HP-12C NPV (VPL) cash flow
Net Present Value (NPV) brings every cash flow back to time 0: NPV = Σ CF_t / (1+r)^t. The HP-12C keystrokes are straightforward. You enter the discount rate with [i], then CFo (usually the negative initial outlay) followed by each CFj, and finish with [f] [NPV]. A positive NPV means take the project; a negative one means walk away.
Here the discount rate (cost of capital or WACC) is something you feed in, whereas IRR works the other way and solves for that rate. Because NPV grows with project size, it tends to win when you have to pick between mutually exclusive options. IRR returns a percentage, which is handier for ranking. You'll see both in CFA, ANBIMA CEA/CFG and the finance core of most MBAs.
Applications
Capital budgeting, valuing M&A targets, real estate work with cap rates, BNDES infrastructure deals, PMP project finance, and CFA Level 1-2.
FAQ
Which rate to use? For company projects, use the cost of capital (WACC). For personal decisions, use your opportunity cost.
NPV vs IRR which to prefer? Lean on NPV when scale matters, and reach for IRR when the projects you're comparing require the same investment.
How to handle terminal value? Tack on a Gordon growth perpetuity, discounted back to year n: TV = CF_n+1 / (r-g) / (1+r)^n.

Peak Flow Rate (PHF)
Calculate the peak flow rate of a roadway, q = V ÷ PHF, dividing the hourly volume V (vehicles/h) by the peak hour factor PHF (between 0 and 1, the ratio of the hour's volume to four times the busiest 15-minute volume). The result, in vehicles/h, is the equivalent flow rate of the busiest 15-minute period — always greater than or equal to the hourly volume, since traffic does not arrive uniformly. It is the design flow used in capacity and level-of-service analysis by the HCM, since sizing by the hourly average would underestimate the peaks. Enter the hourly volume and the peak hour factor.
