Free tools
Eight interactive tools for the money decisions people actually wrestle with: when to claim Social Security, Roth or Traditional, paying off the house or investing, and more. Every one runs entirely in your browser, with no signup and no email gate, and nothing you enter is sent or stored.

Should you claim at 62, 67, or 70?
Your monthly benefit at every claiming age and the breakeven between 62 and 70, including what most breakeven tools skip: credit for what early checks could earn in the meantime.
Which leaves more after tax?
Holds your take-home cost constant so the Traditional deduction gets its full credit, then shows which path wins under your own current and future tax rates.
Where should a child's money go?
Puts the same contributions into all three accounts and compares what's left after federal tax for college, a first home, or retirement.
How long will your money last?
Savings, spending, and returns in; longevity out. Includes something most calculators skip: how the order of your returns, not just the average, changes the answer.
How much could your savings grow?
Age, current balance, and yearly contribution in; a year-by-year illustration of your retirement balance out. A clean look at what steady saving does over decades.
Extra cash to the loan or the market?
Compares ending wealth, years to debt-free, and interest saved when the same extra dollars go toward the mortgage or into investments.
How much house fits your budget?
Starts from the 28/36 rule, then shows how the affordable price moves as your income, debts, rate, and down payment change.
How much coverage would your family need?
Adds up debts, income replacement, and future expenses to estimate the coverage that would let your family carry on without your paycheck.
They don't collect any. Every tool on this page runs its math in your browser the moment you move a slider. Nothing you enter is submitted, stored, or tracked, and there is no account to create. Each page also states its assumptions and what the math deliberately leaves out.
Most financial calculators online either oversimplify or exist to capture your email. These are built the way I'd want to see the math myself: assumptions out in the open, the common shortcuts corrected, and the limits of each model stated plainly. If they help you think more clearly about a decision, they've done their job.
Yes. There's no signup, no email gate, and no trial period. They're educational tools published as part of this site. If a calculator raises a question about your own situation, that's what a first call is for, but the tools themselves come with no strings attached.
No. Every calculation happens in your browser as you move the sliders. Nothing you type or select is transmitted, saved, or seen by anyone, including me. Close the tab and it's gone. That's a deliberate design choice, not a technical accident.
Treat them as a starting point, not an answer. Each tool simplifies on purpose, models federal taxes at most, and depends on assumptions you choose. They're built to show how a decision behaves, not to replace advice from your advisor and tax professional, who can see your whole picture.
Almost always. Everything is handled virtually, so where you live is rarely a barrier. The only exception is a handful of states where I'm not registered yet, and if that's you, I'll tell you on our first call.
A calculator gives you a number. These explain what the number is telling you.
Two retirees, same average return, different outcomes. Why the early years count double.
Paying some tax now to skip more later: the mechanism, the window, and the side effects.
Morningstar keeps finding that investors trail the very funds they own. Where the gap comes from, and what closes it.
A calculator can show you how a decision behaves. It can't see your taxes, your family, or the rest of your balance sheet. A short call can.
