What is the net after tax income of a self employed individual. S-Corporation, 150,000 gross income (after business expenses but before payroll, payroll taxes, employer side FICA taxes). Assume 75,000 owner payroll and reminder of funds distributed as an owner distribution. MFJ, no child tax credits, state of Texas.

Recalculate scenario with a 401k contribution of 20% of business gross income ($30,000). Max out employee contribution and remainder issued as a company profit share 401k contribution, if within limits. Average annual household living expense is 6,000 to 8,500 per month. Let's assume 7,300 monthly as a buffer for unexpended one time expenses (87,600). • Invest the remaining funds in a brokerage account.
• Date of birth is 1/1/1978.
• Planned retirement age 67.
• Company income and living expenses grow at a rate equal to inflation.
• 401k contritions continue annually at a rate of 20% of company gross income.
• Estimate average annual investment returns to yield 7% for 401k and brokerage

Create a table with a row every 5 years starting at 47 ending at 67. Columns, 401k balance, brokerage balance, annual gross business income, annual living expenses. Display results in nominal dollars
--
Expand table to age 87. Business income stops at the end of age 66. What is the estimated social security distribution (nominal dollars), if starting at full retirement age of 67? Based on 35 years of SS credits adjusted annually before and after 2026, based on 2026 payroll of 75,000.
--
Combine columns "Annual Gross Business Income" and "Social Security Benefits" Update column label to "Business Income / SS benefit."
--
Start 401k and brokerage distributions at age 67. Withdraw enough funds per year to cover estimated living expenses. Withdraw a similar percentage of account balance from each account. For example, if 5% from 401k, then approximately 5% from brokerage. Calculate withdrawals based on enough funds to cover income tax from 401k, social social security and capital gains tax from brokerage. Add columns, "401k withdrawal," "brokerage withdrawal" these amounts are the pretax value. All in nominal dollars.
--
Adjust withdrawals from 401k and brokerage to yield living expense less gross social security benefit.
--
update table to display every year from 47 to 87. Add column title every 10th row from readability.
--
Math check... From age 57 to 58, 401k balance increase from 413,071 to 462,181, this is with a 71,954 withdrawal and 7%? rate of return?

Please revert discussion to the table results from the request "Adjust withdrawals from 401k and brokerage to yield living expense less gross social security benefit." Apply the same math check analysis on that previous table.

Starting at withdrawal year, calculate next years rate of return based on ((previous year balance - withdrawal) * 1.07)). Example, age 68 401k balance is 1,674,743 minus 59,347 = 1,615,396. 1,615,396 * 1.07 = 1,728,473.72
