What to do next

Build this plan in Money Map

Your action plan
  1. 1

    Build the starter buffer first

    If the starter cash gap is open, direct the next dollars there before making aggressive extra payments.

  2. 2

    Capture any employer match

    Once the starter buffer is covered, increase 401(k) contributions toward the match cap before leaving free compensation behind.

  3. 3

    Attack debt, then finish reserves

    After buffer and match, prioritize high-interest balances, then build the full emergency fund target.

Frequently Asked Questions

Everything you need to know.

What does an example Emergency Fund vs Debt vs 401(k) Match Calculator calculation look like?
Using this calculator's own default assumptions, a current emergency cash of $1,500, monthly essential expenses of $3,500 and extra cash available each month of $600 produces an estimated starter buffer gap of $2,000 and starter buffer target of $3,500. Enter your own numbers above to see how it changes for your situation.
Should I build a starter emergency fund before going after employer match?
Not always. Employer match is a guaranteed return that vanishes if you don't claim it, while a starter buffer protects you from high-interest debt in a crisis. The calculator shows both gaps and lets you weigh the monthly interest cost of debt against the match you'd capture: if debt is costing you significantly more per month than match is worth, you may prioritize debt first, then match, then reserves. The sequence depends on your numbers.
Why does the order of my next dollar matter so much?
Each dollar has a different return or cost depending on where it goes. Employer match is often a percentage gain you can't replicate elsewhere; high-interest debt costs you a percentage every month you carry it; and a starter buffer prevents you from triggering even higher-interest borrowing in an emergency. Putting your dollar in the wrong place first means you carry debt longer or miss match, both of which compound. The calculator sequences these by their actual cost and return, not by common habit.
Is the Emergency Fund vs Debt vs Match Calculator free to use?
Yes. SwitchWize calculators are free, and you do not need an account to run scenarios or view the result.

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.

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.

Why This Matters

Your next dollar can go only one place, and the order matters. Employer match is free money that disappears if uncaptured; high-interest debt compounds against you each month; and an emergency fund prevents forced borrowing. This calculator shows you the trade-offs: how much interest you're paying on debt, how much employer match you're leaving on the table, and how long it takes to reach each safety milestone, so you can sequence your cash strategically instead of guessing.

How to Use It

  1. 1Enter your current emergency cash on hand.
  2. 2Input your monthly essential expenses (housing, food, utilities, insurance).
  3. 3Enter the extra cash you can direct toward goals each month.
  4. 4Set your starter buffer target (typically one month of expenses).
  5. 5Set your full emergency fund target (typically three to six months of expenses).
  6. 6Enter any high-interest debt balance you're carrying.
  7. 7Input the annual percentage rate on that debt.
  8. 8Enter your annual salary.
  9. 9Enter what you're currently contributing to your retirement account per year.
  10. 10Enter your employer's match rate as a percentage of salary.
  11. 11Enter the salary threshold up to which the match applies.
  12. 12Review the outputs: your gaps to each milestone, the employer match available to you, the monthly and annualized cost of your debt, and how many months until you reach your starter buffer.
