Paying Off Debt While Saving Money at the Same Time

Write down each debt you carry — credit cards, personal loans, student loans, auto loans — along with the current balance, annual percentage rate (APR), and required minimum payment. This single document becomes the foundation for every decision that follows. Without it, you are allocating money based on guesswork rather than math.

Before directing any extra money toward debt, accumulate a small cash buffer — often cited as one month of essential expenses, though the right amount depends on your situation. This reserve exists to absorb unexpected costs like a car repair or medical copay without forcing you back onto a credit card and undoing your repayment progress. For guidance on how this differs from broader savings, see our comparison of emergency funds and savings accounts.

If your employer offers a match on retirement contributions — for example, matching 50% of contributions up to 6% of salary — contribute at least enough to capture the full match before directing extra dollars toward debt. An employer match is an immediate, guaranteed return on your contribution that high-interest debt rarely outpaces. This is one of the few situations where holding some debt alongside saving is mathematically rational, as explored further in situations where carrying debt can be a rational choice.

Compare the APR on each debt against the expected return on your savings or investment options. As a general principle: if a debt's interest rate is materially higher than what your savings can earn, prioritize debt repayment. If a debt carries a low fixed rate — such as a federally subsidized student loan or a mortgage — the calculation becomes closer, and splitting contributions may be reasonable. This is not a guarantee of any outcome, since savings returns vary and future rates are uncertain. Use the comparison as a directional tool, not a precise formula.

Once you have determined how much surplus income goes toward debt each month, select a structured repayment approach. Two evidence-informed methods are widely used: the avalanche (targeting the highest-rate debt first to minimize total interest paid) and the snowball (targeting the smallest balance first for early motivational wins). Both work — the right choice depends on your financial situation and how you respond to incremental progress. Our article on the debt avalanche vs. debt snowball covers both in detail. Automate at least the minimum on every account and the extra payment on your target debt to reduce friction.

Set a recurring monthly appointment — even 20 minutes — to check balances, confirm payments posted, and reconsider your allocation if income or expenses have shifted. As debts are paid off, redirect the freed payment toward the next target (a practice sometimes called debt stacking) rather than absorbing it into discretionary spending. Over time, the share directed toward savings can increase as your debt load shrinks. A structured monthly audit, such as the one described in our monthly financial health check, can keep this process consistent.
