Frequently Asked Questions
Why do the examples use estimated rates?
Actual rates depend on location and circumstances, so the examples use illustrative rates to demonstrate the calculation method.
What happens if monthly expenses exceed revenue?
The calculator sets estimated taxable profit to zero, so it does not create a negative tax reserve.
Should I use the same reserve every month?
A consistent transfer can be practical when income is steady, but updating inputs as revenue and expenses change gives a more current estimate.
How is the annual amount calculated in these examples?
It is the recommended monthly reserve multiplied by twelve.
