Net present value (NPV) This is how much the NPV of using loan is higher/lower than the NPV of buying with all cash. When investment yield is higher than loan rate (APR), your NPV of using loan is normally higher than the NPV of buying with all cash. This is becasue your investment income is higher than the loan interest, and it brings you more cash inflow in the long term.
