Tooltips for Key Concepts

Discount Rate - The expected rate of return or cost of capital. It reflects how much future cash flows are ‘discounted’ to account for the time value of money. A higher rate reduces future value more.

Cash Flow - The amount of money flowing in or out of your project each year. Positive cash flow means income or savings, while negative means expenses or losses.

Net Present Value (NPV) - The total value of all future cash flows adjusted to today’s money using the discount rate. A positive NPV means your project is profitable — a negative one suggests a potential loss.

Initial Investment - The upfront cost of the project or investment. This includes all one-time expenses like equipment, setup, or development costs.

Number of Years - How long the project will generate cash flows. This sets the time horizon for your financial analysis.

Yearly Cash Flows - Enter the amount of income or savings the project will generate for each year. This should be based on realistic projections.
