Bond Tent Calculator
Build a rising equity glidepath ("bond tent") that increases bond allocation 5 years before retirement, then gradually lowers it over the first 5-10 years of retirement. Defends against sequence-of-returns risk in the fragile decade around your retirement date.

What Is a Bond Tent Glidepath?
The bond tent is a rising-then-falling equity glidepath designed by retirement researcher Michael Kitces and Wade Pfau (PhD, Professor of Retirement Income at The American College). Unlike traditional declining-equity glidepaths (e.g. "age in bonds"), the bond tent temporarily raises bonds in the 5-10 years before retirement, peaks at the retirement date, then declines bond allocation back down over the first 5-15 years of retirement — effectively re-rising equity exposure as you age. The shape on a chart resembles a tent or pyramid. The strategy was published in Kitces and Pfau's 2014 Journal of Financial Planning paper "Reducing Retirement Risk with a Rising Equity Glidepath" which demonstrated lower portfolio failure rates than static or declining-equity approaches in the SAFEMAX failure analysis.
Why It Works — Sequence-of-Returns Risk
The 10-year window around retirement (5 years before to 5 years after) is the "fragile decade" where portfolio sequence matters most. A 30% market crash in year one of retirement permanently reduces sustainable withdrawals — even if the market fully recovers, the dollars sold at the bottom are gone. The bond tent reduces equity exposure precisely when sequence risk is highest, then rebuilds equity exposure as the retirement progresses and the portfolio is no longer in its most vulnerable phase. Per Federal Reserve historical return data, a U.S. retiree who began retirement in 1966 or 2000 with a static 60/40 portfolio and 4% withdrawal saw a meaningfully worse failure rate than one who started in 1985 or 2010 — sequence risk is the bigger driver of failure than average returns over a 30-year horizon. The bond tent doesn't change average returns much; it just smooths out the worst sequences.
How to Implement the Bond Tent
Calculate the annual rebalancing step required to move from your current allocation to the peak bond allocation at retirement (typically 50% bonds), then plan the reverse glidepath back down to a long-term target (typically 30% bonds). Example: a 55-year-old at 80/20 planning to retire at 65 with a peak of 50/50: shift 3 percentage points per year toward bonds over 10 years. Then from 65 to 75, shift 2 points per year back toward stocks until reaching 70/30. Implementation through new contributions (not selling) reduces tax drag — direct new 401(k) dollars to bond funds while equity holdings continue compounding. In taxable accounts, use the rebalancing band approach to defer capital gains. For more aggressive sequence-risk protection, pair the bond tent with a 1-2 year cash bucket of expenses to avoid selling either bonds or stocks in a bad year.
Bond Tent vs Other Glidepath Strategies
The traditional declining glidepath (target-date funds, age-in-bonds rule) keeps lowering equity throughout retirement — safe but leaves return on the table at older ages when behavioral risk has largely passed. The static glidepath (60/40 forever) is simplest but vulnerable in the fragile decade. The rising equity glidepath (Kitces/Pfau) outperforms in worst-case scenarios because it has the lowest equity exposure at the most vulnerable moment. The bond tent variant peaks at retirement rather than continuing to rise, which captures the sequence protection without going overweight equity at advanced ages where reduced cognitive ability or longer-term care concerns argue for more conservative allocations.

Frequently Asked Questions
What is a bond tent glidepath?
A retirement glidepath that raises bond allocation 5-10 years before retirement, peaks at the retirement date (usually around 50% bonds), then gradually lowers bond allocation over the next 5-15 years of retirement. The shape resembles a tent. Designed by Kitces and Pfau to defend against sequence-of-returns risk in the fragile decade around retirement.
Why does the bond tent rise equity after retirement?
Sequence-of-returns risk is highest in the 5 years before and 5 years after retirement. After that window, the portfolio is more resilient because either the market recovered or the portfolio has shrunk enough that withdrawal dollars do less damage. Rising equity in late retirement also defends against longevity risk and helps a portfolio survive past 30 years.
How much should I shift to bonds at retirement?
Common bond tent peaks are 40-60% bonds depending on risk tolerance. Pfau's research found 50% bonds at retirement minimized failure rates across historical periods. Higher peaks (60%+) further protect against severe early-retirement crashes but reduce long-term growth potential.
When should I start the climb to peak bonds?
Five years before retirement is the most common starting point. Starting earlier (10 years before) wastes equity growth in years that are still relatively safe. Starting later (3 years before) doesn't give enough runway to build the bond cushion. Five years is the sweet spot in Kitces' research.
Does this work with target-date funds?
No, target-date funds use declining glidepaths that never reverse. To implement a bond tent, you need to manage your own allocation or use a custom managed account. Some retirement-focused robo-advisors now offer rising-equity glidepath options, but most off-the-shelf TDFs do not.
What is the difference between a bond tent and a bond ladder?
A bond tent is an asset allocation strategy — it shifts the stock/bond percentage in your portfolio. A bond ladder is a security selection strategy — buying individual bonds with staggered maturities to lock in known cash flows. The two are complementary: implement a bond tent at the portfolio level, and use a bond ladder for the bond portion to lock in specific maturity-year cash flows.
