How this service works
Net present value of a series of cash flows discounted at a per-period rate. cashflows[0] is the time-0 flow (typically the initial outlay, negative).
Output
Returns the computed net present value as a single numeric figure, representing the sum of all discounted cash flows including the time-0 outlay. A positive NPV indicates the investment adds value; negative NPV indicates a loss relative to the discount rate.
Example use cases
Capital budgeting project evaluation
“I'm considering a manufacturing upgrade that costs $200,000 today and is expected to generate $60,000, $70,000, $75,000, and $65,000 over the next four years. Can you calculate the NPV at a 9% annual discount rate so I can decide whether it's worth it?”
Real estate investment NPV check
“I'm looking at a rental property that requires a $300,000 initial investment and will yield $30,000 per year for 10 years. What's the net present value of those cash flows at a 7% discount rate per year?”
Startup funding round analysis
“Our startup is evaluating a product line: we'd spend $80,000 now, then earn $10,000, $25,000, $40,000, and $50,000 over four years. Please compute the NPV using a 12% per-period discount rate.”
