Most retirement calculators ask three questions and draw a line. We model what actually happens to your money: year by year, dollar by dollar, after taxes.
Every factor that affects how much you can actually spend, not just how much you've saved.
We compute your tax bill year by year using actual progressive brackets, not a flat "25% tax rate" guess. Every withdrawal and income source hits the right bracket.
The gap between employer coverage and Medicare (ages 55–65) is the most expensive surprise in early retirement. We model ACA premiums, subsidies based on your income, IRMAA surcharges, and out-of-pocket costs.
Your Social Security benefit is factored into your projection at your expected claiming age, including how much of it gets taxed (up to 85%) and how it interacts with your other income sources.
$1M in a traditional IRA is not the same as $1M in a Roth. We track traditional, Roth, and taxable accounts separately, because each has different tax treatment that changes how much is actually yours to spend.
Salary, rental income, pensions, part-time work, Social Security. Each source has different tax treatment. We layer them correctly so your brackets are accurate.
$80K/year today won't buy the same in 20 years. Every number in your projection is in today's dollars so you can compare apples to apples across your timeline.
At 73, the IRS forces withdrawals from tax-deferred accounts. We model RMDs using IRS life expectancy tables and factor the tax impact into your plan.
Taxable accounts generate annual tax drag from dividends and realized gains. We track cost basis and apply the correct rates: long-term, short-term, and qualified dividends.
For married couples filing jointly, we model both spouses' accounts, RMDs, Social Security benefits, and what happens financially when one spouse passes.
The amount you can spend every year (after taxes, after healthcare) without running out. Not a guess. A number backed by a year-by-year projection.
How much you'd have left if you retire at 60 vs. 63, downshift to part-time, or take a sabbatical, or when you'd run out if spending is too high. Model as many scenarios as you want; each one answers "can I afford this?"
Lumifin runs withdrawal-order and Roth conversion combinations against your real numbers and shows each one's ending balance, lifetime taxes, and healthcare savings, so you choose from strategies you can compare, not guesses.
Step-by-step tutorials walk you through the strategy behind the numbers (withdrawal order, Roth conversions, the ACA cliff) so you understand what drives your plan, not just what it says.
Get full Lumifin app access for $199/yr and model every retirement decision yourself: withdrawal sequencing, Roth conversions, ACA strategy, as many scenarios as you want. Course tutorials that walk you through the strategy are included.
