The Federal Reserve raised interest rates by a quarter of a percent Wednesday, signaling a strengthening economy.
The New York Times explains the country's central bank set the interest rate for overnight lending at a range of 0.75 percent to 1.0 percent. It had been 0.5 percent to 0.75 percent.
It's the second time in three months the Fed has raised its key interest rate. Before that, the rate hadn't gone up since 2006.
So, what does a higher interest rate actually mean?
First, you could make more money from a savings account — assuming the economy keeps improving and the Fed continues to raise the interest rate.
Higher rates can also attract more foreign investors. That usually leads to a stronger dollar and makes it more expensive for other countries to import U.S. goods.
It also means interest on credit card debt will go up.
A higher interest rate could also lead to higher mortgage rates, but the two aren't directly connected.
The Fed plans to raise rates again by a quarter point twice more this year and three times next year.
