Social Security Bridge Calculator — Delay to 70, Bridge With a MYGA
TL;DR: Every year you delay claiming Social Security past full retirement age, your monthly benefit grows 8% (guaranteed by the government). Delaying from 62 to 70 increases benefits roughly 76%. The challenge: how do you live for those 8 years? Build a MYGA or SPIA bridge sized to the exact gap.
How this calculator works
The calculator solves the present value of an annuity due:
PV = PMT × (1 - (1+i)^-n) / i
Where:
- PMT = monthly bridge income you want (typically your target retirement spending or your projected age-70 SS benefit)
- i = monthly MYGA rate (annual / 12)
- n = number of months until SS starts (e.g., age 62 to 70 = 96 months)
This gives the exact MYGA principal needed to fund monthly withdrawals until SS kicks in, assuming you deplete the MYGA to zero at the SS start date.
The lifetime SS gain compares the cumulative SS dollars from claiming at 70 vs 62, projected to age 90. The crossover point (where claiming at 70 pulls ahead of claiming at 62) is typically age 80-82.
What the result means
The big number is the MYGA principal you need TODAY to fund living expenses until age 70 while delaying SS. If you have this much in liquid savings to commit to a 5-8 year MYGA, the bridge math works.
The years to bridge shows how long you need to fund out-of-pocket. From age 62 = 8 years. From age 65 = 5 years. From age 67 (full retirement age) = 3 years.
The lifetime SS gain shows how much extra Social Security you'll collect (gross, not present-value) by delaying. For most people delaying from 62 to 70, this is $250K-$500K over a 20-year retirement.
The math typically pays for someone in good health: if you live past 82, delaying wins. If family history points to mid-70s mortality, claim earlier.
When MYGA wins / when the alternative wins
Bridging to 70 wins when: you're in good health (longevity past 82 expected), spouse will get the survivor benefit at the higher rate, you can self-fund 5-8 years from MYGA + savings.
Claiming at 62 wins when: family longevity is short (mid-70s), you need the income now, or you're divorced/widowed and want the lower lifetime payment to avoid spend-down issues.
Claiming at full retirement age (66-67) wins when: you can afford to wait that long but need income before 70, or your spouse is significantly younger and will outlive you (your higher delayed benefit becomes their survivor benefit).
Worked example
Scenario: 62-year-old in California, $2,100/mo SS at 62 vs $3,700/mo at 70. Wants to maintain $3,700/mo income during the bridge so retirement spending stays constant.
- Bridge years: 8
- Bridge target: $3,700/mo
- MYGA rate: 5.40%
MYGA needed today: approximately $290,000.
From age 62 to 70, she draws $3,700/mo from the MYGA. At 70, the MYGA is essentially depleted, and SS takes over at $3,700/mo for life.
Lifetime SS gain to age 90: ($3,700 - $2,100) × 12 × 20 = $384,000 in extra Social Security dollars vs claiming at 62. Crossover age: ~80.
Net: she invested $290K, got $384K back in extra SS over 20 years, AND her surviving spouse gets the higher benefit.
Common mistakes
- Not accounting for inflation in the bridge target. $3,700 today buys less in 8 years. Add 2-3% per year of cushion or use COLA-adjusted SPIA for the bridge.
- Forgetting the spousal/survivor benefit. The higher earner delaying to 70 also raises the surviving spouse's benefit. This is huge for couples.
- Bridging with stocks. Sequence-of-returns risk — a bad year right after retirement can wipe the bridge. MYGA/SPIA removes this risk.
- Underestimating IRMAA. Drawing down IRA/401(k) for bridge income can push you into IRMAA Medicare surcharges. Use Roth or taxable MYGA when possible.
- Bridging too aggressively. If you've got enough to delay to 67 but not 70, take 67. Partial delay beats no delay.

FAQ
Q: Is the 8%/yr SS increase guaranteed?
A: Yes, by federal law. Delayed Retirement Credits add 2/3 of 1% per month between full retirement age (66-67) and age 70. That's 8% annualized, simple.
Q: Can I use my IRA instead of a MYGA for the bridge?
A: Yes, but watch for sequence risk if invested in stocks, and watch IRMAA / bracket creep on the withdrawals. A MYGA inside an IRA gets you the same bridge with no market risk.
Q: What if I die during the bridge years?
A: MYGA balance passes to beneficiaries with no surrender charge. SS bridge stops, but spouse gets survivor benefit (claimed at your delayed amount if you've reached FRA).
Q: Should both spouses delay?
A: Usually no — common strategy is higher earner delays to 70, lower earner claims at 62-67. Survivor gets the larger benefit; while both alive, you have some income flowing.
Q: What if SS gets cut?
A: Even a 20% across-the-board cut in 2034 still leaves delayers ahead vs claimers, because the delay multiplier (8%/yr) applies to whatever the actual benefit is at claim time.
Q: Why is age 80-82 the break-even?
A: Below 80, more years of smaller-checks-from-62 win. Above 80, fewer-years-of-bigger-checks-from-70 win. Life expectancy at 65 is roughly 82-85, so most retirees come out ahead delaying.
Q: Does this work for SSDI or survivor benefits?
A: Different rules apply — the 8% delay credit is specifically for retirement benefits. SSDI converts to retirement at FRA automatically; survivor benefits have their own claiming windows.
