Dertermine the profit margin?

Income Tax Expenses $139,200
Sales $1,348,000
Selling Expenses $383,100
Interest Expense $5,800
General & Admin. exp. $369,990
Earnings per share $2.97
Stockholders Equity $549,000

Add up all expenses: Income tax, Selling, Interest, G&A

Total Expenses = $ 898,090

Profit = Sales - Expenses = $ 449,910

Divide Profit by Sales to get Profit Margin = 33.37%

All expenses prior to taxes are removed from Sales = $589,110.

Also 34% blended rate for fed = $139200/.34 + 155K avg deductions = so it should be around... $564411.76

That's my guess. Could be wrong though can't remember exact school book terminology

Its around $500,000 USD after taxes and expenses. Good hit that one!

Profit margin (Bottom line) is net profits divided by sales. (these are the same)
Net Profit: total rexpenses minus total revenue.
(139200+383100+5800+369990) = 898090
Total Sales = 1348000
1348000-898090 = 449910
Profit Margin is (449910/1348000) 33.376%
This looks like good. I would compare this to other companies within the sector prior to buying though. But a 30+% PM is nice. What is really impressive is this company has a Return on Equity (ROE) of 81.95%. That is nice.
ROE = Net Income (449910/549000) divided by Shareholder Equity
