Sequence of Returns Risk Calculator

Sequence of returns risk is the danger that poor market returns early in retirement permanently damage a portfolio, even when the long-run average return is perfectly acceptable.

The mechanism is withdrawals meeting losses. In a year the market falls 15%, taking income means selling a larger number of shares at a lower price — and those shares are permanently absent from the recovery that follows. The loss isn’t the 15%. The loss is the shares you no longer own when the market comes back.

This is why the average return over a retirement tells you almost nothing on its own. Two retirees can hold identical portfolios, draw identical income, and experience an identical average return over twenty years — and one runs out a decade before the other, purely because of the order the good and bad years arrived in. Nobody chooses their sequence. You retire on the date you retire.

It is also a risk that concentrates at exactly one moment: the first five to ten years after you stop earning. Before retirement a downturn is an opportunity, because you’re still buying. After the portfolio has grown for a decade, withdrawals are a smaller share of it. In between is the window where a bad start does damage that good later returns cannot undo.

If the damage comes from selling into a decline, the defense is having somewhere else to draw from in the years you would otherwise be selling. That is the entire idea. A reverse mortgage line of credit gives a homeowner aged 62 or over a second source of income that isn’t correlated with the market, and drawing on it in a down year lets the portfolio recover with its shares intact.

The research behind this is not promotional. Coordinated-withdrawal strategies have been studied for over a decade — the work most often cited is by Wade Pfau and by Barry and Stephen Sacks — and the consistent finding is that a buffer asset used specifically in down years improves portfolio survival more than the same money used as a lump sum at the start.

What it buys is time, not wealth. That distinction matters, and it is where most presentations of this strategy go wrong. Run the scenarios above and the coordinated strategy rarely ends with a larger net worth. What it does is fund more years of income before the money runs out — which, if you are eighty-two and still need to eat, is the number that actually matters.

The growing credit line is not a return. A HECM line grows over time whether or not you use it, and that growth is genuinely useful. But on a HECM the unused line and the loan balance compound at the same rate. The line growing is the pricing of a loan you haven’t drawn yet, not interest you’re earning. This calculator shows the loan balance beside the years it bought for exactly that reason.

A strategy that costs something is wrong for some people, and this one is wrong for more people than the reverse-mortgage industry tends to say.

If the house is the inheritance. The loan is repaid from the home. Every year of extra income comes out of what your children receive. For some families that is obviously the right call — the money was needed — but it should be a decision someone made, not a surprise discovered at the estate.

If you might move. A HECM becomes payable when the last borrower leaves the home for more than twelve consecutive months. A move to be near family, or a nursing-home stay that runs past a year, ends the strategy and triggers repayment. Upfront costs are meaningful, so a short horizon rarely justifies them.

If you have other liquid assets. Cash, bonds or a taxable account can serve as the same buffer without a loan attached. The strategy is strongest for people whose wealth is concentrated in the house and a retirement account, which is a common situation but not a universal one.

If your withdrawal rate is already low. Sequence risk is a problem for people drawing a meaningful percentage each year. Draw 2% of a large portfolio and a bad decade is uncomfortable rather than fatal, and the loan buys little.

Every HECM requires independent counseling from a HUD-approved agency before an application can proceed. That session is free, it is not a sales meeting, and for a decision this size it is an hour well spent regardless of what you conclude.
