About You
Used to determine your Full Retirement Age (FRA).
Find this at ssa.gov/myaccount. Use the SS Claiming Calculator if you need to estimate it.
Total household spending per year, before Social Security.
Your Savings
Withdrawals draw from these accounts in order: Cash → Taxable → Pretax → Roth — the same order used by SmartRetireCalc’s main retirement engine.
Assumptions
The comparison table below always shows all four.
What is the Social Security “bridge”?
If you stop working before you start claiming Social Security, you need income from somewhere in the meantime — usually your own savings. This gap is often called the “bridge” period. The longer you delay claiming, the larger your eventual monthly benefit, but the more you’ll typically need to withdraw from savings while you wait.
Why not just always delay to maximize the monthly check?
A bigger monthly benefit at 70 doesn’t automatically mean more total wealth. If delaying forces you to draw down savings that would otherwise have kept compounding, the “cost” of the bridge years can offset — or even exceed — the extra Social Security income, depending on your account balances, spending needs, and investment returns. See Social Security 62 vs. 67 vs. 70 for the factors that tip the decision each way, with real worked examples.
How does this calculator decide what to recommend?
It runs a year-by-year simulation of your savings (Cash, Taxable, Pretax, Roth) for all three claiming ages — 62, your Full Retirement Age, and 70 — and totals up the lifetime wealth (Social Security received plus whatever savings remain) for each, out to your selected life expectancy. Whichever strategy produces the highest total is recommended — it is not automatically the one that delays the longest.
