Passive Activity Loss Calculator

What this page estimates

This Passive Activity Loss Calculator is built to give a quick, browser-based estimate for passive activity loss. PAL rules restrict rental loss deductions — suspended and carried forward unless you qualify for the $25K active participation allowance. This calculator applies the phaseout and determines current-year deductible loss. Real estate professional status (REPS) unlocks full current-year deduction of rental losses. To qualify: spend more than 750 hours during the year in real property trades/businesses AND more than half of personal services in real estate. Document hours contemporaneously. Each rental property is a separate activity unless you file an election to group them — grouping is often advantageous but must be done explicitly on the return. 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.
