Step Up Basis At Death Calculator
Heirs get basis stepped up to date-of-death value, eliminating capital gains.
Tax savings from step-up
$2,261,000
Unrealized gain
$9,500,000
New basis
$12,000,000
How the math works
Unrealized gain = FMV − basis. Tax savings = gain × capital gains rate.
$12M − $2.5M = $9.5M unrealized × 23.8% = $2.26M tax savings from step-up.
EveryCalc calculators are designed for fast, practical estimates with transparent inputs and no required account. We use plain formulas, visible assumptions, and related tools so visitors can check the result from more than one angle.
Results are informational only. For financial, tax, legal, medical, construction, or other high-impact decisions, verify the output against primary sources or a qualified professional.

How this calculator works
What this page estimates
This Step Up Basis At Death Calculator is built to give a quick, browser-based estimate for step up basis at death. Heirs get basis stepped up to date-of-death value, eliminating capital gains. 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 step up basis at death 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 step up basis at death 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.

Frequently Asked Questions
How it works?
At death, heir inherits property with basis stepped up to fair market value. Accumulated capital gains (purchase price to FMV) never taxed. Heir can sell immediately at no capital gain, or continue depreciating from higher basis.
Planning implications?
Hold appreciated property until death to eliminate lifetime capital gains. Don't 1031 into property intended to be held for estate — step-up already eliminates gains. Critical for long-term real estate families.
Exceptions?
Community property: 100% step-up for both halves at first death (CA, TX, AZ). Non-community property: 50% step-up for surviving spouse's half. IRD (income in respect of decedent): no step-up on deferred income (e.g., pension, IRAs).
