Should My Spouse Work?
This calculator is designed to help you see the financial impact of adding, or removing, a spouse's income to your household. As with any decision of this type, there are many factors to consider, but knowing your finances is a good place to start.
Definitions
Pay period
This is how often you are paid. Your selections are: Weekly (52 paychecks per year), Every other week (26 paychecks per year), Twice a month (24 paychecks per year), Monthly (12 paychecks per year), and Annually (one paycheck per year).
Gross pay
This is your gross pay, before any deductions, for the pay period. Please enter a dollar amount from $1 to $1,000,000.
Number of allowances
When your Federal income tax withholdings are calculated, you are allowed to claim allowances to reduce the amount of the Federal income tax withholding. In 2004, each allowance you claim is equal to $3,100 of income that you expect to have in deductions when you file your annual tax return. The number of allowances you should claim depends largely on the number of dependents you have and your itemized deductions. This calculator allows from 0 to 99 allowances. Please note that this calculator assumes that you have a filing status of "Married".
401(k)/403(b) plan withholding
This is the percent of your gross income you put into a taxable deferred retirement account such as a 401(k) or 403(b). While increasing your retirement account savings does lower your take home pay, it also lowers your Federal income tax withholdings. The impact on your paycheck might be less than you think. While your plan may not have a deferral percentage limit, this calculator limits deferrals to 80 percent to account for FICA (Social Security and Medicare) taxes. Please note that your 401(k) or 403(b) plan contributions may be limited to less than 80 percent of your income. Check with your plan administrator for details. For 2004, the maximum contribution to a 401(k) or 403(b) is $13,000 per year for individuals under 50 and $16,000 for individuals over 50.
State and Local Taxes
This is the percentage that will be deducted for state and local taxes. We take your gross pay, minus $3,100 per allowance, times this percentage to calculate your estimated state and local taxes. Please note, this calculator can only estimate your state and local withholdings.
FICA OASDI
FICA Old Age Survivors and Disability Insurance. FICA OASDI is calculated as your gross earnings times 6.2 percent. Please note that this calculator does not make any assumptions as to the total FICA OASDI paid for the current year. For 2004, incomes over $87,900 that have already had the maximum FICA OASDI amount of $5449.80 withheld will not have additional FICA OASDI withholdings.
FICA Medicare
FICA Medicare is calculated as the gross earnings times 1.45 percent. Unlike FICA OASDI there is no annual limit to FICA Medicare deductions.
Federal tax withholding calculations
Federal income tax withholdings were calculated by:
1. Multiplying taxable gross wages by the number of pay periods per year to compute your annual wage.
2. Subtracting the value of allowances allowed (for 2004 this is $3,100 multiplied by withholding allowances claimed).
3. Determining your annual tax by using the tables below.
4. Dividing the amount of tax by the number of pay periods per year to arrive at the amount of federal withholding tax to be deducted per pay period.
Additional expenses when spouse works
This are any additional expenses that you will need to pay when your spouse works. All of the expenses should be entered as the amount per pay period.
