Calculation Method
The calculator uses the following formula to determine your taxable income:
Taxable Income = Total Income - Standard Deduction
Once you have your taxable income, the calculator applies the appropriate tax brackets to calculate your total tax liability.
For example, if you earn $50,000 as a single filer:
- Subtract the standard deduction ($6,300) from your total income: $50,000 - $6,300 = $43,700
- Calculate the tax owed in each bracket:
- $9,075 at 10% = $907.50
- $27,825 at 15% = $4,173.75
- $9,800 at 25% = $2,450.00
- Add up the taxes: $907.50 + $4,173.75 + $2,450.00 = $7,531.25
Worked Example
Let's walk through a complete example to illustrate how the calculator works.
Scenario
You are a single filer with a total income of $60,000 for 2015.
Step 1: Apply the Standard Deduction
The standard deduction for a single filer in 2015 is $6,300.
Taxable Income = $60,000 - $6,300 = $53,700
Step 2: Calculate Tax in Each Bracket
Now, we'll calculate the tax owed in each bracket:
| Bracket | Taxable Income | Tax Rate | Tax Owed |
|---|---|---|---|
| 10% | $9,075 | 10% | $907.50 |
| 15% | $27,825 | 15% | $4,173.75 |
| 25% | $16,800 | 25% | $4,200.00 |
Step 3: Sum the Taxes
Add up the taxes from each bracket:
Total Tax = $907.50 + $4,173.75 + $4,200.00 = $9,281.25
Step 4: Calculate Effective Tax Rate
The effective tax rate is calculated by dividing the total tax by your total income:
Effective Tax Rate = ($9,281.25 / $60,000) × 100 = 15.47%
Final Results
Based on this calculation, your estimated 2015 federal income tax would be $9,281.25, with an effective tax rate of 15.47%.
