Bond and TIPS ladders: building a paycheque that can't fall

The strategies so far have all shared one anxiety: they draw income from assets whose value bounces around, so they spend their cleverness managing that bounce. A bond ladder asks a heretical question — what if your near-term income simply didn’t bounce at all? It’s the eighth stop on our withdrawal tour, and it marks the shift from managing market risk to sidestepping it. Instead of a withdrawal rate, you build a machine that hands you a known sum on a known date, and the market’s daily mood becomes none of your business.

What a ladder is

A bond ladder is a set of individual bonds bought so that one matures in each year you’ll need money. Buy a bond maturing in 2027, another in 2028, another in 2029, and so on out as far as you care to build. Each year, one “rung” matures, handing you its full face value in cash — that’s your income for the year. You spend it, and next year the following rung matures on cue.

The critical phrase is held to maturity. A bond’s market price wobbles day to day with interest rates, but if you hold it until it matures, none of that matters: you get exactly the face value the issuer promised, on exactly the date promised, regardless of what prices did in between. You’ve swapped “sell some of a volatile portfolio and hope” for “collect a predetermined cheque.” The wobble still happens; you’ve simply arranged never to be a forced seller during it, so it can’t touch you.

The inflation problem, and TIPS

Ordinary bonds have one serious flaw for a retiree: they pay back nominal pounds or dollars. A bond promising £40,000 in fifteen years will hand over £40,000 that, after fifteen years of inflation, buys a good deal less than £40,000 does today. Build a long ladder of ordinary bonds and inflation quietly erodes the real value of your future rungs.

The fix is inflation-linked bonds — in the US, Treasury Inflation-Protected Securities, or TIPS; in the UK, index-linked gilts. Their principal rises with inflation, so a TIPS ladder delivers a stream of income with guaranteed purchasing power. A 30-rung TIPS ladder is about as close as a private individual can get to a homemade, inflation-proof pension: a known real income every year for three decades, backed by the government, with market risk engineered out entirely. For funding essential spending — the costs that must be covered no matter what markets do — it is arguably the safest instrument available to an ordinary retiree.

Strengths: certainty you can build yourself

The great virtue is right there in the description: certainty. A ladder converts an uncertain withdrawal problem into a known cash-flow schedule. Sequence-of-returns risk — the monster stalking every percentage-based strategy — essentially vanishes for the laddered portion, because you are never selling anything into a downturn; you’re waiting for scheduled maturities. There’s no withdrawal rate to agonise over, no annual recalculation, no guessing. And unlike an annuity (which we’ll meet next), you keep full control of the assets: a ladder is just bonds you own, so any unspent rungs pass to your heirs, and you can dismantle it if your plans change.

For the safety-first-minded, it’s the purest expression of matching your assets to your liabilities — you have a spending need in 2035, so you own a bond that pays out in 2035. No hoping, just holding.

Weaknesses: the price of certainty

Certainty is never free, and the ladder’s costs are real. First, lower expected returns: bonds, especially inflation-linked ones, historically return far less than stocks, so a fully-laddered retirement will likely leave you with much less growth — and a smaller final estate — than a stock-heavy portfolio would have. You’re paying for safety in foregone upside.

Second, it can be expensive or awkward to fund: locking in thirty years of real income up front requires a large pot, precisely because the low-returning assets do little of the heavy lifting themselves. Building and maintaining a ladder of individual bonds also takes some effort and know-how, though laddered bond funds and off-the-shelf TIPS-ladder tools have made it far more approachable than it once was.

Third, and subtly, longevity risk isn’t fully solved: a 30-year ladder is brilliant until year 31. If you outlive the ladder, the income simply stops. Unlike an annuity, a ladder doesn’t pay “for life” — it pays “for as long as you built it.” That’s why ladders are often paired with either a longevity annuity for the far tail or a growth portfolio meant to be tapped only if you live long enough to need it.

Who it suits, and how it fits

Bond and TIPS ladders suit the retiree who wants to guarantee their essential spending and is content to accept lower growth in exchange for that guarantee — someone for whom “will my income survive?” matters far more than “could my income have been higher?” They’re the backbone of the flooring approach we’ve been building toward: cover the must-pay costs with laddered, guaranteed income, and let a separate growth portfolio handle the discretionary extras and the upside. In that role they’re less a rival to the percentage strategies than a complement — the safe floor beneath a riskier ceiling.

Strata doesn’t build ladders for you — that’s a matter of buying the actual bonds at your broker — but it’s exactly the tool for keeping track of one. A ladder is a collection of individual holdings with different maturities and cash flows, and a reconciled ledger you built yourself is how you see the whole schedule in one place: which rung matures when, how much real income each year holds, and how the laddered floor sits alongside your growth accounts in your total net worth. Tracking a ladder across a spreadsheet and three brokerage logins is exactly the mess that manual-but-unified record-keeping exists to fix.

Next we look at the strategy that does guarantee income for life, by handing the longevity problem to an insurance company — income annuities and the safety-first floor. Or build your portfolio and start tracking a ladder as the accounts that hold it.
