the smaller half of the number. Add the make-ready work, the re-leasing costs, and the time spent running the whole process, and turnover tends to cost more than it looks like from the vacancy alone, which is exactly why it is worth calculating properly before you decide whether an increase, a concession, or a hard line is the cheaper move.
1. The four categories that make up the real number
Turnover cost is not one line item, it is four, and landlords who only track the first one tend to underestimate the total by a wide margin:
| Category | What it covers |
|---|---|
| Vacancy | Lost rent for every week the unit sits empty between tenants, plus utilities you cover during that gap. |
| Make-ready | Cleaning, paint touch-up, carpet or flooring repair, and any deferred maintenance you address between tenants. |
| Re-leasing | Listing and advertising costs, time spent on showings, screening (background and credit checks), and a leasing agent's fee if you use one, often close to a month's rent in many markets when you do. |
| Administrative time | Your own hours, or your property manager's billed time, coordinating the whole process: fielding inquiries, scheduling showings, running paperwork. |
2. A worked example
Every assumption below is stated so you can swap in your own numbers; this is one illustrative scenario, not a benchmark to expect.
Worked example: a $2,200/mo unit, 5-week vacancy
Illustrative only. If you use a leasing agent, add roughly one month's rent in fees on top in many markets. Your own vacancy length, market, and make-ready scope will move every line.
Against that number, a landlord weighing a renewal decision has a clean comparison: is the gain from pushing rent to market, or the savings from refusing a concession, larger than roughly $3,830 times the odds this decision is the one that causes the tenant to leave? Framed that way, a modest concession to retain a good tenant is often the cheaper option, not the generous one.
3. Calculate your own number
Use your own figures in place of the illustrative ones above. The formula is the same regardless of market:
Turnover cost ≈ (vacancy weeks ÷ 4.33 × monthly rent) + make-ready costs + re-leasing costs + administrative time (valued at your hourly rate, or your manager's billed hours).
| Line item | Your number |
|---|---|
| Typical vacancy length (weeks) | _____ |
| Monthly rent for this unit | _____ |
| Make-ready cost, last turnover | _____ |
| Advertising + screening cost | _____ |
| Leasing agent fee, if used | _____ |
| Your hours × your hourly value | _____ |
| Total turnover cost | _____ |
Do this once with your real numbers from your last turnover and you have a figure worth using in every renewal decision going forward, instead of a generic estimate that may not match your market or your unit.
4. Reducing tenant turnover, once you know what it costs you
The number above is what makes retention efforts easy to justify: most of them cost far less than a single turnover.
- Price renewals defensibly, not maximally. A smaller, well-justified increase that a tenant accepts without friction is usually cheaper than a larger one that triggers a move-out. See our rent increase calculator guide for the method.
- Send renewal notices with real lead time. A rushed, last-minute renewal reads as disorganized and gives a tenant less runway to say yes before they have already started looking elsewhere. Our renewal timing calendar lays out the full sequence.
- Stay responsive on maintenance. Slow repairs are one of the most common reasons a tenant who would otherwise renew starts looking instead. Fast, reasonable responses cost far less than the turnover they prevent.
- Check in before the renewal decision, not at it. A short conversation weeks ahead of the notice gives you a real read on whether the tenant is likely to stay, instead of finding out only when the letter goes unanswered.
5. Why the number is not the same for every unit
The worksheet above gives you one number per unit, and it is worth running separately for each rather than assuming a portfolio-wide average is close enough. A few patterns worth accounting for:
- Unit type changes both vacancy length and make-ready scope. A single-family house often takes longer to re-lease than an apartment in a larger building, simply because the pool of interested renters searching at any given time is smaller, and it can also carry more make-ready work (yard, larger floor area, more systems to check).
- Furnished or amenity-heavy units add re-leasing time. More features to photograph, describe, and show usually means more showings before a tenant commits, which stretches the vacancy window even when demand is otherwise strong.
- A unit's history matters as much as its type. If a specific unit has turned over faster or slower than the rest of your portfolio in the past, that pattern is more predictive of its next turnover cost than a portfolio-wide average would be.
Recalculating the worksheet after every turnover, rather than once and forgetting it, is what turns this from a one-time estimate into a running number you can actually trust when a renewal decision comes up. It also surfaces which units are consistently expensive to turn over, which is often a stronger signal for where to invest in retention than rent level alone.
Put it together
Turnover costs more than the empty weeks alone. Add make-ready, re-leasing, and your own time, and the real number is usually large enough to change the renewal decision it gets compared against. Calculate yours once with real figures, and use it every time you weigh an increase, a concession, or a hard line against the cost of losing the tenant.

Frequently asked questions
What actually counts as tenant turnover cost?
Four categories, at minimum: lost rent during the vacancy, make-ready work (cleaning, repairs, paint), re-leasing costs (advertising, showings, screening, any leasing-agent fee), and the administrative time it takes you or your property manager to run the whole process. Most landlords track the first two and undercount the last two.
How do I calculate my own tenant turnover cost?
Add your actual vacancy length in weeks (converted to a share of a month) times your monthly rent, plus your real make-ready spend, plus advertising and screening costs, plus any leasing fee. Use your own numbers, not a generic benchmark; the worksheet in this guide walks through it line by line.
Is a $200-a-month rent increase worth the turnover risk?
Depends on your actual turnover cost against your actual odds of losing the tenant over that increase. As a rule of thumb, if your calculated turnover cost is close to or larger than one year of the increase's added income, the increase needs a very high odds of retention to be worth it. Run your own numbers rather than assuming the arithmetic works in your favor.
What is the single best way to reduce tenant turnover?
There is no one lever, but the highest-leverage habit is treating renewal as a proactive process instead of a reactive one: checking in on the tenant relationship well before lease end, pricing the renewal defensibly instead of maximally, and sending notices with real lead time rather than a scramble.
Does keeping rent below market always pay for itself?
Not automatically, and not forever. A below-market renewal is a bet that the retained tenant's stability is worth more than the market gap, which is usually true for one or two renewal cycles with a good tenant, but a gap that grows every year eventually outweighs the turnover risk it was meant to avoid. Revisit the comparison at every renewal, not just the first one.
