What Are Common Personal Finance Myths That Cost You Money?
Myths about money are sticky. They come from family lore, viral social posts, or partial truths repeated so often they feel true. In my 15 years working with clients, I’ve seen a handful of these beliefs repeatedly turn sound finances into wasted opportunities. Below I debunk the most damaging myths, explain why they’re wrong, and give clear, actionable steps to protect your money.
Myth 1 — You must have a 700+ credit score to get a mortgage
Reality: Lenders use many factors—not just a single score—when you apply for a mortgage. Loan types such as FHA, VA, and some conventional programs accept lower scores when other credit factors (stable income, low debt-to-income ratio, good payment history) are solid. Declaring a rigid cutoff prevents people from exploring options (and government-backed programs) that may fit their situation.
Cost of belief: Waiting to hit an arbitrary score can delay homeownership, raise housing costs over time, and prevent building home equity.
Practical steps:
- Check your reports at AnnualCreditReport.com to find and fix errors before applying.
- Lower credit card balances to improve utilization (a leading factor in many scoring models).
- Talk to multiple mortgage lenders about program eligibility, including FHA or VA loans.

Myth 2 — All debt is bad debt
Reality: Debt is a tool, not a moral failing. The key is the cost of borrowing versus the expected return on the use of the funds. Student loans, mortgages, and some small business loans can be investments in future earning capacity or appreciation. High-interest consumer debt—credit cards, payday loans—is the kind to eliminate quickly.
Cost of belief: Avoiding all debt can cause people to forgo education, a starter home, or business expansion—decisions that might have produced net financial gains.
Practical steps:
- Prioritize paying down high-interest debt first (credit cards generally). The Consumer Financial Protection Bureau explains how interest compounds and how payoff order matters (CFPB).
- Create a written plan: list debts by interest rate and balance, then target the highest-cost balances while maintaining minimums on others.
Myth 3 — You need to be wealthy to start investing
Reality: Modern investing platforms, fractional shares, and low-cost index funds let people start with very small amounts. Time in the market, compound growth, and regular contributions usually matter more than a large initial sum.
Cost of belief: Delaying investing loses years of compound growth and forces you to save much more later to reach the same financial goals.
Practical steps:
- Open a tax-advantaged retirement account (401(k), IRA) even with small contributions—take advantage of employer matches first.
- Use low-cost index funds or a robo-advisor to start with modest amounts. FINRA offers clear investor education on building diversified portfolios with limited capital (FINRA).
Myth 4 — You should pay off all debt before investing
Reality: Balancing debt repayment with investing is often optimal. If your high-interest debt (e.g., credit cards) costs more than typical long-term investment returns, prioritize paying it off. But paying off low-interest debt (e.g., some mortgages or federal student loans) before contributing anything to retirement can forfeit tax benefits and employer matching funds.
Cost of belief: Missing employer 401(k) matches or tax-advantaged retirement contributions is effectively leaving compensation on the table.
Practical steps:
- Capture your employer match first, then direct surplus funds toward high-interest debts.
- Revisit the decision if you refinance, change jobs, or interest rates shift.
Myth 5 — Checking and savings accounts should always be separate, so keep cash out of investments
Reality: You need both liquidity and growth. An emergency fund in a safe, accessible savings vehicle (or short-term CD/high-yield savings) is different from long-term money invested for growth. Treat each dollar with a purpose.
Cost of belief: Either keeping too much idle cash (losing to inflation) or having no emergency cushion (forcing costly borrowing after a shock).
Practical steps:
- Keep 3–6 months of essential expenses in an emergency fund, then direct additional savings toward retirement and long-term goals.
- Use high-yield savings accounts for the emergency fund to minimize inflation loss.
Myth 6 — Credit cards rewards are free money
Reality: Rewards are valuable only when you pay your balance in full each cycle and avoid interest and fees. Carrying a balance cancels most reward benefits; the interest rate on unpaid balances typically outweighs the rewards value.
Cost of belief: Paying interest charges erodes or surpasses any rewards earned.
Practical steps:
- Use rewards cards only if you can pay the full statement balance each month.
- Compare annual fees to expected rewards; a big-fee card requires consistent travel or spending patterns to be worthwhile.
Myth 7 — Renting is always throwing money away
Reality: Renting can be the smarter financial move depending on housing costs, job mobility, expected length of stay, and local market conditions. Buying has transaction costs, maintenance, property taxes, and insurance that can offset the benefits of building equity, especially in the short term.
Cost of belief: Forcing home purchase before you’re ready can lead to overpaying, buyer’s remorse, or being house-poor.
Practical steps:
- Do a rent vs. buy analysis that includes transaction costs and projected residence time.
- Keep flexibility in mind when career or life changes are likely.
Myth 8 — A financial advisor is only for the wealthy
Reality: Advisors can add value across income levels—through tax planning, investment selection, insurance needs, and behavioral coaching. Fee-only planners often offer hourly or project-based services so you can pay only for what you need.
Cost of belief: Trying to DIY complex tax decisions, investment mistakes, or improper insurance coverage can be costlier than paying for professional help.
Practical steps:
- If you’re unsure where to start, schedule a single consultation to get a prioritized action plan.
- Look for credentialed planners (CFP®) and understand fee structures (AUM, hourly, flat). FINRA provides resources to evaluate advisors (FINRA).
Quick decision checklist (practical actions)
- Review your three credit reports and correct errors (AnnualCreditReport.com).
- Create a prioritized debt list by interest rate; tackle high-interest balances first.
- Contribute enough to your employer retirement plan to get any match.
- Build a 3-month emergency fund, then expand to 6 months if your job is variable.
- Start investing with low-cost index funds or fractional shares if you can’t afford a lump sum.
- Re-evaluate annually or after big life changes (new job, marriage, home purchase).
Common real-world examples (short case studies)
- A young professional delayed retirement savings until age 35 to “get debt-free.” By starting at 25 with $50/month, they’d have had roughly twice the retirement savings by 65 due to compounding—small early contributions make a big difference.
- One client believed a 700 score was required and delayed applying for first-time homebuyer programs. When they spoke with a mortgage broker, an FHA path with a lower down payment and flexible score threshold was available.
These cases reflect patterns documented by consumer agencies and research—credit scoring models weigh utilization and payment history heavily, not just a single magic number (see CFPB & Federal Reserve research).

Frequently Asked Questions
Q: Will a single late payment destroy my credit?
A: No—one late payment can lower a score, but sustained missed payments and collections cause the most damage. Correcting errors on your reports is often the best first step (AnnualCreditReport.com).
Q: Should I always prioritize debt repayment over investing?
A: Not always. Prioritize high-interest debt, but also capture employer retirement matches and maintain an emergency fund.
Q: Is DIY investing a bad idea?
A: Many people succeed with low-cost index funds and solid asset allocation. The common mistake is emotional trading or chasing performance. If you lack the time or discipline, a fee-only advisor or robo-advisor is a cost-effective alternative (FINRA).
