Cash Flow Analysis Quiz

Question 1: Basic Calculation

Using the formula Cash Flow = Total Income - Total Expenses, if Total Income is $3,000 and Total Expenses are $2,500, what is the cash flow?

Solution

Using the formula: Cash Flow = Total Income - Total Expenses

Cash Flow = $3,000 - $2,500 = $500

The correct answer is A: $500

Learning Objective

Apply the cash flow formula to calculate monthly cash flow

Tip

Remember that cash flow is simply income minus expenses

Question 2: Negative Cash Flow

If Total Income is $2,000 and Total Expenses are $2,500, what is the cash flow?

Solution

Using the formula: Cash Flow = Total Income - Total Expenses

Cash Flow = $2,000 - $2,500 = -$500

A negative cash flow means expenses exceed income.

The correct answer is B: -$500

Learning Objective

Understand negative cash flow scenarios

Important Rule

Negative cash flow means you're losing money on the property each month

Common Mistake

Forgetting that expenses exceeding income results in negative cash flow

Question 3: Income Impact

If expenses remain constant but income increases, what happens to cash flow?

Solution

Using the formula: Cash Flow = Total Income - Total Expenses

If expenses stay constant and income increases:

New Cash Flow = (Original Income + Increase) - Original Expenses

This means cash flow increases by the amount of the income increase.

The correct answer is B: It increases

Learning Objective

Understand how income changes affect cash flow

Tip

Cash flow is directly proportional to income when expenses are fixed

Question 4: Expense Impact

If income remains constant but expenses increase by $200, what happens to cash flow?

Solution

Using the formula: Cash Flow = Total Income - Total Expenses

If income stays constant and expenses increase by $200:

New Cash Flow = Original Income - (Original Expenses + $200)

This means cash flow decreases by $200.

The correct answer is B: It decreases by $200

Learning Objective

Understand how expense changes affect cash flow

Tip

Cash flow is inversely related to expenses when income is fixed

Question 5: Word Problem

Sarah owns a rental property with monthly rent of $2,800. Her monthly expenses include $1,500 for mortgage, $200 for taxes, $150 for insurance, $100 for maintenance, and $50 for property management. What is her monthly cash flow?

Solution

Step 1: Calculate total income

Total Income = $2,800 (rent)

Step 2: Calculate total expenses

Total Expenses = $1,500 + $200 + $150 + $100 + $50 = $2,000

Step 3: Calculate cash flow

Cash Flow = Total Income - Total Expenses

Cash Flow = $2,800 - $2,000 = $800

Sarah's monthly cash flow is $800.

Learning Objective

Apply cash flow formula to calculate monthly cash flow from multiple income and expense sources

Tip

Always add up all income sources and all expenses before calculating cash flow
