Formulas to Know

Percentage of completion – earned revenue and over/under billingPercent complete = costs incurred to date ÷ total estimated costs; Cumulative earnings = percent complete × contract amount; Billings − cumulative earnings = billing overage reported as a current liability (cumulative earnings − billings = current asset). Worked examples: $150,000 ÷ $500,000 = 30%; 30% × $700,000 = $210,000 earned vs $235,000 billed = $25,000 current liability. $80,000 ÷ $160,000 = 50%; 50% × $200,000 = $100,000 earned vs $115,000 billed = $15,000 current liability. Where percent of total performance is given directly: 40% × $900,000 estimated revenue = $360,000 earned.
Working capital and current ratioWorking capital = current assets − current liabilities (examples: $96,000 − $60,000 = $36,000; $140,000 − $95,000 = $45,000; $250,000 − $180,000 = $70,000). Current ratio = total current assets ÷ total current liabilities ($250,000 ÷ $180,000 = 1.39). Owners' equity = total assets − total liabilities and is NOT working capital.
Quick (acid test) ratio(Current assets − inventory) ÷ current liabilities. Examples: ($180,000 − $30,000) ÷ $100,000 = 1.50; ($320,000 − $140,000) ÷ $200,000 = 0.90.
Straight line depreciation(Initial asset cost − salvage value) ÷ useful life in years. Example: ($38,000 − $8,000) ÷ 6 = $5,000 per year.
Net income, profit margin and return on total assetsIncome − cost of goods sold = gross profit; gross profit − expenses = net income ($800,000 − $560,000 = $240,000; $240,000 − $192,000 = $48,000). Profit margin = net income ÷ revenues ($48,000 ÷ $800,000 = 6%). Return on total assets = net profit after taxes ÷ total assets ($48,000 ÷ $600,000 = 8%).
Average collection period (activity ratio)Step 1: revenue ÷ days in the business year = sales per day ($730,000 ÷ 365 = $2,000). Step 2: current receivables ÷ sales per day = average collection period ($90,000 ÷ $2,000 = 45 days).
Bid price covering direct costs plus overhead (cost-based pricing)Overhead is a percentage of revenue, not of direct cost: bid = direct costs ÷ (1 − total overhead percentage). Example with 10% project overhead + 10% company overhead: $120,000 ÷ 0.80 = $150,000 (multiplying by 1.20 understates the bid).
Owned equipment cost charged to a projectHourly unit cost = total yearly cost of the machine (depreciation, maintenance, operating costs, taxes, fees, insurance) ÷ hours of annual use; project cost = unit cost × project hours. Example: $48,000 ÷ 1,200 = $40/hr; $40 × 60 = $2,400.
FUTA tax when state unemployment taxes are paid in full and on time (non-credit-reduction state)FUTA applies only to the first $7,000 of wages per employee; 6.0% rate less the maximum 5.4% state credit = 0.6% effective. Example: $7,000 × 0.006 = $42.
California daily overtime under Labor Code § 510(a)First 8 hours at the regular rate; hours over 8 and up to 12 at 1.5 × regular rate; hours in excess of 12 in one day at 2 × regular rate. Example at $20/hr for 14 hours: (8 × $20) + (4 × $30) + (2 × $40) = $360.00.
