I have a system that I like to call "Baby Steps"
Baby step 1: Save $1,000 for an emergency fund.
Baby step 2: Pay off debt using the Debt Snowball method. Regardless of interest rates, take your debt and pay the minimum on all except the smallest one. Take any extra payments to pay that off first. Once that is done proceed to the next smallest and so forth. (all debts other than mortgage)
Baby step 3: Save enough money to cover 3 to 6 months of expenses.
Baby step 4: 15% of household income into Roth IRA and pretaxed income vehicles (401 k or b).
Baby step 5: Save for kids' college
Baby step 6: Pay off house early
Baby step 7: Build wealth and give
Ok, these aren't my creations. This is the Dave Ramsey plan. If you'll not familiar, I highly recommend him for getting out of debt only. He's not much help with financial instruments. He's more of an archaic, only pay cash type, but helps millions of people, and once you get out of debt, you can move on to a financial advisor to sock away for retirement.
