I do something similar, and it really does make a difference.
I pay all my bills twice a month, as soon as I get paid. I divide all my payments in half (plus add $10 extra to each CC minimum) and pay that amount. The card I’m working to pay off first gets every other spare cent. By paying twice a month, my debt has really started to decrease much faster than before.
I highly recommend this practice–it does reduce the daily balance, so it helps drop your balances faster. It may take a little juggling to get it set up at first, but it’s worth it in the long run.
If you, like many people, are just having a hard time paying your bills at all, start with the minimums. It’s all about doing what you can to get rid of this albatross we’re all carrying.
