In my opinion, the only sensible debt reduction method is to make sure you don't incur any penalties first, and then pay off the debts with the highest interest payments next. Any other strategy just means that you are adding to the debt with higher interest payments. The real answer is to avoid debt in the first place. Go out and mow someone's lawn or collect scrap metal, or do some other job to get the extra cash. It also helps to reduce your outgoings. There is an old adage " A penny saved is a penny earnt". It shows how old that is by the reference to pennies. Don't buy unhealthy McDonalds rubbish, but cook some real food, it's cheaper and better for you. Cut out cigarettes and vaping stupidity, and reduce your alcohol consumtion as well - you'd be shocked if you worked out how much you spent on those if you are a heavy user.
Many people are in debt because they buy what they don't need. Some people have the habit of buying the advanced model of their phones, cars, and other accessories. This habit has been built over the years and it has become a tradition to them. So they spend on these items without considering their debt profile. Meanwhile, the old models or editions are stronger and durable than the new ones. I will become indebted if the loan or credit is a necessity but I will never take a loan for pleasure or to satisfy a want.
The best strategy to be free from debt is to avoid unnecessary expenses. Cut some major expenses such as house rent by owning your house. Buy quality products that can last for a long time. Learn an additional skill that can increase your income. And don't take a loan to service or pay for another loan.
I also get this error sometimes. But there is another situation. If I delay the things I need, I get a raise because of inflation and I have to buy it very expensive later. In order not to experience this, others are added to my debts. Of course, the end of my debts is also delayed because of this.
Sometimes your old phone or computer has expired and you need to get a new one. When all of these coincide at the same time, this payment method you have made may fail. Sometimes all your plans in life don't work so I can't fully stick to this plan.
The best strategy to get out of debt is to avoid unnecessary spending. I know this, but I can buy things because what is unnecessary today may be necessary tomorrow. When I do this in a planned way, there is no problem.
