What is the Savings Calculator?

Frequently Asked Questions
How big should my emergency fund be?
Three to six months of essential expenses is the common recommendation, more if your income is variable.
Where should I keep short-term savings?
High-yield savings accounts and money-market funds are typical: liquid, low risk and paying some interest.
How much should I save each month?
A common guideline is 20% of income, but the right number depends on your goals. Work backwards from your target amount and time frame.
What is an emergency fund and how big should it be?
It is cash set aside for unexpected expenses. Most planners suggest three to six months of essential living costs.
What is the rule of 72?
Divide 72 by your annual interest rate to estimate how many years it takes to double your money. At 6%, that is about 12 years.
