The upfront cost and the discount rate you want to evaluate it against.

Updates instantly, with each year's cash flow discounted back to today's value individually.
Whether a series of future cash flows, once discounted back to today's dollars at your chosen rate, is worth more or less than what you'd have to invest upfront to get them. A positive NPV means the investment clears that discount rate; a negative NPV means it doesn't.
That depends entirely on your own required return or cost of capital — a personal savings goal, a company's weighted average cost of capital, or simply what you could otherwise earn on the money elsewhere. This tool doesn't recommend a rate; it just shows you the math for whatever rate you enter.
Yes — enter a negative number for any year where you expect an additional cost rather than income, such as a planned repair or reinvestment.
Yes. Every calculation happens entirely inside your browser tab — your investment amount and cash flow figures are never sent anywhere.
No, this is a calculation based on the cash flows and rate you enter. It doesn't account for taxes, inflation beyond what's built into your discount rate, or risks specific to your situation.
