percent How the math works

We use the standard amortization, compound-interest and present-value formulas published by the Consumer Financial Protection Bureau and the Federal Reserve. The methodology block below shows every variable and rounding step we apply, so the answer is never a black box.

Every calculation happens in your browser with JavaScript — your income, balances, and loan numbers are never sent to our servers, logged, or shared. Close the tab and the inputs vanish. No sign-up, no tracking pixels on the form, no spreadsheet emailed to you later.

lightbulb Pro tip

Save the URL after you calculate — your inputs aren't stored, so write down the headline number plus the breakdown. Then come back and edit one variable at a time (down payment, rate, term) to see exactly which lever moves your monthly figure the most. That's where the real planning happens.

Interpretation guide

Why a Roth IRA is powerful:

FeatureBenefit
Tax-free withdrawalsQualified withdrawals in retirement are not taxed
No RMDsNo required minimum distributions for the owner
Contribution accessYou can withdraw your contributions anytime
Tax diversificationBalances pre-tax accounts in retirement

Formula & methodology

Formula: FV = sum of each year's contribution x (1 + r)^(years remaining)

A Roth IRA is funded with after-tax dollars, so qualified growth and withdrawals are completely tax-free. The calculator compounds each annual contribution to retirement age at your assumed return. Because no tax is owed on the back end, a Roth is especially valuable if you expect to be in a similar or higher tax bracket later, or want decades of untaxed compounding.

Frequently asked questions

What is the 2026 Roth IRA contribution limit?
$7,000 if you're under 50, or $8,000 with the catch-up at 50+, subject to income phaseouts.
Are Roth IRA withdrawals taxed?
Qualified withdrawals — after age 59 1/2 and a 5-year holding period — are entirely tax-free, including all growth.
Can high earners contribute to a Roth IRA?
Direct contributions phase out at higher incomes, but a 'backdoor' Roth conversion is a common workaround. Check current MAGI limits.
Roth IRA vs traditional IRA — which is better?
Roth if you expect higher future taxes or want tax-free growth and no RMDs; traditional if you want a deduction now and expect a lower bracket later.
Can I withdraw my Roth contributions early?
Yes — your own contributions (not earnings) can be withdrawn anytime without tax or penalty.
