Retirement Savings Gap Calculator

You’ve been saving for years. You’ve got a 401(k), maybe an IRA, maybe both. But somewhere around your mid-40s, a question starts creeping in at 2am: am I actually going to be okay?

It’s not an irrational fear. Most women in their 40s and 50s genuinely don’t know if they’re on track for retirement — not because they haven’t been responsible, but because nobody ever showed them the actual math. You’ve been contributing in the dark, hoping the number eventually works out.

It doesn’t have to stay a guessing game. The calculator below does the math for you — and more importantly, tells you exactly what to do if the number comes up short.

Why So Many Women Are Behind — and Why It’s Not Your Fault

Women retire with significantly less saved than men, on average. This isn’t a mystery or a character flaw. It’s the direct result of a few well-documented patterns: career breaks for caregiving, the gender pay gap compounding over decades, and more time spent in part-time or lower-benefit roles.

None of that is something you can undo retroactively. But it does mean the standard retirement advice — generic rules of thumb built around uninterrupted, full-time careers — often doesn’t reflect your actual situation. Catching up isn’t about beating yourself up over decisions you made in your 30s. It’s about understanding exactly where you stand today and making a clear-eyed plan from here.

Why “Am I On Track?” Is the Wrong Question to Guess At

Most people either avoid this question entirely or answer it with a vague feeling — “I think I’m okay” or “I probably should be saving more.” Neither helps you make an actual decision.

The real question has three parts: how much will your current savings and contributions realistically grow to by the time you retire, how does that compare to what you’ll actually need, and if there’s a gap, what specifically needs to change to close it. That’s exactly what this calculator answers — no vague feelings required.

Calculate Your Retirement Savings Gap

Fill in your numbers below. The growth rate slider lets you test different market assumptions — 7% is a commonly used long-term average, but you can adjust it to be more conservative or more optimistic.

What to Do If You’re Behind

If the calculator shows a gap, take a breath. A gap today is a starting point, not a verdict. Here’s how to think about closing it, in order of impact.

Increase your contribution percentage, even slightly. Going from 8% to 10% of your income often feels smaller than expected month to month, but compounds significantly over 15–20 years. Small increases now matter more than large increases later, simply because they have more time to grow.

Use catch-up contributions if you’re 50 or older. The IRS allows additional contributions to 401(k)s and IRAs once you hit 50, specifically because lawmakers recognize that many people — women especially — need to catch up later in their careers. If you haven’t already, this is worth exploring with the 401(k) Catch-Up Calculator on this site.

Consider working a few years longer. This isn’t always the answer anyone wants to hear, but two or three additional working years can do more for your retirement number than almost any other single change — both by adding contributions and by giving your existing savings more time to compound.

Check your employer match. If your employer matches contributions and you’re not contributing enough to get the full match, that’s the very first thing to fix before anything else. It’s the closest thing to free money in personal finance.

What If You’re Already On Track?

Good — but don’t stop checking. Life changes: income shifts, expenses change, markets move. Revisit this calculator at least once a year, ideally whenever something significant changes in your finances (a raise, a new job, paying off a mortgage). Staying on track isn’t a one-time achievement — it’s an ongoing habit of checking in.

A Note on the Numbers Here

This calculator gives you a projection, not a guarantee. Markets don’t grow in a smooth, predictable line — some years will be up significantly, others down. The growth rate slider lets you stress-test your plan against more conservative assumptions, which is generally the wiser way to plan: hope for the average, but build your plan around something a bit more cautious.

This tool also doesn’t account for taxes, required minimum distributions, Social Security, or other income sources you may have in retirement — all of which affect your real-world number. Think of this as a directional gut-check, not a substitute for working with a financial planner once your number gets close to your goal.
