What is the LEAST accurate technique to use for cash flow analysis?

NPV
IRR
payback period
discounted cash flow

Payback period is the least accurate cash flow analysis technique because it does not take into consideration the time value of money. Payback period is the amount of time that it will take to recoup the initial investment in the project. To calculate the payback period, you can sum the expected cash inflows and compare them to the initial project investment. This allows you to determine how long it will take for the initial investment and the total cash inflows to be equal.

Discounted cash flow is a more general term that refers to calculation of future cash flows adjusted for the time-value of money. Different methods, including the Yield method and the Net Present Value (NPV) method, can be used.

The internal rate of return (IRR) is simply the project's return expressed as an interest rate. IRR represents the discount rate when the present value of cash inflows is equal to the original investment, in other words the discount rate when NPV equals zero.

The NPV is a calculation that you can use to evaluate what a project is currently worth.
