And there is nothing to worry here actually, for even if you have set your hard disk to turn off after say 5 mins, if there is some background maintenance task being carried out, it will not shut down â but instead the system will reset the hard diskâs idle timer.
The Average Tax Rate Definition. The average tax rate in the United States varies depending on the amount of income to which it's applied. An average tax rate as it applies to income tax may be defined as the percentage of income owed as taxes or, as Fair Tax defines the term, as the ratio of taxes paid to taxable income. In mathematical terms, divide the total tax liability by total taxable income to get the average tax rate.
Average tax rates measure tax burden, while marginal tax rates measure the impact of taxes on incentives to earn, save, invest, or spend. The average tax rate is the total amount of tax divided by total income. For example, if a household has a total income of $100,000 and pays taxes of $15,000, the householdâs average tax rate is 15 percent. The marginal tax rate is the incremental tax paid on incremental income.
