Questions in personal finance revolve around

• How much money will be needed by an individual (or a family) at various points in the future?
• How does this money need to be funded?
• How do I protect myself against unforseen events?

Personal financial decisions involve paying for education, financing durable goods s.a. real estate and cars, buying insurance, e.g. health and property insurance, investing and saving for retirement.
