Will your savings last? Project your 401(k)/IRA growth, Social Security, and spending through retirement, with year-by-year detail.
For federal employees: FERS annuity, TSP growth, the supplement, sick-leave credit, and your earliest realistic retirement date.
What do extra payments really buy you? Amortization, payoff date, and interest saved, biweekly, extra monthly, or lump sums.
Are you on track for college costs? Savings projection, your state's 529 tax break (all 50 states + DC), and 529 vs Trump Account vs brokerage.
Tax-free savings for a person with a disability, growth projection, the SSI $100,000 timeline, ABLE-to-Work room, and state tax breaks.
What converting really costs this year, bracket-fill headroom, IRMAA cliffs, the Social Security tax torpedo, and how your state treats conversions (a few don't tax them at all).
What actually lands in your account, 2026 IRS withholding, FICA, all-51-state + local taxes, and a Traditional-vs-Roth 401(k) comparison nobody else has. Your salary stays private.
Will you owe next April? Project your refund-or-owed from real pay stubs and get exact per-job W-4 numbers to fix it, including 2026's new overtime, tips, and 65+ deductions. It remembers your setup, so the January re-check takes thirty seconds.
Should you refinance? Your true break-even, not the naive one lenders show, the term-reset trap, and the exact rate where a refi starts paying off for how long you'll actually stay.
Are you leaving free employer-match money on the table? The exact % to max out 2026's limits (with catch-ups), the front-loading trap plans without a true-up hide, and what it all becomes by retirement.
Brackets are marginal, the real money hides in the cliffs. See exactly how many 401(k)/403(b)/457 dollars duck you under the Roth IRA income cutoff, the Child Tax Credit phase-out, NIIT, and the Saver's Credit tiers, and what this year's savings compound to by retirement.
You inherited an IRA, now what? Five withdrawal timings run through your tax return for every year of the window: required minimums, bracket spikes, IRMAA cliffs, and the year-10 lump-sum trap.
Will the government actually take a cut? The $15M federal exemption, all 13 state estate taxes (including the New York cliff), the 5 states that tax heirs by relationship, and the income-tax trap most families miss.
Your job pays more than your salary, the 401(k) match, employer HSA money, health premiums, stock, pension, and PTO are real dollars. See what a job is actually worth, then compare two offers side by side (the bigger salary doesn't always win).
Most big-name calculator sites are lead-generation businesses, the calculator is the bait, and your income, savings, and retirement plans are the product. That's why they ask for your email, set trackers, and pass your details to advisors and advertisers.
These tools work differently, and you can verify every claim:
The only measurement on these sites is an anonymous, cookieless page-view counter (because I'm curious if anyone uses these). It can't see anything you type.
Every calculator here is one open, self-contained page, an AI can read the whole thing. Copy this into ChatGPT, Claude, Gemini, whichever you trust:
🔍 Prefer to check it yourself? Open DevTools in your browser (press F12), click the Network tab, then type numbers into any calculator here and watch the list: besides the page loading itself, nothing but the one-time analytics beacon ever appears, no matter what you enter. On a lead-gen calculator site, you'd see your keystrokes feeding tracking calls.
None of these calculators is financial advice, and that's not just a legal fig leaf, there are genuinely good reasons to sit down with a human professional: a complex tax year, an estate to plan, a special-needs family member, or simply wanting someone your spouse can trust if you're not around. We encourage it. But the advice industry has a wide quality range, so it pays to understand the room before you walk into it.
The first thing to know is how the person across the table gets paid. It shapes everything they'll tell you:
About that free steak dinner 🥩, the retirement-seminar invitation in your mailbox is a sales funnel, usually for an annuity. By all means enjoy the steak! But go in knowing your actual numbers, because the pitch is engineered for people who don't: some fear ("the market's about to crash"), some urgency ("this window is closing"), and a product that promises to fix both. If you ask twice what the product costs and still can't get a plain answer, that is the answer.
And remember the business model: confusion is the product. A lot of this industry profits from making your money feel too complicated to manage yourself, because the more confusing it feels, the more necessary their services seem. Most of it is arithmetic. Run your own numbers with the tools above, bring them to the meeting, and ask specific questions. A good advisor will be delighted you came prepared. An annoyed one just told you something useful, too.
What a good first meeting looks like: they ask far more than they tell, nothing gets pitched on day one, fees are disclosed plainly and in writing, and the conversation covers taxes, insurance, and estate basics, not just which investments to buy. Guarantees, countdown clocks, and products you can't explain back to them are your cue to leave.
