The true method of reducing any debt is to aggressively repay the money borrowed. The interest will automatically reduce, because it is calculated on a daily basis, on the outstanding balance. Therefore, the money you are not paying to interest is paying down your balance. This works for all debt from a small credit card balance to a mortgage. The key however, is to see what you are doing. That starts with a simple budget. See my 2020 interest activity on my credit card, pictured.
