What will your income be when you retire?
Where does retirement income come from?
Retirement income doesn't come from one place. For most Americans it comes from a mix of 401(k) and IRA withdrawals, Social Security, and sometimes real estate or brokerage income. The mix looks different for everyone, and knowing where yours will come from is the first step to figuring out what your monthly income will actually be.
For most households, 401(k) withdrawals and Social Security together account for over 70% of retirement income. The standard rule of thumb for 401(k) withdrawals is the 4% rule: in your first year of retirement, withdraw 4% of your total portfolio, then adjust for inflation each year. The rule comes from the Trinity Study, which found that this approach gives a portfolio a high probability of lasting 30 years.
Social Security is the one source you can grow just by waiting. Every year you delay claiming, up to age 70, increases your monthly benefit for life. The difference between claiming at 62 and claiming at 70 can be more than 75% in monthly income. For a married couple, the higher earner's claiming age also determines the survivor benefit, so it's one of the biggest financial decisions a household makes.
How much income will your savings generate?
The 4% rule gives you a starting estimate. Multiply your total portfolio by 4% to get your first-year withdrawal, then divide by 12 for a monthly figure. A $500,000 portfolio generates roughly $1,667 per month. A $1,000,000 portfolio generates roughly $3,333 per month. Add your Social Security benefit at your chosen claiming age and you have a baseline monthly income estimate.
The 4% rule was designed for a 30-year retirement. If you retire early, at 55 or 60, a more conservative withdrawal rate of 3 to 3.5% provides more protection. If you retire later, a higher rate may be sustainable. Your actual withdrawal rate should account for your age at retirement, your expected expenses, your other income sources, and how you'd handle a bad market in your first few years of retirement.
Healthcare is the expense most people underestimate. Fidelity estimates a 65-year-old couple retiring today will need around $330,000 for healthcare over the course of retirement, and that figure doesn't include long-term care. Healthcare costs also tend to rise faster than general inflation, so a fixed income buys less of it every year.
Why the age you claim Social Security matters
Social Security benefits are calculated based on your 35 highest-earning years, adjusted for inflation. Your Full Retirement Age (FRA) is 67 if you were born in 1960 or later. Claiming before FRA permanently reduces your benefit. Waiting past FRA permanently increases it by 8% per year up to age 70.
The break-even age is the point where the total lifetime benefit of waiting surpasses the total benefit of claiming early. It typically falls around age 78 for the 62 versus 67 comparison, and around 82 for 67 versus 70. If you expect to live past those ages, waiting pays off in total lifetime income.
For married couples, the decision is more complex. The lower-earning spouse can claim a spousal benefit equal to 50% of the higher earner's benefit if that exceeds their own. The higher earner delaying to 70 also maximizes the survivor benefit: if one spouse dies, the surviving spouse keeps the higher of the two benefits for life. Because of this, it rarely makes sense for both spouses to claim at the same age.
When should I claim Social Security?
The right age depends on your health, your other income sources, and whether you're married. You can claim as early as 62, but your benefit is permanently reduced to about 70% of your full benefit if your Full Retirement Age is 67. Waiting past your FRA increases your benefit by 8% per year up to age 70, where it maxes out at roughly 124% of your full benefit. The break-even age, where the total lifetime benefit of waiting surpasses the total benefit of claiming early, is typically around 78 for the 62 vs 67 comparison. If you're in good health and expect to live into your 80s, delaying generally makes financial sense.
What is the Social Security break-even age?
The break-even age is the point where your total lifetime Social Security income from waiting equals what you would have received by claiming earlier. For the 62 versus 67 comparison it's typically around age 78. For 67 versus 70 it's around 82. If you live past your break-even age, the higher monthly benefit from waiting means you come out ahead in total lifetime income. If you die before it, claiming earlier would have paid more overall.
How does Social Security work for married couples?
Married couples have a few options that can increase total lifetime household benefits. A lower-earning spouse can claim a spousal benefit equal to 50% of the higher earner's full benefit, if that amount is more than their own earned benefit. When one spouse dies, the surviving spouse keeps the higher of the two benefits for life. This means the higher earner's claiming age affects both people. Delaying to 70 not only increases that person's monthly check but also maximizes the survivor benefit, which matters a lot if one spouse outlives the other by many years.
How much income will you need in retirement?
