Rental Depreciation Calculator
Depreciation is often the biggest tax shield a rental delivers — turning positive cash flow into a paper loss for years. This calculator sets basis, applies the 27.5 or 39-year recovery period, and sizes the first-year mid-month amount.

How the math works
Residential rental property depreciates over 27.5 years; commercial over 39. The IRS uses the mid-month convention: the first year gets depreciation starting mid-month of placement.
Only the building is depreciable — land is not. A typical split puts 20–30% of purchase price on land. Improvements (new roof, HVAC, etc.) add to basis over time. Sale triggers recapture tax up to 25% on the depreciation taken.

How this calculator works
What this page estimates
This Rental Depreciation Calculator is built to give a quick, browser-based estimate for rental depreciation. Depreciation is often the biggest tax shield a rental delivers — turning positive cash flow into a paper loss for years. This calculator sets basis, applies the 27.5 or 39-year recovery period, and sizes the first-year mid-month amount. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.
Calculation approach
The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.
Example workflow
For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.
Practical checks
- Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
- Run a low, base, and high case when the inputs are estimates.
- Check the related calculators below when the next decision depends on a different assumption.
How to interpret the rental depreciation result
Best use
Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.
Cross-check
Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.
Watch for
Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.
This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.
Before relying on this rental depreciation estimate
Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.
Confirm source numbers
Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.
Separate cash flow from total cost
A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.
Run conservative cases
Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.
Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.
How to Use
- Enter purchase price and the land share of that price. Typical: 20–30% for land.
- Enter any capital improvements added to basis (new roof, kitchen remodel, etc.).
- Pick residential (27.5 years) or commercial (39 years).
- Enter the month the property was placed in service for the mid-month convention.
- Enter marginal tax rate to size the tax shield.
Frequently Asked Questions
Why isn't land depreciable?
Depreciation is a recovery of cost for a wasting asset — land doesn't wear out. The IRS splits purchase price between building (depreciable) and land (not). Most investors use the tax assessor's ratio as a starting point.
What's the mid-month convention?
First-year depreciation is prorated assuming the property was placed in service in the middle of the stated month. A March placement gets depreciation for 9.5 months (9.5/12 of the annual amount).
What happens when I sell?
Depreciation recapture: the depreciation taken is taxed as ordinary income up to 25% (Section 1250 unrecaptured gain). Run our Depreciation Recapture Tax Calculator to size this at sale.
Can I speed this up?
Yes — cost segregation breaks out 5-year and 15-year components (flooring, cabinets, landscaping) and bonus depreciation can accelerate those. Expect a 15–30% first-year deduction boost on a typical residential rental.
