Where Should Your Next $100 Go? — Rank Debt, Savings, Match, and Investing

Compare the real return on an unmatched 401(k) match, paying down high-interest debt, high-yield savings, and investing — side by side, so the choice is math, not a gut call.

Quick answer: Rank the best use of extra cash by comparing guaranteed employer-match return, debt-payoff avoided interest, high-yield savings APY, and expected investment return. Enter Extra Amount, Unmatched 401(k) Match Available, Employer Match Rate (%), and High-Interest Debt to Pay Down to personalize the estimate. It returns Best Available Return, Employer Match Return, and Debt Payoff Return so you can compare the impact before choosing a next step. Use it to compare cash flow, interest, liquidity, and next-account choices before moving money.

Unmatched 401(k) employer match

A 50.00% return -- worth about $50 over a year if this held steady.

Ranked Options

  1. #1Unmatched 401(k) employer match

    An instant, guaranteed return -- your employer adds this the moment you contribute, before any market risk.

    50.00%$50/yr
    Guaranteed

  2. #2Pay down your highest-rate debt

    A guaranteed return equal to the interest rate you stop paying -- no market exposure.

    22.99%$23/yr
    Guaranteed

  3. #3Taxable brokerage / index fund

    A long-run planning assumption, not a guarantee -- real returns vary year to year and can be negative.

    7.00%$7/yr
    Market-dependent

  4. #4High-yield savings

    Today's widely available high-yield APY -- FDIC-insured up to coverage limits, no market risk.

    4.20%$4/yr
    Near-certain

Ranks by annualized return only -- it doesn't weigh liquidity needs, an unfunded emergency fund, tax treatment, risk tolerance, or your own priorities. "Guaranteed" returns (match, debt payoff) carry no market risk; "market-dependent" returns can be negative in any single year even if the long-run average is higher. Not financial advice.

Frequently Asked Questions

Everything you need to know.

Should I always take the highest-return option?
Not necessarily. This ranks by annualized return only — it doesn't account for whether you have an emergency fund yet, how liquid you need the money to be, or your own risk tolerance. An unfunded emergency fund can outrank all four options here even if its "return" isn't the highest, because the value of having accessible cash in an emergency isn't captured by a percentage.
Why does an employer match usually rank first?
Because it's both guaranteed and immediate — if your employer matches 50% of your contribution, that dollar is worth 50% more the instant you contribute it, with no market risk and no waiting period. Very few other financial moves offer a guaranteed, instant return that high.
Is the Where Should Your Next $100 Go? — Rank Debt, Savings, Match, and Investing free to use?
Yes. SwitchWize calculators are free, and you do not need an account to run scenarios or view the result.
Does using the Where Should Your Next $100 Go? — Rank Debt, Savings, Match, and Investing affect my credit score?
No. Using a calculator does not trigger a credit check. A credit impact can occur only if you apply directly with a lender, card issuer, or provider.
Are the results personalized financial advice?
No. Calculator outputs are educational estimates based on the inputs you enter. Review assumptions and confirm terms directly with providers before making a financial decision.
What should I do after seeing the result?
Use the recommendation module on this page to see today's best high-yield savings rates, or run Money Map to compare this banking & savings decision with your other opportunities.
How does SwitchWize choose related offers?
Related offers are matched by the calculator surface (savings) and ranked using SwitchWize data such as rate, fees, trust signals, product fit, and switching friction. Paid relationships do not change organic ranking order.
How fresh are the rates and offers shown?
Rate and offer data is reviewed on a recurring cadence and every offer module shows review context or links to the methodology and disclosure pages.
Where can I see the ranking methodology?
The SwitchWize methodology page explains how rate freshness, editorial review, affiliate disclosure, and category ranking factors work.
Can Money Map use this result?
Yes. Money Map is the broader diagnostic path: it compares savings, mortgage, cards, and debt so you can see whether this calculator result is your highest-impact next move.

Why This Matters

Most people default to whichever option feels most responsible (paying down debt) or most familiar (a savings account), without comparing the actual return. An unmatched employer match is often a guaranteed 50-100% instant return that beats everything else on this list — and it's easy to miss if you're not comparing options directly.
