Airbnb Depreciation Calculator: How Much Can You Actually Deduct?

Depreciation is usually the single biggest deduction an Airbnb host can claim — often five figures a year — and it costs you nothing out of pocket. Yet many first-time hosts skip it entirely, or guess at the numbers. Use the calculator below to estimate your depreciable basis, your annual deduction on both the 27.5-year and 39-year schedules, and your first-year amount under the mid-month convention.

This article is educational content, not tax advice. Depreciation rules have real edge cases — especially for short-term rentals — so confirm your specific situation with a CPA before filing.

The rest of this guide walks through every number the calculator just produced — where the basis comes from, why there are two schedules, and what the mid-month convention does to year one.

What Depreciation Is (and Why Most Hosts Underuse It)

The IRS treats your rental building as an asset that wears out over time, and lets you deduct a slice of its cost every year you rent it out. That's depreciation. Two things make it unusual among deductions:

• It's non-cash. You don't spend anything to claim it. Your property can be appreciating in market value while you deduct thousands per year for its "wear."
• It applies to the building, never the land. Land doesn't wear out, so you must strip its value out of your purchase price before you calculate anything.

Here's the worked example we'll use for the rest of this guide. You buy a property for $400,000. Your county's property tax assessment allocates $80,000 to the land (20%). Your depreciable basis is:

On the standard 27.5-year residential schedule, that's $320,000 ÷ 27.5 = $11,636 per year, every year, for over two decades. At a 24% marginal rate, that single line saves roughly $2,793 a year in tax. Depreciation goes on Form 4562 in the year you place the property in service, then flows to line 18 of Schedule E. IRS Publication 527 (Residential Rental Property) is the primary reference.

27.5 or 39 Years? The Short-Term Rental Question

This is where Airbnb hosts hit genuine ambiguity, so let's handle it honestly rather than pretending there's one clean answer.

Residential rental property depreciates over 27.5 years. That's the schedule most landlords use, and it's what Publication 527 describes. But "residential" has a meaning: people living in the property as a dwelling. Many CPAs take the position that a short-term rental where the average guest stay is 7 days or less is transient use — functionally closer to a hotel than a home — and depreciate the building as nonresidential property over 39 years instead.

On our $320,000 basis, the difference is real money:

That's about $3,431 per year of deduction riding on the classification. And here's the honest part: this is unsettled terrain in practice. Reasonable, competent tax professionals disagree about when the 39-year treatment applies to a given STR, and the answer can turn on your average stay length, whether the property is a dwelling unit, and how your activity is characterized overall. Do not take either schedule from a blog post — including this one — as universally correct.

Year One: The Mid-Month Convention

You don't get a full year of depreciation in the year you start renting. Real property uses the mid-month convention: whatever month you place the property in service, the IRS treats it as placed in service at the middle of that month. The first-year fraction is:

Worked example: your listing goes live and is available for booking in June (month 6). You get credit for 6.5 months of the year — half of June plus July through December. On the 27.5-year schedule:

On the 39-year schedule the same June start gives you $8,205 × 6.5 ÷ 12 = $4,444. Note that "placed in service" means ready and available to rent — the day your listing could take a booking — not the day your first guest checks in, and not the day you closed. From year two onward you claim the full annual amount.

What Adds to Basis vs. What You Deduct This Year

Your depreciable basis isn't just the purchase price minus land. Some costs get added to it, and knowing the difference between an improvement (depreciated) and a repair (deducted now) matters:

• Adds to basis: closing costs like title fees, legal fees, recording fees, transfer taxes, and surveys — plus improvements that add value or extend the property's life: a new roof, an addition, a full kitchen renovation, a new HVAC system. If you paid $6,000 in qualifying closing costs on our example property, your basis becomes $326,000 and the annual numbers scale up accordingly.
• Current-year expense: repairs that keep the property in operating condition — fixing a faucet, patching drywall, servicing the furnace. These go straight on Schedule E in the year you pay them, no depreciation required.

Furniture and appliances are their own category — typically depreciated over 5-7 years rather than folded into the building. For the full repairs-vs-improvements breakdown and 50+ deductible categories, see our guide to every Airbnb tax deduction you can claim in 2026.

"Allowed or Allowable": Why Skipping Depreciation Is Pure Loss

Some hosts deliberately skip depreciation because they've heard about recapture tax at sale and figure they'll avoid it. Here's the problem: depreciation is effectively not optional. When you sell, the IRS reduces your cost basis by the depreciation that was allowed or allowable — whether or not you actually claimed it. Skip the deduction and you get the worst of both worlds: no tax savings along the way, and the same reduced basis (and bigger taxable gain) at sale.

So what is recapture? When you sell, the portion of your gain attributable to depreciation you took on the building — called unrecaptured §1250 gain — is taxed at up to 25%, rather than at the lower long-term capital gains rates. If you claimed $11,636 a year for ten years, that's roughly $116,364 of gain taxed at up to 25% when you sell.

That sounds scary until you look at the full trade honestly:

• Deferral has value. A dollar of tax saved this year is worth more than a dollar of tax paid at sale years from now.
• Rate arbitrage often works in your favor. If your marginal rate is 32-37%, you're deducting at that rate and recapturing at no more than 25%. At 22-24% it's closer to a wash on rates — but deferral still wins, and remember the basis reduction happens either way.
• You may never pay it. Certain exit strategies (like a 1031 exchange, or holding until death when heirs receive a stepped-up basis) can defer or eliminate recapture entirely — talk to a CPA about what fits your plans.

Bottom line: recapture is real, but declining to claim depreciation doesn't protect you from it. Claim what you're entitled to.

Cost Segregation and Bonus Depreciation: Worth Knowing About

Everything above is straight-line depreciation — the same amount every year. Two advanced strategies can front-load deductions for STR owners:

Cost segregation is an engineering-based study that breaks your building into components — flooring, cabinetry, appliances, land improvements like fencing and driveways — and reclassifies them onto much shorter 5, 7, and 15-year schedules instead of 27.5 or 39 years. That pulls a significant chunk of your total depreciation into the first few years of ownership.

Bonus depreciation can then let you deduct a large share of those short-life components immediately in year one. We're deliberately not quoting a bonus percentage here, because the allowed percentage has been changing year to year — check the current rules with a professional rather than trusting any blog post's snapshot. Both strategies require a proper cost segregation study (typically a few thousand dollars) and genuinely benefit from professional guidance, since they interact with recapture and with how your rental activity is classified. For hosts with larger properties or high W-2 income, the math can be compelling — but it's a "hire someone" move, not a DIY one.
