Common Questions

Q

Should I pay off debt or start investing?

Pay off high-interest debt (credit cards above 7%) first. For low-interest debt (mortgage, student loans under 5%), you can invest simultaneously since market returns historically exceed these rates.

Q

Should I pay off debt or invest first?

Compare interest rates: pay off debt with rates above 7% before investing (credit cards, personal loans). For debt below 5% (most mortgages, federal student loans), invest simultaneously — historical market returns average 7-10%. For debt between 5-7%, do both: match your 401(k) employer contribution, then throw extra at debt. The math favors investing, but being debt-free has psychological value.

Q

What is the debt avalanche method?

The debt avalanche method pays minimum payments on all debts, then directs all extra money toward the debt with the highest interest rate first. Once that debt is paid off, you roll that payment to the next highest-rate debt. It is mathematically optimal — you pay the least total interest over time. The downside is that high-balance, high-rate debts can take a long time to pay off, testing your motivation.

Q

What is the debt snowball method?

The debt snowball method pays minimum payments on all debts and directs extra money toward the smallest balance first, regardless of interest rate. Each payoff provides a motivational win that keeps you going. You then roll that payment to the next smallest debt. Research shows the psychological momentum often leads to faster overall payoff than the mathematical approach, especially for people who struggle with motivation.

Q

What is debt consolidation and is it a good idea?

Debt consolidation combines multiple debts into a single loan — ideally at a lower interest rate. Options include personal loans, home equity loans, and balance transfer credit cards. It simplifies payments and can reduce total interest if you qualify for a lower rate. The risk: it does not fix the spending habits that caused the debt, and using your home as collateral in a home equity loan adds significant risk.

Q

Should I pay off debt or invest?

A practical rule: always capture your full employer 401k match first (it is a 50–100% instant return). Then pay off high-interest debt (generally anything above 6–7%). After that, split money between mid-rate debt and investing. Low-interest debt like a mortgage (3–4%) can reasonably be maintained while investing, since long-term stock market returns historically exceed that rate. Context always matters.

Q

Should I invest before paying off high-interest debt?

Generally no — if your debt carries an interest rate above 7–8%, paying it off first is the equivalent of a guaranteed, risk-free return at that rate. The stock market historically returns around 7–10% annually with significant short-term volatility. Paying off a 22% APR credit card balance is a guaranteed 22% return. Always capture your 401k employer match first (even while in debt), then prioritize high-interest debt repayment.

Q

How do I create a debt payoff plan?

Start by listing all debts with their balances, interest rates, and minimum payments. Choose a strategy: avalanche (highest rate first, saves the most money) or snowball (smallest balance first, best for motivation). Make minimum payments on all debts. Direct every extra dollar toward your target debt. Use a free calculator at undebt.it or Bankrate to model your exact payoff timeline and total interest cost.

Key Terms

Debt Snowball Method

A debt repayment strategy that pays off the smallest balance first, then rolls that payment to the next smallest. Provides psychological wins through quick victories. Mathematically less efficient than the avalanche method but has higher completion rates due to motivational momentum.

Debt Avalanche Method

A debt repayment strategy that targets the highest-interest debt first, minimizing total interest paid. Mathematically optimal but requires discipline — the first payoff may take months. Best for analytically-minded people motivated by saving money over quick wins.

Debt-to-Income Ratio (DTI)

Monthly debt payments divided by gross monthly income. Lenders use DTI to assess borrowing capacity. Under 36% is healthy; 36-43% is acceptable for most mortgages; above 43% limits loan options. Reducing DTI before applying for a mortgage can save thousands in interest over the loan term.

Debt-to-Income Ratio (DTI)

Monthly debt payments divided by gross monthly income, expressed as a percentage. Lenders use DTI to assess loan affordability; most mortgage lenders prefer a back-end DTI below 43%.

Debt Consolidation

Combining multiple debts into a single loan or payment, ideally at a lower interest rate. Consolidation simplifies repayment and can reduce total interest paid, but extending the repayment term can increase lifetime cost.

Refinancing

Replacing an existing debt with a new loan at different terms, typically to obtain a lower interest rate, reduce monthly payments, or change the repayment period. Refinancing works well when rates have dropped or credit has improved.

Debt Payoff Calculator

A tool that shows how extra payments or different strategies (avalanche vs. snowball) affect total interest paid and the time to become debt-free. Using a calculator helps bettors choose the most cost-effective payoff plan.

Good Debt vs. Bad Debt

Good debt finances assets that may appreciate or generate income (mortgages, student loans); bad debt funds depreciating items at high interest rates (credit card balances, payday loans). The distinction guides priority in debt payoff.
