Enter Time/Space Calculations

Your Time/Space percentage represents the proportion of your home that you use for business purposes. You use this figure to determine how much of your shared business and personal expenses can be deducted as a business expense. For more information about Time/Space %, see Tom Copeland's blog The Time-Space Percentage Quiz.

The Time/Space % is determined by the following formula:

EXCLUSIVE SPACE PERCENTAGE  + (REGULAR USE AREA SPACE PERCENTAGE * TIME PERCENTAGE) = TIME/SPACE PERCENTAGE
