Saving 20k for a rainy day or something special is a popular long-term savings goal. The time it takes will depend on how much you can save on a regular basis. Our savings calculator can do the sums for you and help you put together a solid savings plan. If you want to reach your 20K goal faster, consider opening a high-interest savings account. These accounts pay interest on top of your regular savings contributions and in-turn help you save smarter. You can use the savings calculator to compare savings accounts and find the one that suits you best.
