How it works
1031 exchange calculator — general takes your inputs and produces tax if selling traditionally, tax deferred with 1031, additional investment power, future tax liability. Calculate tax deferral benefits of a 1031 like-kind exchange and compare with selling traditionally. You provide 5 inputs: Sale Price of Relinquished (currency, in dollars) (default: 400000 dollars); Original Cost Basis (currency, in dollars) (default: 200000 dollars); Accumulated Depreciation (currency, in dollars) (default: 50000 dollars); Replacement Property Price (currency, in dollars) (default: 500000 dollars); Capital Gains Tax Rate % (percent, in percent) (default: 20 percent). The calculator returns 4 outputs: Tax if Selling Traditionally (a secondary output); Tax Deferred with 1031 (a secondary output); Additional Investment Power (a secondary output); Future Tax Liability (the primary result). Business tax and finance calculations combine multiple moving parts — revenue, expenses, depreciation, tax brackets, and timing — in ways that make back-of-envelope estimates unreliable. This calculator handles the interaction of those variables precisely, so your business decisions rest on real arithmetic. With the default values, future tax liability is computed from the interaction of every input field — change any one of them and the result updates immediately, so you can stress-test different scenarios without re-entering the whole form. Adjust the inputs to match your real financial situation. The defaults are realistic starting points, but every person's circumstances differ — your actual income, expenses, rates, and timelines will produce a different answer. Use the tool iteratively: start with the defaults, then change one variable at a time to see which factor has the largest impact on your outcome.Tips
- Start with the default values to see a baseline result, then change one input at a time to understand which factor matters most for your outcome.
- Replace every default with your actual number — estimates and rules of thumb produce estimates, not answers. Pull your real figures from pay stubs, statements, or account dashboards.
- Run the numbers quarterly, not annually. Tax brackets, revenue, and expenses shift throughout the year, and adjusting early is far cheaper than correcting at year-end.
Frequently asked questions
How long do I have to complete a 1031 exchange?
You have 45 days to identify replacement properties and 180 days to close on the new property. Missing these deadlines disqualifies the exchange.
What does the 1031 exchange calculator — general calculate?
It takes sale price of relinquished, original cost basis, accumulated depreciation, replacement property price, capital gains tax rate % as inputs and computes tax if selling traditionally, tax deferred with 1031, additional investment power, future tax liability. The primary output is future tax liability. Calculate tax deferral benefits of a 1031 like-kind exchange and compare with selling traditionally.
How accurate are the calculator results?
The math is exact — the same formulas a financial professional would use by hand. The precision of the output depends entirely on how realistic your inputs are. Use your actual numbers rather than estimates when possible. The defaults are reasonable starting points, but your real income, rates, and timeline will produce a different result.
