Social Security
When you claim Social Security is one of the most consequential decisions in retirement — the gap between claiming at 62 and at 70 can be six figures over a lifetime, and for a couple it also shapes what the survivor lives on. RetireRange models it as a real, adjustable decision rather than a fixed number.
Entering your numbers
Pull your estimates from your statement at ssa.gov and enter, for each person, the projected monthly benefit at:
- Age 62 (earliest, reduced),
- Full Retirement Age (FRA) (your full benefit), and
- Age 70 (maximum).
RetireRange interpolates every age in between. Your FRA depends on your birth year — it’s 67 for anyone born in 1960 or later — and RetireRange looks it up automatically from the birth date you entered.
How claiming age changes your benefit
The choice is permanent, and the swing is large:
| Claim at | Effect on your monthly benefit |
|---|---|
| 62 | Reduced roughly 25–30% below your FRA amount |
| FRA (66–67) |
Your full benefit |
| 70 | Increased roughly 24–32% above FRA (about 8% for each year you delay past FRA) |
There’s no benefit to waiting past 70. Longevity is the trade-off most people know about: delaying pays off the longer you live; claiming early pays off if life is shorter. But it isn’t the only one — what your portfolio does while you wait matters just as much, and that’s the part a benefit-only comparison misses. See below.
What delaying actually costs — and why waiting isn’t always best
Conventional advice says "delay if you can." RetireRange models the decision properly instead of assuming it, because delaying has a real, immediate cost that a benefit-only comparison hides.
Your withdrawal target is total household spending, and Social Security counts toward it — reducing what comes out of your accounts dollar for dollar (see Strategy tab). So during any year you delay, there’s no benefit offsetting your spending and the portfolio carries the entire load.
Example. You spend $8,000/month and would receive $3,000 from Social Security. Claim now and your accounts supply $5,000/month. Delay four years and they supply the full $8,000 — roughly $144,000 of extra withdrawals over those years, plus the growth those dollars would have earned.
That’s the case against waiting. The case for it is still strong: a permanently larger, inflation-adjusted, government-backed check, a bigger benefit protecting the survivor, and less of your plan riding on market returns. Delaying essentially buys longevity insurance using portfolio dollars.
Which side wins depends on your situation — genuinely:
- Portfolio size. A large portfolio absorbs the delay-years drawdown easily, so the bigger lifetime benefit tends to win. A tighter portfolio may not survive four years of unsupported withdrawals — especially in a bad market.
- Sequence risk. Delay years fall in early retirement, when a downturn does the most damage. Larger withdrawals into a falling market are the classic failure pattern — see Understanding your results.
- RMDs and later taxes. This one cuts for delaying, and it’s easy to miss. Spending down Traditional balances during the delay years shrinks the balance subject to RMDs later, which can mean lower forced income, a lower bracket, and less IRMAA exposure in your 70s and 80s. Claiming early preserves those balances — and the larger RMDs that come with them.
- Longevity and survivor needs. The longer you (or your surviving spouse) live, the more the bigger check compounds in your favor.
These pull in different directions, and the balance is specific to your numbers — which is exactly why it’s worth testing rather than assuming. Run it: what happens if I collect early? · let the Optimizer search claiming ages
For couples
- Spousal benefit. Each spouse receives the larger of their own benefit or up to 50% of the other spouse’s FRA benefit. RetireRange applies this automatically — you don’t configure it. (The spousal amount is reduced if claimed before the claimant’s own FRA.)
- Survivor benefit. When one spouse dies, the survivor keeps the larger of the two benefits; the smaller one stops. This is why the higher earner’s claiming age matters so much: delaying locks in a bigger check that can support the survivor for years. RetireRange models the survivor benefit with the real SSA age-graded factor — from 71.5% at age 60 up to the full 100% at the survivor’s full retirement age — paid as the larger of the survivor’s own or the deceased’s benefit.

Social Security and taxes
Up to 85% of your benefit can be subject to federal income tax, depending on your total income (RetireRange uses the IRS Pub 915 formula). Roughly, for a married couple filing jointly:
- Below about $32,000 of combined income (counting half your SS): none of your benefit is taxed.
- $32,000–$44,000: up to 50% becomes taxable.
- Above $44,000: up to 85% becomes taxable.
(Lower thresholds apply to single filers.) At higher retirement incomes, assume 85% of your benefit is taxable. See Taxes.
Important caveats
- Your SSA estimate assumes you keep working until you claim. If you retire earlier, your actual benefit may be lower, because those missing years drop out of your earnings record. Consider trimming your entered estimates to reflect an earlier stop.
- RetireRange doesn’t model future policy changes. It projects your stated benefit forward with inflation (or a Social Security COLA rate you set), and doesn’t attempt to predict legislative changes to the program. It does keep the model up to date with enacted law, though — we maintain tax brackets, IRMAA thresholds, RMD tables, and Social Security parameters as the rules actually change; what it won’t do is guess at reforms that haven’t passed.
