Income Statement Projections (Year 4)

Calculating Revenue:

Revenue = Units Sold × Selling Price per Unit;

  • Year 4 Revenue = 15,000 units * $10 = $150,000

Calculating Variable Costs:

Variable Costs = Units Sold × Variable Cost per Unit;

  • Year 4 Variable Costs = 15,000 units * $5 = $75,000

Calculating Gross Profit:

Gross Profit = Revenue − Variable Costs;

  • Year 4 Gross Profit = $150,000 – $75,000 = $75,000

Calculating Operating Income (EBIT):

Operating Income (EBIT) = Gross Profit − Fixed Costs;

  • Year 4 Operating Income = $75,000 – $70,000 = $5,000

Calculating Interest Expense:

  • Assuming Interest Expense for Year 4 = $10,000

Calculating Earnings Before Tax (EBT):

EBT = Operating Income − Interest Expense;

  • Year 4 EBT = $5,000 – $10,000 = -$5,000 (Loss)

Calculating Tax Expense:

Tax Expense = EBT × Tax Rate;

  • Year 4 Tax Expense = -$5,000 * 20% = -$1,000 (Tax Benefit due to Loss)

Calculating Net Income:

Net Income = EBT − Tax Expense;

  • Year 4 Net Income = -$5,000 – (-$1,000) = -$4,000 (Net Loss)

Balance Sheet Projections (Year 4)

Assets: Assume no significant changes in assets for simplicity.

Liabilities and Equity: No new debt or equity transactions for Year 4 for simplicity.

Cash Flow Projections (Year 4)

Calculating Operating Cash Flow (OCF):

OCF = Net Income + Depreciation;

  • Assuming Depreciation for Year 4 = $15,000

OCF = (-$4,000) + $15,000 = $11,000

Calculating Investing Cash Flow (ICF):

  • Assuming no new investments or capital expenditures for Year 4.

Calculating Financing Cash Flow (FCF):

FCF = Change in Debt + Change in Equity − Dividends Paid;

  • Assuming no changes in debt or equity and no dividends paid for Year 4.

FCF = $0

Calculating Net Cash Flow:

Net Cash Flow = OCF + ICF + FCF;

Net Cash Flow = $11,000 + $0 + $0 = $11,000

Calculating Ending Cash Balance:

Ending Cash Balance = Beginning Cash Balance + Net Cash Flow;

  • Assuming Beginning Cash Balance for Year 4 = $20,000

Ending Cash Balance = $20,000 + $11,000 = $31,000
