Is a savings account still worth it at 3% interest?

At 3%, a savings account definitely makes sense if you've got money sitting around that you won't need in the short term - better than earning 0% in your checking account. Whether it's the best solution depends on how long you're parking the money and whether you might get more out of fixed-term deposits or other investment options. Inflation still eats into your returns even at 3%, but for money you want to keep safe, it's still better than nothing.
