There’s a proven order for where your money should go — but it’s buried in flowcharts and forum posts. InvestPath turns it into three steps.
Income, age, what you can invest, and whether you have an employer match or an HSA. Rough numbers are fine.
A personalized waterfall showing how many dollars go into each account, and the one-sentence reason why.
A projection of the age you could reach financial independence — and how each change moves that date.
This is the “financial order of operations” — the sequence that captures free money and tax breaks before everything else. The calculator below sizes each step to your income.
A small cash buffer so an unexpected bill doesn’t become credit-card debt. Keep it in savings, not invested.
A 100% instant return — the best deal in personal finance. Never leave free money on the table.
Debt above ~7% (credit cards) beats any expected market return. Clearing it is a guaranteed, tax-free win.
Enough cash to cover a job loss without selling investments at the worst possible time.
The only triple-tax-free account: deductible going in, grows untaxed, and tax-free for medical costs.
Tax-free growth and withdrawals. Contributions can come out penalty-free, so it doubles as a backup fund.
Fill the rest of the annual limit with pre-tax dollars that lower your taxable income today.
No limits, fully accessible — the bridge that funds the years before you can touch retirement accounts.
Everything updates live as you type. Nothing is sent anywhere — it all runs in your browser.
Rough numbers are fine.
Your savings rate matters more than your income or your returns. Drag it.
Follows the r/personalfinance prime directive — sized to your numbers.
FIRE = the day your investments cover your spending forever (the 4% rule).
Great tools exist — but they either give you a number with no “what next,” or bury the logic in a static image.

In order: a small starter emergency fund, your 401(k) up to the full employer match, high-interest debt, a full 3–6 month emergency fund, then max your HSA (if eligible), a Roth IRA, your 401(k), and finally a taxable brokerage account. This captures free money and tax advantages before anything else. The calculator above sizes each step to your income.
Contribute to your 401(k) up to the employer match first — that’s an instant 100% return. After the match, a Roth IRA usually comes next for its tax-free growth and flexible withdrawals, and then you go back to maxing the 401(k).
The 4% rule estimates you can safely withdraw about 4% of your invested portfolio each year in retirement. So your “FIRE number” target is roughly your annual spending × 25.
No. InvestPath is a free educational tool. It uses widely-accepted guidelines (like the r/personalfinance prime directive and the 4% rule) but doesn’t know your full situation. For personalized advice, talk to a fee-only fiduciary advisor.
