1. What Is Present Discounted Value?

Present Discounted Value (PDV) is a financial concept that calculates the current worth of a future stream of cash flows, discounted at a specific rate. It accounts for the time value of money, recognizing that money available today is worth more than the same amount in the future.

2. How Does The Calculator Work?

The calculator uses the PDV formula:

Where:

• \( CF_t \) — Cash flow at time period t (currency)
• \( r \) — Monthly discount rate (decimal)
• \( t \) — Time period in months
• \( n \) — Total number of periods

Explanation: The formula discounts each future cash flow back to its present value using the discount rate, then sums all these present values.

3. Importance Of PDV Calculation

Details: PDV is crucial for investment analysis, capital budgeting, bond pricing, and any financial decision involving future cash flows. It helps compare investment opportunities with different cash flow patterns.

4. Using The Calculator

Tips: Enter cash flows as comma-separated values (e.g., "100,200,300"), monthly discount rate as a decimal (e.g., 0.01 for 1%). All values must be valid (discount rate ≥ 0, cash flows numeric).

5. Frequently Asked Questions (FAQ)

Q1: Why use monthly discounting instead of annual?
A: Monthly discounting provides more precise results for cash flows that occur monthly, which is common for many financial products and investments.

Q2: How do I convert annual rate to monthly?
A: Divide the annual rate by 12. For example, 12% annual rate becomes 1% monthly rate (0.01 as decimal).

Q3: What if cash flows are irregular?
A: The calculator handles irregular cash flows by allowing you to input any sequence of values separated by commas.

Q4: Can PDV be negative?
A: Yes, if future cash outflows exceed inflows, or if early outflows are followed by smaller inflows.

Q5: How does PDV relate to NPV?
A: Net Present Value (NPV) is PDV minus the initial investment. PDV focuses only on future cash flows.
