Retire With an Age Gap: 3‑Phase Plan

Why You Need This Checklist

What happens when you and your spouse want to retire together — but you're 15 years apart in age? Most retirement calculators assume everyone is roughly the same age, retires at the same time, and lives the same number of years. But your life doesn't work that way, and your retirement plan shouldn't pretend it does.

Here's the uncomfortable truth: a 15-year age gap means your retirement could span 40 years. That's four decades of shifting income, changing Social Security benefits, and a portfolio that has to survive three completely different financial phases. If you plan this wrong — if you treat it like a standard 25-year retirement — you could run out of money while your younger spouse still has 15 or 20 years left to live. That's not a small miscalculation. That's a catastrophic one.

Imagine instead what it feels like to retire together with total clarity. You know exactly how much you need on day one. You know which dollars are earmarked for which phase. You know what Social Security covers, when it kicks in for each spouse, and precisely how much your portfolio has to fill the gap at every stage. That confidence — knowing the plan accounts for all 40 years — is what lets both of you actually enjoy retirement instead of quietly worrying about whether the money will last.

Erin Moriarity of Erin Talks Money built exactly this plan on camera, walking through a real couple with a $200,000 combined income, a 15-year age gap, and a 40-year retirement horizon. She broke the retirement into three distinct phases — the bridge years, the joint retirement years, and the survivor years — and calculated how much each bucket needs to hold on day one, what rate of return each bucket targets, and how Social Security income shifts across all three phases. The result: a specific, grounded dollar figure with a 20% planning buffer built in.

This checklist captures every step of that framework so you can apply it to your own numbers. You'll calculate your actual take-home spending baseline, project both spouses' Social Security benefits and claiming ages, define your three retirement phases with their durations and income targets, size each bucket using a real rate of return, and arrive at a total day-one portfolio target — complete with a buffer for market volatility and unexpected costs.
