ZBee

ZBee — estimate your safe yearly spend in retirement, after tax, right on your iPhone or iPad. How much can you safely spend each year in retirement? ZBee gives you a quick, private estimate — on your device, in seconds. Enter your savings, your age, and when you plan to retire, and ZBee estimates the most you can safely spend each year, stress-tested across 600 simulated market histories. No account, no sign-up, nothing to configure. After tax, not before: Most calculators hand you a withdrawal figure and leave the tax bill to you. ZBee works out federal income tax on every year of every simulation — so the number you see is money to actually live on. • It knows the difference between a 401(k), a Roth, and a brokerage account, and taxes each one as you draw it down. • It works out how much of your Social Security is taxable, using the provisional-income rule. • It counts the 10% penalty on retirement money drawn before 59 — so an early retirement gets an honest answer. See the whole picture, not just a number: • A live estimate that updates as you adjust any input, and a risk setting for how cautious you want to be. • Could you afford a specific number? Enter what you want to spend and see how often it lasted. • Your savings, projected. Watch your money grow until you retire and draw down after — charted through a poor market, not a flattering average one. • What waiting buys you. Compare your estimate side by side at earlier and later retirement ages. • When to claim Social Security. See what claiming at 62, 67, or 70 does to your safe spend, each age calculated against your own plan. • Married? Add your spouse's age and Social Security benefit, and ZBee counts both benefits, including the spousal amount when it is larger. • How your spending would flex. Real plans don't spend a fixed number forever — see how much you'd trim after bad markets, and how much more you could spend after good ones. • Still saving? Add what you put away each year and watch it compound into the answer. • Your estimate over time. ZBee remembers each day's estimate on your device, so you can see which way your number is moving. Private by design: • Everything runs entirely on your device. Nothing you enter is sent to us or anyone else. • No account. No tracking. No analytics. The app makes no network requests at all. • No permissions needed. The only prompt you will ever see is if you choose to turn on an optional check-in reminder. ZBee is a measurement and planning tool, not financial advice. Estimates are hypothetical, will not match actual results, and are for U.S. investors. The app estimates federal tax only — it does not model state income tax, Medicare surcharges, or required minimum distributions, and explains what it leaves out in the app.
