Most people have a vague sense that they should be saving for retirement. They know they need “enough.” They hear numbers thrown around — a million dollars, two million, whatever their coworker said at lunch last week — and quietly hope they’re doing okay.
Here’s the uncomfortable truth: According to Northwestern Mutual’s 2026 Planning & Progress Study, 46% of Americans don’t expect to be financially prepared for retirement, and nearly half believe it’s likely they’ll outlive their savings.
That’s not said to scare you. It’s said because knowing where you actually stand is the first step to doing something about it. And that’s exactly what a retirement calculator is for.
The Number Everyone Is Chasing in 2026
Before getting into the math, here’s a data point worth knowing: Americans now believe they’ll need $1.46 million to retire comfortably — up more than $200,000 from last year, according to Northwestern Mutual’s 2026 study.
That number sounds daunting. But context matters — it’s an average across all ages, income levels, and lifestyle expectations. Your number could be significantly higher or lower depending on where you live, how you want to spend your retirement, and what other income sources you’ll have.
The goal of this post isn’t to give you someone else’s number. It’s to help you figure out yours.
The 4% Rule — The Most Useful Starting Point
If you want one simple framework to anchor your retirement planning, this is it.
The 4% Rule says: if you withdraw 4% of your retirement savings in your first year of retirement, then adjust for inflation each year after, your money will statistically last 30+ years.
Working backwards, this gives you a target:
Retirement savings needed = Annual spending in retirement ÷ 0.04
Or put another way — you need roughly 25 times your expected annual expenses saved up.
Real examples:
| Annual spending in retirement | Savings needed (4% Rule) |
|---|---|
| $40,000/year | $1,000,000 |
| $60,000/year | $1,500,000 |
| $80,000/year | $2,000,000 |
| $100,000/year | $2,500,000 |
Here’s the part people forget: this is your portfolio number — not your total income number. Social Security reduces how much your savings need to cover. The average Social Security benefit in 2026 is $2,071/month, or about $24,852/year. If you’re counting on that, subtract it from your annual spending target before applying the 4% rule.
So if you expect to spend $60,000/year and collect $25,000 in Social Security, your portfolio only needs to cover $35,000/year — which means $875,000 saved, not $1.5 million. That’s a meaningful difference.
How Much Should You Have Saved — By Age
Fidelity’s benchmarks are a widely used reference point. The general guideline is to have saved the following multiples of your annual salary by each age:
| Age | Savings Target |
|---|---|
| 30 | 1× your annual salary |
| 40 | 3× your annual salary |
| 50 | 6× your annual salary |
| 60 | 8× your annual salary |
| 67 | 10× your annual salary |
So if you earn $70,000/year and you’re 40, the benchmark says you should have around $210,000 saved. If you’re 50, roughly $420,000.
Don’t panic if you’re behind — most people are. These are targets, not verdicts. What matters more than where you are today is the direction you’re heading and what you do next.
The 401(k) — Your Most Powerful Retirement Tool
If you work for an employer that offers a 401(k), this is almost certainly where the bulk of your retirement savings should go.
Here’s why: contributions come out of your paycheck pre-tax, which lowers your taxable income today. The money grows tax-deferred, meaning you don’t pay taxes on the gains until you withdraw in retirement. And if your employer offers a match, that’s free money — arguably the best guaranteed return you’ll find anywhere.
2026 contribution limits (updated this year):
The 401(k) contribution limit for 2026 is $24,500 for employee salary deferrals. If you’re age 50 or older, you can make an additional catch-up contribution of $8,000, bringing your total to $32,500. And if you’re between ages 60 and 63 and your plan allows, a “super catch-up” contribution of $11,250 is available instead — meaning you could contribute up to $35,750 in 2026.
That super catch-up for 60–63 year olds is new and significant. If you’re in that window and you’re behind on savings, this is one of the most powerful tools available to you right now.
The one rule that overrides everything else: always contribute at least enough to get your full employer match. If your employer matches 50% of contributions up to 6% of your salary, contribute 6%. Anything less and you’re leaving part of your compensation on the table.
IRA — The Backup Plan (Or Bonus Plan)
An Individual Retirement Account (IRA) works similarly to a 401(k) but you open it yourself, independent of any employer.
IRA contribution limits for 2026 have risen to $7,500, with an additional $1,100 catch-up contribution for those 50 and older — allowing contributions of up to $8,600.
Two main types:
Traditional IRA — contributions may be tax-deductible now, and you pay taxes on withdrawals in retirement. Works well if you expect to be in a lower tax bracket later.
Roth IRA — contributions are made with after-tax dollars, but qualified withdrawals in retirement are completely tax-free. Works well if you expect to be in the same or higher tax bracket later — or if you just want tax-free income in retirement.
Most financial planners suggest maxing your 401(k) employer match first, then contributing to an IRA, then going back to your 401(k) if you have more to contribute.
Social Security — What It Will (And Won’t) Do
Social Security is part of the picture, but banking on it as your primary retirement income is a mistake.
