How much should I save each month?

Focus on any amount that you can save consistently. Overall, there is no one answer for how much you should have in savings, but an ideal target for an emergency fund is enough to cover three to six months' worth of basic expenses. If you’re able to save 20% of your take-home income each month, for example, you may be well on your way. But it’s more important to be consistent, even if it means saving a smaller amount each month. With time, you can still reach your savings goal.

How do you calculate interest on a savings account?

Multiply the account balance by the interest rate for a select time period. The result is the amount of simple interest the account earns in that time period.

APY calculator: Determining annual percentage yield

When you earn interest in a bank account, that money starts to earn interest as well. This is known as compounding. The higher the interest rate and the more times an account compounds, the higher the yield will be. APY includes compound interest and reflects the total amount of money earned over a period of one year.

Along with entering the interest rate, adjust the compound frequency to daily, monthly or annually to see how each period affects the yield.

How can I save $5,000?

If you start with zero and put away $135 a month (about $33.75 a week) in a savings account that compounds monthly and earns a 4% annual interest rate, you would save more than $5,000 in three years. Use this savings calculator to compare other contribution amounts and yields.

How much interest can you earn on $10,000?

If your savings account earns only a 0.01% annual interest rate, which is common with large banks, your earnings after a year would be $1. Put that $10,000 in a high-yield savings account that earns 4%, for the same amount of time, and you can earn more than $400.

How much will a savings account grow?

The answer depends on the interest rate, deposit balances and time. The higher the rate, the faster a savings account will grow. Also, because of compounding, the more often interest is deposited into a savings account, the more the overall balance will grow. An account that compounds daily can grow slightly faster than one that compounds less frequently, such as once a month. To get the most growth over time, put your money in an account with a high yield that compounds daily.
