Our collection of investing and personal finance calculators.


One of the most frequently offered advice financial planners give their clients is to save money. Unfortunately, despite the obvious importance of saving money, most of us do not know how much to save or how to save.

It’s not easy to understand how much money to put away each paycheck, how much is needed for an emergency fund, or where to invest the money. Creating a household budget is a great first step, as long as you know how to set one up.


Perhaps the biggest long-term benefit of saving money is financial security. Setting money aside removes the concern about paying for emergency or unexpected expenses such as a medical bill or much needed home repair. It can also help us realize the dream of a new car, home, or paying for a child’s college education.

Investing and personal finance calculators can add clarity to saving money goals. They can help you better understand budgeting, how much money is needed in a rainy day fund, and how much you need to save today to pay for a future expense.
