Roth IRA 5-Year Rule Calculator

The single most common mistake with Roth accounts is treating "the five-year rule" as one thing. There are two, they measure different periods, and they control different outcomes.

The first is a single clock per person. It starts on 1 January of the tax year for which you made your first ever Roth IRA contribution, and it never restarts. Open a second Roth twenty years later and it inherits the original clock, because all your Roth IRAs are treated as one for this test. What this rule controls is whether earnings come out tax-free.

The second is a separate clock for every conversion you make. It exists for one purpose: to stop people using a conversion to sidestep the 10% early-distribution penalty. Without it, someone under 59½ could convert from a traditional IRA and withdraw immediately, escaping a penalty that would have applied to a direct withdrawal. So each converted amount must sit for five years before it can come out penalty-free.

The second rule stops mattering entirely at 59½, because the penalty it polices no longer exists. The first rule keeps mattering at any age — a 70-year-old who opened their first Roth three years ago still has taxable earnings.

Roth distributions come out in a fixed statutory order that happens to be the most favourable one possible: direct contributions first, then conversions oldest first, then earnings last.

This is why the rules bite far less often than the anxiety around them suggests. Your own contributions are always available, tax-free and penalty-free, at any age and regardless of either five-year rule — you already paid tax on that money and the code does not tax it twice. For most people with a long contribution history, a moderate withdrawal never gets past the first layer.

It is also the entire mechanism behind a Roth conversion ladder. Convert an amount each year, wait five years, and then live on seasoned conversions that carry neither tax nor penalty, while the earnings sit untouched at the bottom of the stack. The ladder works precisely because the ordering rules guarantee you reach the good layers first.

A contribution made before the April filing deadline can be designated for the previous tax year, and the Rule 1 clock then starts on 1 January of that earlier year. A first Roth contribution made in April 2026 for tax year 2025 is treated as five years old on 1 January 2030 rather than 2031. That is a free year for the cost of ticking a box, and it is the single easiest thing to get right when opening a first Roth.

Roth 401(k) accounts run their own separate clock, which does not carry over to a Roth IRA. Rolling a Roth 401(k) into a Roth IRA adopts the IRA's clock — helpful if the IRA is older, harmful if it is not, and a reason to open a Roth IRA with a small contribution early even if you do not intend to fund it properly for years.

The first-time homebuyer exception is narrower than it sounds. It waives the penalty on up to $10,000 of earnings over a lifetime, but it does not waive the income tax unless the five-year rule is also satisfied. And "first-time" means not having owned a principal residence in the previous two years, which is more generous than the phrase suggests.

Finally, inherited Roth IRAs follow different rules again. The deceased's five-year clock carries over to the beneficiary, so a Roth inherited from someone who opened it decades ago is immediately qualified, while one opened two years before death is not.
