1st things 1st:
A: If you are just starting out in your life
1: Invest in your future early in your career. If you put in $5,000 a year for 10 years (from 20-29) into an IRA Mutual fund that earns an average of 12% (average of the S&P 500) and then never put another dime into your IRA, but don't touch it until you retire at 62 (or maybe 65)………....You will have more money at retirement than if you put $10,000 a year into the same IRA per year from 30 years old until you retire.
2: Don't go into debt, except to buy a house. My wife and I did bought a lot of things on credit, and I am now 56 and should get out of debt this year for the 1st time since I was 25 years old. DON'T DO IT. Don't buy a new car every few years, don't buy ANYTHING ON CREDIT. STAY OUT OF DEBT.
3: Put 15% of your income into your company 401K up to their match (if they match 4% then put in 4% of your income; if they match 2% then do 2% etc.) then put $4,000 of your income into an ROTH IRA in a good mutual fund (or $8,000 if you are married) then put the rest (up to 15% of your income) into the 401K. If you do that the entire time you work you can retire with well over $5 million if not $10-25 million for retirement.
4: Pay cash for things that you save up for. Don't buy a new car, the average car payment is over $500 a month: put $500 a month into a Mutual fund for 10 years, after you save up and buy a $10K car for cash, and in 10 years you should have over $100K. Then when your car needs replacing, take $10-15K out of Mutual fund, buy another used car, and keep putting $500 a month into Mutual fund (Above retirement). That will be another $2 million or so when you retire.
{I hate to say this for those that have family members that work in banking}
5: Don't go to a banker or Credit Union Investment person for investment advice: They work for the bank or Credit Union, they get credit or bonuses when they get you to invest in their products: and when I was last in the lobby of my Credit Union the best CD was 2.9% for 5 years on $50K: That doesn't even match inflation.
Go to a true financial advisor: a Mutual fund my brother in law advised my to buy into for our ROTH IRA (You can use almost anything to invest in for a ROTH IRA) earned us 11.7% during former President Obama's terms in Office (my 401K made 9.2% during the same time frame): but the last 3 years under President Trump that same Mutual Fund only made a lousy 29%. My 401K (not counting what I put in or the match) made 59%: it dropped to 7% from April to July of this year, but it back up to 18% since July.
I wish we were totally out of debt they last 12 years and I could have been putting the full 15% into retirement, and the last 6 years an additional $15K more to make up for my retirement since I am older. But when I get out of debt later this year I am maxing everything out.
B: If you are older and in debt: GET OUT OF DEBT AS SOON AS POSSIBLE, then start dumping 15% of your income into retirement (plus if you can afford to the extra $15k. Why retire broke? Retire as a millionaire. My Uncle and Aunt did it at 56, they retired with $5 million and live off the interest:, their best income was $95K a year. Their kids just wish they taught by more than example (and so do I).
My dad is 89 years old, still living in the house that he and my mom bought in 1958, still makes more off of his retirement than off of Social Security: and he retired in 1991. His best income year was $41,500. The only thing he ever bought on credit was his $14,800 house (that is now worth $325,000.
If you are out of debt except your house pay it off as soon as you can: don't keep the house payment for the tax break. Think about I: "I want to pay the bank $3,500 a year in interest so that I can get a $2,000 tax break": (and that is only if you get more than the $24,000 joint tax deduction, which less than 10% of married Americans got last year). I want to pay the bank $3,500 in interest so that I don't get anything back in taxes???? But people do it because their parents taught them to do it; and bankers tell them to do it.
Pay off your house: in 2008 when the housing market crashed 100% of houses foreclosed on by the banks had a mortgage: or in the reverse 0% of people that owned their house outright had the bank take them away.
How many people are planning on living only on Social Security when they retire? I hope no one thinks they will be able to
