Retirement Savings by Age Planner: Am I On Track?
"Am I on track?" is the most common financial question adults ask — and the hardest to answer without a benchmark. Fidelity's savings multiples give that benchmark: 1x salary by 30, 3x by 40, 6x by 50, 8x by 60, and 10x by 67. But a benchmark without context is just a number. This planner explains the math behind each milestone, shows what to do if you are behind, quantifies the real impact of catch-up contributions, higher savings rates, and a later retirement date, and builds realistic catch-up scenarios for the most common shortfall situations. Work through it and you will know exactly where you stand and what specifically to change.
1. Foundation
Fidelity's savings-by-age benchmarks are built on a consistent underlying model: a household saving 15% of income per year starting at age 25, invested in a diversified portfolio earning roughly 5.5% real after inflation, targeting an annual retirement income equal to 45% of pre-retirement income (the other 55% coming from Social Security and reduced spending). The benchmarks assume a retirement age of 67. When those assumptions roughly match your situation, the multipliers provide useful signposts. When they diverge — you started saving later, you plan to retire earlier, or your target income is higher than 45% of salary — the multipliers still provide a meaningful starting point, but need adjustment.
The math behind the 1x benchmark at age 30 is more demanding than it looks. A 25-year-old earning $50,000 who saves 15% ($7,500/year) earns a 4% raise annually and earns 5.5% real returns on investments will have saved roughly $50,000 by age 30 — very close to 1x their then-salary of about $60,000. But if they start saving at 28, or save only 8%, or earn 3% returns, they may arrive at 30 with $10,000–$20,000 rather than $50,000. Being at 0.5x at 30 is not catastrophic — there is decades of compounding ahead — but it signals that something in the model needs adjustment: start sooner, save more, or plan to work longer.
The jump from 1x at 30 to 3x at 40 is the hardest decade in the model. In that decade, you need to roughly triple your balance from 1x to 3x salary while salary itself is probably rising. If salary grows from $60,000 to $90,000 between ages 30 and 40, the 1x balance of $60,000 needs to become a 3x balance of $270,000 — a $210,000 increase. At a 15% savings rate on average salary of $75,000, annual contributions are $11,250. Over 10 years at 5.5% real returns, $60,000 invested grows to about $102,000 and $11,250 per year of new contributions grows to about $149,000, for a total of roughly $251,000. Close to target. Miss a few years of that savings rate due to a career break, student loans, or a home purchase, and the shortfall compounds quickly. The thirties are when the gap between on-track and behind-track first becomes material.
The 6x at 50 and 8x at 60 milestones are where catch-up contributions become critical. At age 50, the IRS allows an additional $7,500 catch-up contribution per year to 401(k) plans (2024 limits), on top of the standard $23,000 limit, for a total of $30,500. For IRAs, the catch-up is an additional $1,000 per year. Over 15 years from age 50 to 65, maximizing the full 401(k) catch-up produces roughly $790,000 in additional portfolio balance at 5.5% real returns — materially closing most mid-career gaps. The catch-up provision exists precisely because many households are behind at 50 and need a mechanism to accelerate without having to find entirely new income sources.
