It's R1500 more than you would have if leave the debt. Every bit counts. Of course if you waste the savings, then you didn't gain anything. But you haven't lost either. You have less debt.Estimated settlement amount when I log in to my account is R21,829. Contract balance is 23,386.17.
It does indeed seem as if interest savings will be negligible, but I'm also weighing up financial freedom. My plan was to always carry on like I never had that money once I paid it off, but loosening an extra noose around ones neck will be a nice feeling.
If you had to add up all of the minor gains that you passed on because they where too small, you might discover that you have missed out on a lot. It adds up. Of course if waste your little gains then the point is moot.
It's generally(not always ) the people who always take advantage of the small gains who will tend to not be wasteful.