A common rule of thumb is that you'll need 70 to 80% of your pre-retirement income to maintain your standard of living. Some expenses go away, like commuting, work clothes, and retirement savings contributions, but others go up, particularly healthcare and leisure. Treat the guideline as a starting point. Your actual number depends on when you retire, where you live, whether you carry a mortgage into retirement, and what kind of retirement you want.
A more useful exercise is to add up your actual expected monthly expenses in retirement: housing, food, transportation, healthcare, insurance, travel, and everything else. That number is your income target. From there you can work backwards to see whether your savings and Social Security will cover it, and what gap remains.
In one survey, 70% of women and 56% of men agreed it's difficult to know how their savings will translate into monthly retirement income. That uncertainty is exactly the problem Nanotoa is built to solve.
What are other people doing in this situation?
Ownership of retirement accounts shifts as people age. Among households in their late 40s, 401(k)-type accounts are far more common than IRAs. That gap narrows through the 50s and flips entirely by retirement age. Among households 65 and older, only 14.5% still hold a 401(k)-type account, while 40.2% own an IRA.
- Owns a 401(k)-type account
- Owns an IRA
| Age of household | Owns a 401(k)-type account | Owns an IRA |
|---|---|---|
| 35–44 | 54.6% | 22.5% |
| 45–54 | 55.0% | 28.0% |
| 55–64 | 38.4% | 35.6% |
| 65+ | 14.5% | 40.2% |
The crossover happens because people roll over their accounts as they retire. As they leave their jobs, money moves out of employer 401(k)s and into IRAs, and the focus shifts from building a balance to generating income from it.
Figuring out what your retirement income will be isn't an unusual situation. It's the question facing every household in their 50s and 60s, and most people are trying to answer it without a complete picture of what they actually have.
How can Nanotoa help?
Most people don't end their careers with a single retirement account. The average worker born between 1957 and 1964 held more than 12 jobs before age 54, and each one may have come with its own 401(k). It's no surprise that an estimated 29 million 401(k) accounts have been left behind or forgotten, holding well over $1 trillion in assets. When your money is scattered across old employers, brokers, and IRAs, it's hard to know what you actually have.
Nanotoa fixes that. We automatically pull all of your accounts: 401(k)s, IRAs, brokerage, savings, even your home and mortgage, into a single asset and liability ledger. Instead of logging into five different sites, you see your entire financial picture in one place.
Then we put that picture to work. Nanotoa projects what your income could look like if you retire at 62, 65, or 67, so you can see the trade-offs of each choice before you make them. That matters, because most people are flying blind. In one survey, 70% of women and 56% of men agreed it's difficult to know how their savings will translate into monthly retirement income.
Whether you're deciding what to do with an old 401(k) or just trying to understand if you're on track, Nanotoa turns a pile of disconnected accounts into one clear answer: here's what you have, and here's what it means for retirement.
Retirement Income Frequently Asked Questions
How much monthly income will I have in retirement?
It depends on three things: how much you've saved, when you retire, and when you claim Social Security. A rough starting point is the 4% rule: withdraw 4% of your total portfolio in your first year of retirement and adjust for inflation each year. Add your Social Security benefit at your chosen claiming age and you have a baseline monthly income estimate. For a more accurate picture you need your actual balances, your expected Social Security benefit (available at ssa.gov), and an honest look at your expected monthly expenses.
What is the 4% rule and does it still hold?
The 4% rule came out of the Trinity Study in 1998. Researchers found that a portfolio of 50 to 75% stocks could sustain 30 years of inflation-adjusted withdrawals at a 4% initial rate with a high probability of success. It became the standard rule of thumb for retirement income planning. Whether it still holds is debated. Some researchers argue that lower expected returns and longer life expectancies mean 3 to 3.5% is more prudent. Others point out that retirees who adjust their spending in bad market years can safely use 4% or higher. Think of it as a starting point rather than a guarantee.
When should I claim Social Security?
The right age depends on your health, your other income sources, and whether you're married. You can claim as early as 62, but your benefit is permanently reduced to about 70% of your full benefit if your Full Retirement Age is 67. Waiting past your FRA increases your benefit by 8% per year up to age 70, where it maxes out at roughly 124% of your full benefit. The break-even age, where the total lifetime benefit of waiting surpasses the total benefit of claiming early, is typically around 78 for the 62 vs 67 comparison. If you're in good health and expect to live into your 80s, delaying generally makes financial sense.
