What order should I put my money in?
Roughly: a starter cash buffer, then the full employer match, then any debt above about 8%, then the rest of the emergency fund, then tax-advantaged investing — ordered by the certainty-adjusted return of the money going in.
The ordering principle is worth stating because it explains every step. Money should go where it earns the most per unit of risk taken, and a guaranteed return outranks an expected one at the same headline rate. An Employer matchMoney your employer adds to your plan in proportion to what you contribute, typically up to a few percent of salary. Declining it is declining part of your stated compensation.Read the evidence on this → is a certain 50-100%; clearing a 20% card is a certain 20%; expected equity returns are neither certain nor 20%.
The buffer comes first in a small amount, not a large one, because its job at that stage is to stop the next unexpected bill from going straight back onto the card you are trying to clear. Completing it can wait until after the highest-rate debt is gone.
The plan on this site generates exactly this ordering from your own figures, including where your specific debts fall relative to Expected returnThe probability-weighted average of what could happen — not a prediction of what will. A strategy can have the higher expected return and still be the wrong choice for someone who cannot survive its bad tail., rather than from a generic ladder.
When the answer is different
- A vesting cliff you are unlikely to reach, or an employer plan with genuinely high fees, changes where the match sits.
- Irregular income moves the buffer up the list — the ordering assumes a shock is unlikely to arrive during the months you are clearing debt.

The research this rests on
Each note states its claim, rates how strong the evidence actually is, and lists the conditions under which it fails.
- Unclaimed employer matches are the clearest mistake in personal finance
A meaningful share of eligible employees fail to contribute enough to collect the full employer match, forgoing money with no offsetting cost. (strong)
- Clearing debt is a guaranteed return; investing is not
Paying down a debt returns its interest rate with certainty, which should be compared to expected investment returns on a risk-adjusted basis, not a raw one. (strong)
- A cash buffer is what makes every other decision survivable
A large share of households cannot absorb a moderate unexpected expense, and that fragility forces asset sales and high-interest borrowing at the worst moments. (strong)
- Tax drag is a fee you can often remove entirely
Holding the same investment inside a tax-advantaged account rather than a taxable one raises net returns with no additional risk taken. (strong)
- Defaults beat intentions, so remove the decision
Changing the default option or pre-committing future increases raises saving rates far more than education or exhortation does. (strong)
