The bridge strategy: retire now, live on savings, and delay Social Security to 70 so the benefit is permanently 77% larger than claiming at 62. This works out what the bridge costs and whether your portfolio can carry it.

## The trade in one line

You spend a defined, known amount of savings over a defined, known number of years. In exchange you get an inflation-linked income that is larger for life and cannot run out. On a $2,000 full benefit, claiming at 62 pays $1,400 a month and claiming at 70 pays $2,480 — the same person, $1,080 a month apart, forever.

## What the bridge costs

Bridging from 62 to 70 means funding eight years of the benefit you are not taking. At the age-70 amount that is roughly the figure below — and that is the honest price of the strategy.

| Your full benefit (at 67) | Claim at 62 | Claim at 70 | Monthly gain | Approximate 8-year bridge cost |
| --- | --- | --- | --- | --- |
| $1,500 | $1,050 | $1,860 | **$810** | $178,560 |
| $2,000 | $1,400 | $2,480 | **$1,080** | $238,080 |
| $2,500 | $1,750 | $3,100 | **$1,350** | $297,600 |
| $3,000 | $2,100 | $3,720 | **$1,620** | $357,120 |
| $3,500 | $2,450 | $4,340 | **$1,890** | $416,640 |

Bridge cost is the age-70 benefit funded from savings for eight years, ignoring growth on the money — a deliberately conservative way to look at it.

## Why it is usually a good trade

Think of the bridge as buying an annuity. Spending $238,080 of savings to buy $1,080 a month of extra inflation-linked income for life is a payout rate no commercial annuity comes close to matching — and it comes with a government guarantee, an automatic cost-of-living adjustment, and no insurance company credit risk. For the higher earner in a couple it is better still, because the larger benefit also becomes the survivor benefit.

## When the bridge does not work

- **The portfolio is too small.** If eight years of full spending would take the balance below roughly ten years of remaining expenses, the bridge is buying insurance you cannot afford. Run it above and look at what is left.
- **Health is poor.** The trade only pays if you live past the break-even age. See the [break-even calculator](https://savingslast.com/social-security-break-even-calculator/).
- **A bad market arrives at the same time.** Front-loading withdrawals is exactly the sequence-of-returns risk retirees are warned about. The standard defence is to hold the bridge years in cash or short-term bonds rather than in equities, so the withdrawal is not forced from a fallen market.

## The tax bonus nobody mentions

The bridge years are usually the lowest-income years of your life: no salary, no Social Security, no required minimum distributions. That is the ideal window for Roth conversions — moving traditional 401(k) money to Roth at a low bracket, which shrinks the required distributions waiting at 73 and reduces how much of your Social Security becomes taxable later. Many retirees find the tax saving alone justifies the bridge.

## Running it here

Set the balance to your portfolio, the withdrawal to your full monthly spending, and the age to the age you retire. Enter the benefit you will claim in the Social Security box, with the age you will claim it. Savings carry the whole load until that age and only the gap after it. One run shows whether the plan survives both stages.

## Frequently asked questions

**What is a Social Security bridge strategy?**

Retiring before claiming Social Security and living on savings in the meantime, so the benefit can grow by 8% a year in delayed retirement credits. The savings spent are the "bridge" between the retirement date and the claiming date.

**How much does it cost to delay Social Security to 70?**

Roughly the age-70 benefit multiplied by the number of months you delay. Delaying eight years on a $2,480 age-70 benefit costs about $238,000 of savings, and buys about $1,080 a month more, inflation-adjusted, for life.

**Is delaying Social Security better than buying an annuity?**

For most retirees, yes. The implied payout rate on delayed Social Security is higher than commercial inflation-adjusted annuities, it carries a government guarantee rather than an insurer’s, and it automatically raises the survivor benefit for a spouse.

**Where should the bridge money be invested?**

Money you will spend within the next two to three years generally belongs in cash, short-term Treasuries or CDs rather than equities. Front-loading withdrawals into a falling market is the main way this strategy goes wrong, and holding the near-term spending in cash removes that risk.
