How Much Do You Need to Retire as an Immigrant?

Your retirement number depends on where you plan to spend it more than almost any other factor — a target sized for a US retirement can be far more than you need if you eventually retire in India, and calculating just one number without deciding which country it’s for is the most common mistake in this kind of planning.

The two-number problem

Most retirement calculators assume you’ll retire in the same country you’re saving in, with a cost of living that doesn’t change. That assumption doesn’t hold for many H1B and green-card-track immigrants, who genuinely don’t know yet whether they’ll retire in the US, move back to India, or split time between both. Rather than guessing, calculate two numbers:

1. A US-retirement number, using your expected US cost of living and a standard withdrawal-rate calculation.
2. An India-retirement number, adjusted for a lower cost of living — our cost-of-living calculator covers the specific comparison in detail.

If you’re still deciding, save toward the higher of the two. A US-sized nest egg comfortably covers a lower-cost retirement elsewhere; the reverse leaves you short.

The Social Security gap most immigrants don’t know about

US Social Security eligibility requires 40 work credits — approximately 10 years of US employment with Social Security tax withheld — regardless of citizenship or visa status at the time you claim benefits. That part is the same for everyone.

What’s different: the US has totalization agreements with roughly 30 countries that let partial work credits from both countries count toward eligibility in either one. India is not on that list. A worker who splits a career between the US and, say, Germany, can combine partial credits from both countries to qualify. A worker who splits a career between the US and India cannot — each country’s system stands alone.

Practically, this means: if you’re not confident you’ll hit 10 full years of US employment, don’t build your retirement plan assuming a Social Security benefit will supplement it. Your 401(k)/IRA balance has to be closer to self-sufficient than the standard American retirement-planning assumption, which typically treats Social Security as covering a meaningful floor of guaranteed income.

A worked example

Anand is 34, earning $130,000, with $85,000 already saved across a 401(k) and IRA. He’s undecided on retiring in the US or India, and plans to keep working until 62.

US-retirement number: He estimates he’d want $90,000/year in today’s dollars to maintain his current lifestyle in the US. Using a 4% withdrawal rate: $90,000 ÷ 0.04 = $2,250,000 target.

India-retirement number: A comparable lifestyle in a Tier 1 Indian city might cost meaningfully less — the exact ratio depends heavily on city and lifestyle, which is why this deserves its own calculation rather than a rule of thumb. Say his estimate comes out to $45,000/year equivalent. At the same 4% rate: $45,000 ÷ 0.04 = $1,125,000 target — half the US number.

Since he’s undecided, he plans toward the $2,250,000 US number. Contributing $2,000/month at a 7% expected return from his current $85,000 base, the compound interest calculator below shows where that trajectory lands by 62.

If his projection lands short of $2,250,000 but comfortably clears $1,125,000, he has real information: he’s on pace for an India retirement but would need to increase contributions, work longer, or accept a leaner US budget to hit the higher target.

What’s structurally different for immigrants, beyond the two-country math

• 10-year work history isn’t guaranteed the way it is for a US-born saver. A layoff, a status change, or a return home at year 7 can permanently close the door on Social Security eligibility in a way that doesn’t apply to someone who was always going to work in the US regardless.
• Currency and inflation risk compound if the retirement destination changes. A target set in dollars and later spent in rupees (or the reverse) is exposed to exchange-rate movement over decades, on top of ordinary inflation — a reason to revisit the calculation periodically rather than setting it once at 30 and assuming it holds.
• RMD rules still apply even if you’ve left the country. Once you turn 73, required minimum distributions from traditional 401(k)/IRA accounts apply whether you’re a US resident or a nonresident alien living abroad — see our RMD basics guide for the calculation.
