Frequently Asked Questions
How accurate are the results?
The Home Office Tax Deduction applies a standard formula to your inputs — accuracy depends on how precisely you measure those inputs. For planning and estimation, results are reliable. For high-stakes or professional decisions, cross-check the output with a domain expert or primary source.
What inputs have the biggest effect on the result?
In most financial calculations, the variables with the highest sensitivity are the rate (interest, return, or tax) and time. Try adjusting each by 10-20% to see which one moves the output most — that's where your energy in improving the input estimate is best spent.
