Retirement Planning

The process of building financial resources to sustain your lifestyle after you stop working — starting with employer-sponsored accounts like 401(k)s and expanding from there.

Retirement planning is the ongoing process of building financial resources sufficient to fund your lifestyle after you stop earning a regular income from work. In the employer context, it centers on making the most of workplace retirement benefits: 401(k) plans, employer matching contributions, Roth options, HSAs (which function as a triple-tax-advantaged retirement account for healthcare expenses), and pension plans where they still exist. For most employees, the employer-sponsored 401(k) with matching contributions is the single highest-return investment they can make — a 100% employer match on the first 3% of salary contributions is an immediate 100% return before any market gains.

The mathematics of retirement planning are dominated by compound growth and time horizon. The most powerful variable is not your contribution rate or your investment returns — it's how early you start. An employee who contributes $500/month starting at age 25 and stops at 35 (10 years of contributions) will typically retire with more than one who contributes the same $500/month starting at 35 and continues until 65 (30 years of contributions), assuming similar returns. This counterintuitive result — the early starter wins despite fewer contributions — illustrates why front-loading contributions early in a career has an outsized long-term impact, even during years when salary is low.

Beyond the 401(k), a complete retirement strategy typically includes: an emergency fund (3–6 months of expenses) separate from retirement savings; an IRA (traditional or Roth) to contribute beyond the 401(k) if income permits; taxable brokerage accounts for savings above tax-advantaged limits; and, for many people, home equity as a component of net worth. Financial advisors and retirement calculators often use a target of replacing 70–80% of pre-retirement income, though actual needs vary considerably based on expected healthcare costs, housing situation, lifestyle, and whether Social Security will provide meaningful income.

Workplace Retirement Accounts: What to Prioritize

The highest-priority action for most employees is contributing enough to the 401(k) to capture the full employer match — this is free money with an immediate 50–100% return before any investment performance. Beyond the match, the choice between a traditional (pre-tax) 401(k) and Roth 401(k) depends on whether your marginal tax rate is higher now or expected to be higher in retirement: if you expect to be in a higher bracket later, the Roth is usually better (pay taxes now at the lower rate, withdraw tax-free later). If you're in a high bracket now and expect retirement income to be lower, traditional pre-tax contributions reduce your current tax bill. Many plans allow a split — some to traditional, some to Roth — which hedges tax risk. After the 401(k) match, consider maxing an HSA (if you have a high-deductible health plan) before additional 401(k) contributions, because the HSA is the only account with triple tax advantages: contributions are pre-tax, growth is tax-free, and withdrawals for qualified medical expenses are tax-free.

Rules of Thumb Worth Knowing

  • At minimum: contribute enough to get the full employer match — not doing so is leaving part of your compensation on the table.
  • Target: 15% of gross income including employer contributions, per Fidelity and most financial planners. This is a starting point, not a ceiling.
  • 2024 contribution limits: $23,000 to a 401(k); $7,000 to an IRA ($8,000 if 50+); $4,150/$8,300 to an HSA (individual/family).
  • Age-based milestones (Fidelity's rule of thumb): 1x salary saved by 30, 3x by 40, 6x by 50, 8x by 60, 10x by 67.
  • Social Security: check your estimated benefit at ssa.gov. For most workers, this replaces 40–50% of pre-retirement income — the rest needs to come from savings.
  • When you change jobs: roll over your old 401(k) to an IRA or new 401(k) — don't cash it out.

Example

An employee earning $80,000 gets a 4% employer 401(k) match. Contributing 4% means she contributes $3,200/year and gets $3,200 from her employer — an effective 100% return on that $3,200 before any market gains. If she contributes only 2% instead, she leaves $1,600 of employer matching on the table every year — $16,000 over 10 years, not accounting for compounding.
