The interest on borrowing is usually higher than the interest earned on savings, so it might be better to pay off high interest loans and debt. We discuss this in more detail here.
If your mortgage allows you to make additional payments, you can use savings to cut years off the term and potentially save a lot of money in interest. We discuss this in more details here.
Unless you need fast access to your savings, you'll usually earn more interest if you move your money from a regular savings account into fixed rate savings (also called Term deposits).

The good news is that it's possible to invest with a conscience and have the potential to make a profit at the same time. We explain investing in more detail here.