What is the Social Security break-even age?
The break-even age is the point where your total lifetime Social Security income from waiting equals what you would have received by claiming earlier. For the 62 versus 67 comparison it's typically around age 78. For 67 versus 70 it's around 82. If you live past your break-even age, the higher monthly benefit from waiting means you come out ahead in total lifetime income. If you die before it, claiming earlier would have paid more overall.
How does Social Security work for married couples?
Married couples have a few options that can increase total lifetime household benefits. A lower-earning spouse can claim a spousal benefit equal to 50% of the higher earner's full benefit, if that amount is more than their own earned benefit. When one spouse dies, the surviving spouse keeps the higher of the two benefits for life. This means the higher earner's claiming age affects both people. Delaying to 70 not only increases that person's monthly check but also maximizes the survivor benefit, which matters a lot if one spouse outlives the other by many years.
How does inflation affect retirement income?
Inflation erodes purchasing power over time. At 3% annual inflation, $5,000 per month today buys roughly what $2,760 buys today in 20 years. This is why most retirement income plans adjust portfolio withdrawals upward by the inflation rate each year. Social Security has a built-in cost-of-living adjustment tied to the Consumer Price Index, which offers some protection. Your portfolio withdrawals don't have that automatic adjustment, so your investments need to grow enough in real terms to sustain your income over the full length of your retirement.
What if my savings aren't enough to cover my expenses?
There are four levers: save more before retirement, retire later, spend less in retirement, or some combination. Working one or two extra years is often the most powerful option. It gives your portfolio more time to grow, cuts the number of years you'll need to draw on it, and increases your Social Security benefit if you haven't claimed yet. Part-time work in early retirement is also increasingly common. Even modest income of $1,000 to $2,000 per month can extend how long your portfolio lasts by several years.
What are Required Minimum Distributions (RMDs) and how do they affect my income?
Starting at age 73, the IRS requires you to withdraw a minimum amount from traditional IRAs and 401(k)s each year. The amount is calculated by dividing your account balance by a life expectancy factor from IRS tables. RMDs are taxed as ordinary income, which can push you into a higher tax bracket and affect Medicare premium calculations. Roth IRAs have no RMDs during the account owner's lifetime, which is one reason Roth conversions can be worth considering in your late 50s and early 60s before RMDs begin.
What is a safe withdrawal rate if I retire early?
The 4% rule was designed for a 30-year retirement. If you retire at 55 with a potential 40-year horizon, a lower withdrawal rate of 3 to 3.5% provides more protection against running out of money. Early retirees also face a bigger version of sequence-of-returns risk: a bad market in the first few years of retirement can permanently set back a portfolio even if markets recover later. Keeping 1 to 2 years of living expenses in cash or short-term bonds at the start of retirement can help you avoid selling equities at the worst possible time.
How much do I need to retire?
A common starting point is the 25x rule: multiply your expected annual retirement expenses by 25. This is just the inverse of the 4% rule. If you need $60,000 per year, you need $1,500,000 saved. That number goes down once you factor in Social Security. If Social Security covers $30,000 of your $60,000 in annual expenses, your portfolio only needs to generate the other $30,000, which requires $750,000 rather than $1,500,000. Your actual number depends on your expenses, your Social Security benefit, when you retire, and how much cushion you want.
What is the Trinity Study?
The Trinity Study is a 1998 paper by three professors at Trinity University that looked at historical portfolio performance to figure out what withdrawal rates were sustainable in retirement. They found that a retiree withdrawing 4% of their initial portfolio, adjusted for inflation each year, had a high probability of not outliving their money over a 30-year retirement. That finding is the origin of the widely used 4% rule. The study has been updated and debated many times since, but the core finding has held up reasonably well.
What is sequence of returns risk?
Sequence of returns risk is the problem that bad investment returns early in retirement can permanently damage your finances even if your long-term average returns end up being fine. A retiree who hits a major market decline in year one is in a much worse position than someone who hits the same decline in year ten, even if the average annual return over 30 years is identical. This is because early losses force you to sell more shares to cover withdrawals, leaving fewer shares to recover when markets bounce back. It's one of the main reasons people hold more conservative allocations early in retirement.
