How much do I need to retire?

The standard benchmark is 25x your annual expenses in retirement — based on the "4% rule," which suggests you can withdraw 4% of your portfolio annually with a high probability of the money lasting 30+ years. If you expect to spend $60,000/year in retirement, you need approximately $1.5 million saved. Your number will vary based on Social Security income, lifestyle, and retirement timeline.

What rate of return should I use in a retirement calculator?

A conservative assumption is 5–6% annually for a balanced portfolio (mix of stocks and bonds) after inflation. The historical long-term return of the US stock market is approximately 10% nominal, but calculators that use this figure may be overly optimistic. Use 6–7% for an all-equity assumption, 5% for a balanced portfolio, and always run a conservative scenario at 4–5%.

I'm behind on retirement savings. What should I do?

First, run an accurate projection to understand the actual gap — the situation is often better or worse than people assume. Then focus on the variables you can control: contribution rate (most impactful when made early), expected retirement age (working two years longer can dramatically improve outcomes), and expected spending in retirement (reducing by 10–15% has a significant effect on how long your money lasts).

Retirement Planning Calculator: How to Know If You're on Track

Why Retirement Planning Calculators Matter

Most people know they should be saving for retirement. Most people have a vague sense they're probably behind. What most people lack is a specific number — a clear answer to "based on what I'm doing now, when can I retire, and will I have enough?"

A retirement planning calculator answers that question. It transforms "I hope I'm okay" into either "I'm on track" or "here's exactly what I need to change."

The Core Inputs Every Retirement Calculator Needs

Current Savings Balance

The total of all retirement-earmarked accounts: 401(k), 403(b), Traditional IRA, Roth IRA, SEP-IRA, and any other long-term investment accounts you're planning to use for retirement.

Monthly Contribution

How much you're currently adding each month across all retirement accounts, including employer matching contributions.

Expected Rate of Return

The average annual return you expect from your investments. A common conservative assumption for a balanced stock/bond portfolio is 5–6% annually (in real, inflation-adjusted terms). For an equity-heavy portfolio, 6–7% is reasonable. Avoid using the historical 10% nominal return — it's optimistic and doesn't account for sequence-of-returns risk.

Years Until Retirement

Your current age minus your target retirement age. This is one of the most powerful variables in the calculation — time in the market has an enormous effect on outcomes.

Retirement Income Needed

How much you expect to spend annually in retirement. Common rule of thumb: 70–80% of your pre-retirement income. This varies based on whether your mortgage will be paid off, your healthcare costs, and your lifestyle expectations.

The 4% Rule: Your Retirement Number Benchmark

The most widely used retirement benchmark: you need 25x your expected annual retirement spending saved.

Spending $40,000/year → need ~$1,000,000
Spending $60,000/year → need ~$1,500,000
Spending $80,000/year → need ~$2,000,000

Social Security reduces this target. The average Social Security benefit in 2024 is approximately $1,907/month ($22,884/year). If that covers a third of your expected expenses, your required portfolio is significantly smaller.

What to Do When the Calculator Says You're Behind

Increase Your Contribution Rate

This is the single highest-leverage action. Even a 1–2% increase in your contribution rate, made today, compounds significantly over time. If you get a raise, commit to directing at least half of it to retirement contributions before it gets absorbed into lifestyle inflation.

Push Your Retirement Age

Working two years longer has three effects: two more years of contributions, two fewer years of withdrawals, and a higher Social Security benefit. The mathematical impact is often larger than people expect.

Reduce Expected Retirement Spending

A 10% reduction in expected retirement spending has the same effect as roughly 2.5 extra years of saving. This doesn't mean deprivation — it means being realistic about what your retirement lifestyle will actually cost.

Consider Catching Up Contributions

If you're over 50, the IRS allows "catch-up" contributions above the standard limit. In 2025, the 401(k) catch-up limit is $7,500 additional per year. Maximizing this aggressively in the decade before retirement can make a significant difference.

How Avenue Handles Retirement Planning

Avenue connects to your retirement accounts and runs ongoing projections based on your actual balances and contribution rates. Rather than running a one-time calculation, Avenue monitors your trajectory continuously — and alerts you when changes in your situation (a raise, a contribution change, market fluctuations) shift your projected outcomes meaningfully.

You can also model specific scenarios: "What if I increase my 401(k) contribution from 8% to 12%?" or "What if I retire at 62 instead of 65?" — and see the impact on your projected retirement balance instantly.
