1. What is Cumulative Cash Flow?

Cumulative Cash Flow represents the total sum of all cash flows over a given period. It is a fundamental metric in financial analysis that shows the net result of all cash inflows and outflows up to a specific point in time.

2. How Does the Calculator Work?

The calculator uses the cumulative cash flow formula:

\[ \text{Cumulative CF} = \sum CF_t \]

Where:

\( CF_t \) — Individual cash flow at time period t
\( \sum \) — Summation of all cash flows

Explanation: The calculator simply adds up all the cash flow values you provide, whether they are positive (inflows) or negative (outflows).

3. Importance of Cumulative Cash Flow

Details: Cumulative cash flow analysis is crucial for assessing a project's or investment's overall financial performance, determining payback period, and evaluating liquidity position over time.

4. Using the Calculator

Tips: Enter cash flow values separated by commas (e.g., "1000, -500, 300, -200"). Positive values represent cash inflows, negative values represent cash outflows.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between cumulative and periodic cash flow?
A: Periodic cash flow shows the net cash movement for a specific period, while cumulative cash flow shows the running total across multiple periods.

Q2: How is cumulative cash flow used in investment analysis?
A: It helps determine the payback period (when cumulative cash flow turns positive) and assesses the overall profitability of an investment.

Q3: Can cumulative cash flow be negative?
A: Yes, cumulative cash flow can be negative, especially in the early stages of a project when initial investments exceed returns.

Q4: How does cumulative cash flow relate to net present value?
A: While cumulative cash flow is a simple sum, NPV accounts for the time value of money by discounting future cash flows to their present value.

Q5: What are some limitations of cumulative cash flow analysis?
A: It doesn't consider the time value of money and may not accurately reflect the true economic value of cash flows occurring at different times.
