Popular Financial Questions Americans Ask
Quick answers to the money questions that matter most
How much should I have saved for retirement by age 30?
Financial experts like Fidelity suggest having 1× your annual salary saved by 30. So if you make $60,000, that's your target. Most people aren't there yet — the median is about $18,000 for that age group — so don't stress if you're behind. Starting now matters more than catching up all at once.
Learn moreShould I pay off debt or save first?
Start with a $1,000 mini emergency fund. Then go after any debt with interest rates above 7%. Once that's gone, build your full 3–6 month emergency fund.
Learn moreIs it better to rent or buy a home in 2026?
It really comes down to how long you plan to stay. If you'll be in the same place for 5+ years, buying usually wins. But in expensive markets or if you might move, renting often makes more financial sense than people think. The break-even in most US metros is somewhere between 4 and 7 years.
Learn moreWhat credit score do I need to buy a house?
At least 620 for an FHA loan, or 680+ for a conventional loan with decent rates. Above 740 and you'll qualify for the best interest rates, which can save you tens of thousands over the life of your mortgage.
Learn moreHow much house can I afford on my salary?
The common rule of thumb is the 28/36 rule — spend no more than 28% of your gross monthly income on housing. On $75K, that works out to roughly $1,750/month total, including mortgage payment, taxes, and insurance.
Learn moreHow much of my income actually goes to taxes?
For most middle-class Americans, the total tax burden (federal + state + FICA) is 20–30% of gross income. Someone earning $85,000 typically has an effective federal rate of about 12%, plus 7.65% for Social Security and Medicare.
Learn moreDo I need life insurance?
If anyone depends on your income — a spouse, children, or co-signed loans — yes. Term life insurance is the best choice for 95% of people: a 35-year-old can get $500K coverage for about $30/month. If you're single with no dependents, you probably don't need it.
Learn moreHow much does college actually cost in 2026?
The full sticker price for 4 years at an in-state public university is about $96,000, while private universities average $233,000. But most students don't pay full price — after financial aid, the average net cost is 30–45% less.
Learn moreHow much should I invest monthly to become a millionaire?
At a 7% average return, starting at age 25 requires just $381/month to reach $1 million by 65. Wait until 40 and you'd need $1,234/month. Time in the market is your biggest advantage — start early, even if it's small.