You can check your estimated benefit at SSA.gov/myaccount — it’s free and takes about three minutes. The statement shows your estimated monthly benefit at different claiming ages.
A few things worth knowing:
Claiming age dramatically affects your benefit. Full retirement age (FRA) is 67 for anyone born in 1960 or later. If you delay claiming to age 70, you get an 8% annual bonus for each year past FRA — potentially up to $5,200/month at maximum. If you claim early at 62, your benefit is reduced by roughly 25%.
That 8-year difference between claiming at 62 versus 70 can add up to hundreds of thousands of dollars over a long retirement — particularly if you’re in good health and expect to live into your 80s or beyond.
Don’t assume Social Security will stay exactly as it is. There’s ongoing political and fiscal uncertainty around the program’s long-term funding. Factor it in as part of your plan but not as a guarantee.
The Honest Conversation About Healthcare
This is the number most retirement calculators underplay, and it blindsides people.
Fidelity estimates a 65-year-old couple needs approximately $315,000 in today’s dollars for healthcare costs in retirement. That’s not including long-term care — it’s just regular medical expenses, premiums, co-pays, and out-of-pocket costs.
Medicare starts at 65. If you retire before 65, you’ll need to bridge that coverage gap. Expanded ACA subsidies expired at the end of 2025, reverting to pre-2021 rules — meaning premium tax credits disappear for households earning above roughly $84,600 and are reduced for many others. Early retirees need to factor healthcare costs carefully.
Health Savings Accounts (HSAs) are one of the most underused retirement tools available. The 2026 HSA contribution limits are $4,400 for individuals and $8,750 for families. Funds invested in an HSA grow tax-free and can be used for Medicare premiums.
If you’re eligible for an HSA, maxing it out is one of the smartest moves you can make.
What Age Are You? Here’s Where to Focus
Retirement planning looks different depending on where you are in life. Here’s a quick snapshot:
In your 20s: Time is your biggest advantage. Even $100/month invested consistently from age 22 compounds dramatically over 40+ years. Get in the habit early, even if the amounts feel small. Enroll in your 401(k) and set it to auto-increase by 1% each year.
In your 30s: Life gets expensive — mortgages, kids, cars. But this decade matters enormously for compounding. Aim to hit the 1x salary benchmark by 30, 3x by 40. Automate contributions so the decision gets made once, not monthly.
In your 40s: The gap between where you are and where you need to be starts becoming clear. If you’re behind, the answer isn’t panic — it’s increasing your savings rate consistently. Every 1% more you save matters. Don’t cash out 401(k)s when changing jobs; roll them over.
In your 50s: Now you’re in catch-up territory. Max out your 401(k), take advantage of catch-up contributions ($8,000 extra in 2026). Four in 10 Americans plan to work during their retirement years — not just for income, but because they want to stay engaged. Part-time work in early retirement can meaningfully extend how long your savings last.
In your 60s: Workers ages 60 through 63 may be eligible for a “super catch-up” contribution of up to $11,250 in 2026 — potentially bringing total elective deferrals plus catch-up contributions to as much as $35,750 per year. Think carefully about Social Security timing. Consider your healthcare bridge if retiring before 65.
Use the Calculator — Then Revisit It Every Year
Numbers on paper only mean something when you connect them to your actual situation. Our Retirement Calculator lets you enter your current savings, monthly contribution, expected return, and retirement age — and shows you whether you’re on track or how big a gap you’re working with.
Run it once today. Then run it again every year. As your salary grows, as your expenses shift, as markets move — your number changes. Retirement planning isn’t a one-time calculation. It’s an ongoing habit of checking in and adjusting.
If you’re also building wealth through regular monthly investments alongside retirement savings, our Investment Calculator and SIP Calculator can help you model how those contributions grow over time.
Frequently Asked Questions
What if I’m starting late — is it too late to save? It’s never too late, but you’ll need to save more aggressively. Someone starting at 50 needs to save a higher percentage of income than someone starting at 25 to reach the same goal. The catch-up contribution rules exist for exactly this reason — use them.
Should I pay off my mortgage before retiring? Ideally, yes — retiring debt-free significantly reduces your monthly income needs and therefore how much you need saved. But it’s not always the right trade-off; if your mortgage rate is low and your investments are returning more, the math may favor investing over accelerating mortgage payoff.
How do Required Minimum Distributions (RMDs) work? You can generally wait until age 59½ to withdraw from a 401(k) without penalty, but you must begin taking Required Minimum Distributions starting at age 73. RMDs are taxable income, so planning around them can affect your tax situation in retirement.
What’s a realistic investment return to assume? The S&P 500 has historically returned around 10% annually, or about 7% after adjusting for inflation. For conservative retirement planning, most planners suggest using 6–7% for pre-retirement growth and 4–5% for post-retirement portfolio growth.
What if Social Security changes? Build your plan assuming you’ll receive some portion of your estimated benefit — perhaps 75–80% if you want to be conservative — rather than banking on the full amount or assuming it disappears entirely. Either extreme is probably too pessimistic or too optimistic.
