Retirement Savings By Age Calculator: Am I On Track?

What this calculator actually answers

“How much should I have saved by the time I’m 40?” is the most common retirement question that has a real answer, because the answer is a rule of thumb, not a projection. The widely cited Fidelity guideline says: have 1× your salary saved by 30, 3× by 40, 6× by 50, 8× by 60, and 10× by 67. This calculator runs your actual numbers — age, salary, savings so far, monthly contribution, and an expected return — forward against that staircase, and reports where you stand at every rung.

That is a different question from the 401(k) calculator’s. The 401(k) tool asks what a specific account will hold at retirement — a sticker price in future dollars. This tool asks whether your whole savings picture is on track, which is the question the milestones exist to answer. The FIRE calculator tells you what balance you need to retire early; this one tells you whether the balance you are building will actually be there. And when the pace check says you need to save more, the savings rate retirement date calculator shows what each higher rate buys back in years.

The benchmark rule

The milestones are multiples of salary because retirement spending scales with income, and a salary-linked yard stick is comparable across households and roughly inflation-proof: if your salary keeps pace with inflation, the multiple stays meaningful in today’s dollars with no separate adjustment. The yard stick is the gross annual salary, not the paycheck — if your pay is quoted hourly, the hourly to salary calculator produces the annual number the multiples are measured against. That is why this calculator has no inflation input — the benchmark is already in the currency that matters.

The rule is a staircase, not a slope: between the named ages the previous multiple holds, and the jumps happen at the decade boundaries. The chart draws it that way — a step line rising at each milestone against the smooth growth curve of the projection. Where the two lines cross is where you are ahead.

The projection math

The projection is the standard monthly-compounding recurrence, identical to the 401(k) calculator’s engine: a starting balance $P$ earning $r/12$ per month with a monthly deposit $M$ added at the end of each month, for $n$ months:

At every age from today to retirement, the balance is compared with the salary multiple in force at that age:

The gap is the difference between the two. The model also inverts the formula to answer the follow-up question: given the balance already saved and the years remaining, what monthly deposit reaches the retirement benchmark exactly?

The defaults tell the real story

Run the defaults — a 35-year-old earning $85,000 with $60,000 saved, contributing $700 a month, at a 7% return. The milestone table is the honest picture:

This is not a contradiction; it is the shape of compounding. The projection misses the 3× target at 40 and the 6× target at 50 — a mid-career saver starting from $60,000 simply cannot reach $255,000 in five years without contributions of $2,374 a month. But the curve is rising faster than the staircase: it crosses the benchmark between 50 and 60, and the last decade does most of the work. By 67 the projection clears the 10× target by $709,832, and the calculator reports that the target could actually be hit with just $203 a month from here.

The lesson cuts both ways. A 45-year-old with these same inputs faces the 6× target of $510,000 at 50 with $135,173 projected — the same shortfall the 35-year-old saw at 40, but with ten fewer years to fix it. The milestones exist to make the shortfall visible while the correction is still cheap.

The dials that matter

The return assumption moves the outcome far more than the contribution. At the default savings level:

The 9% column clears the 6× target at 50; the 5% column does not clear the 10× benchmark at 67 at all. Two percentage points of assumed return swing the projection by over a million dollars — which is precisely why the 401(k) calculator and this page both default to a middle-of-the-range 7% and tell you to use after-fee expectations.

The contribution dial is more controllable and matters more early on:

Even $1,000 a month does not clear the 3× target at 40 from the default starting point — it takes $2,374 a month, more than three times the contribution. The milestone at 40 is a stretch goal for anyone starting late; the retirement benchmark at 67 is the one the projection is actually built to hit. Both are worth knowing, and they are different numbers.

Where the assumptions break

• A static salary. Real salaries grow with raises and promotions, and the benchmarks scale with them. Holding salary flat makes the targets easier than they will really be — and the projection’s own contributions are also flat, which pushes the other way.
• A static contribution. The model holds the monthly deposit fixed for the whole horizon. Most savers contribute more as income rises, which the projection understates.
• A static rate. One return for 32 years, no sequence-of-returns risk. As the return table shows, this single assumption dominates the outcome.
• No other retirement income. Social Security, a pension, and a spouse’s savings all reduce how much of your spending the portfolio must cover. The multiples are a gross guideline, not a net calculation.
• The rule itself. The Fidelity staircase is a reasonable heuristic, not a law — a household with low retirement expenses can be fine below it, and one with high expenses can be behind above it. Use it as a milepost, and the FIRE calculator as the precise answer to “how much do I need.”

None of these make the milestone check wrong; they make it a screen, not a verdict. The value is in seeing the shortfall while there is still time to fix it — the same reason the inflation-adjusted savings goal calculator exists for specific targets rather than general ones.

How to use this calculator

• Current age picks where the projection starts and which milestone is next. The earlier the age, the more compounding works for you — a 25-year-old with these inputs clears the 1× target at 30 and never looks back.
• Retirement age sets where the projection ends and which benchmark applies there. Ages 60–66 use the 8× multiple; 67 and above use 10×.
• Annual salary is the base every benchmark is measured against. Enter your current salary — the rule is designed around it.
• Already saved is the balance in all retirement accounts combined: 401(k), IRA, brokerage earmarked for retirement. The Roth vs. Traditional IRA calculator is the companion question to this page — which account to put that money in once the track check says you’re saving enough.
• Monthly contribution is what you set aside each month across all accounts. The 50/30/20 budget calculator is the place to find a rate you can sustain.
• Expected return is the after-fee nominal rate you expect. 7% is the historical ballpark for a diversified equity-heavy portfolio; use 5% for a conservative check and 9% for an optimistic one.

The currency selector changes symbols only — figures are not converted by an exchange rate. The benchmark is a multiple of salary in whatever currency you enter, so the check itself is currency-agnostic.

The milestones are the point of this page: they convert “am I saving enough?” from a vague anxiety into a specific, dated comparison. Behind at 40 but ahead at 67 is a normal trajectory for a saver who starts late and stays consistent — the calculator’s job is to show you which of those two statements is true for your numbers, and how much the correction costs while you still have time to make it.
