How to Plan for Retirement: The Complete Step-by-Step Guide
Retirement planning is not a single decision — it's a system. Six interconnected steps, each building on the last, from calculating your number to structuring your withdrawal strategy. This guide covers everything.
How to Use This Guide
This is Plootus's master retirement planning guide — it covers every major decision from first savings to first withdrawal. Each section links to a dedicated deep-dive guide for more detail.

Calculate Your Retirement Number
Everything in retirement planning flows from one number: how much you need saved to sustain your desired lifestyle indefinitely. This is your retirement number, and getting it right is the foundation of every other decision.
The most widely used framework is the 4% rule: multiply your anticipated annual spending by 25 to get your required portfolio. At a 4% annual withdrawal rate, historically diversified portfolios have survived at least 30 years in nearly every market scenario studied (Bengen, 1994; Trinity Study updates).
The Formula
(Annual Spending − Social Security Income) ÷ 0.04 = Retirement Number
The average Social Security benefit is $24,894/year (SSA, Nov. 2025). If you plan to spend $70,000/year, your savings only need to cover the $45,106 gap — meaning a target of ~$1.13 million, not $1.75 million.
| Desired Annual Spending | After SS Income ($24,894 avg.) | Retirement Number (4% Rule) | State Example |
|---|---|---|---|
| $50,000/year | $25,106 | $627,650 | Mississippi, Oklahoma |
| $60,000/year | $35,106 | $877,650 | Iowa, Indiana |
| $75,000/year | $50,106 | $1,252,650 | North Carolina, Florida |
| $90,000/year | $65,106 | $1,627,650 | Colorado, Virginia |
| $120,000/year | $95,106 | $2,377,650 | California, New York |

Understand Your Retirement Accounts
Different retirement accounts have different tax treatments, contribution limits, and withdrawal rules. Using the right mix — and contributing in the right order — can save tens of thousands in taxes over your retirement lifetime.
The Right Contribution Order
401(k) — up to the employer match
This is free money. Contribute enough to get the full employer match — it's an immediate 50–100% return. One in four workers misses out on this entirely (Fidelity, 2025).
HSA — maximum, if eligible
If you have a high-deductible health plan, max your HSA. The only truly triple-tax-advantaged account: deductible, grows tax-free, and tax-free qualified withdrawals at any age.
Roth or Traditional IRA — $7,000
Max your IRA after the employer match. Roth if in lower tax brackets now; Traditional if in peak earning years. Subject to income limits for Roth deductibility.
Max out 401(k) — remaining $17,500
Return to your 401(k) and contribute up to the full $24,500 limit. At 50+: add catch-up ($8,000 standard; $11,250 if ages 60–63 under SECURE 2.0).
Taxable brokerage — no limit
If you've maxed all tax-advantaged accounts, a taxable brokerage is next. Focus on tax-efficient investments: index funds, ETFs, and minimize trading.

Choose Where to Retire
Location is one of the most underweighted retirement variables — yet it can change your required savings by $500,000 to $1.5 million. A retiree in Hawaii needs over $2.6 million using the 4% rule. The same lifestyle in Tennessee requires under $650,000 (Plootus Best States to Retire, 2026).
Four factors determine the financial impact of your retirement location: cost of living, state income taxes, healthcare quality, and quality of life.
| Factor | Why It Matters | Best States | Worst States (for factor) |
|---|---|---|---|
| Cost of Living | Determines annual spending and retirement number | MS, OK, KS, TN, AR | HI, CA, NY, MA, NJ |
| Income Tax | Can cost $5K–$20K+/year on retirement distributions | WY, FL, TN, SD, NV | CA, NY, NJ, CT, MN |
| Healthcare Quality | Critical in 70s–80s; poor access can devastate finances | MN, CO, MA, SD | KY, WV, MS, OK |
| Quality of Life | Climate, community — matters for well-being and longevity | FL, ME, CO, VT, WI | MS, AR, KY, LA |
💡 Best Value States (Cost + Quality): Tennessee (no income tax, low cost), North Carolina (affordable, strong QoL), Delaware (A tax grade, near major medical centers), and Florida (no income tax, warm climate) offer the strongest combination of affordability and livability.

Optimize Your Social Security Strategy
Social Security is worth $300,000–$500,000+ in lifetime income for the average retiree. The claiming age decision is permanent and irrevocable — and most people make it without adequate analysis.
| Claim At | Monthly Benefit (example: $2K FRA) | Annual Benefit | Break-Even Age | Best For |
|---|---|---|---|---|
| 62 (earliest) | $1,400 (−30%) | $16,800 | ~77 vs. FRA | Poor health; urgent income need |
| 67 (Full Retirement Age) | $2,000 (100%) | $24,000 | Baseline | Average health; standard retirement |
| 70 (maximum delay) | $2,480 (+24%) | $29,760 | ~83 vs. FRA | Good health; maximize survivor benefit |
For couples: the higher earner should strongly consider delaying to age 70 to maximize the survivor benefit — the benefit the lower-earning spouse inherits if the higher earner dies first. This single decision can add $50,000–$200,000 in additional lifetime household income.

Plan for Healthcare Costs
Healthcare is the most common cause of retirement plan failure — not poor investment returns. Fidelity estimates a couple retiring today at 65 will spend an average of $413,000 on healthcare throughout retirement, excluding long-term care (Fidelity Retiree Health Care Cost Estimate, 2024).
The Four Healthcare Phases in Retirement
Ages 55–64: The Pre-Medicare Gap (if retiring early)
The most financially dangerous healthcare period. ACA Marketplace plans, COBRA, or spouse's employer coverage. Budget $10,000–$25,000/year depending on age and plan.
Ages 65–74: Early Medicare Years
Enroll in Medicare Parts A, B, and D at 65. Annual costs: ~$8,500–$13,500 for a single retiree in average health. Max and preserve your HSA reserve for later years.
Ages 75–84: Rising Health Needs
Healthcare spending accelerates. Long-term care planning becomes urgent. Annual costs: $13,000–$19,000+ without LTC coverage. Ensure adequate Medigap or Medicare Advantage.
Ages 85+: Long-Term Care Potential
70% of those reaching 65 will need some form of LTC. Median assisted living: $64,200/year. Nursing home (private room): $108,405/year. Medicare does not cover custodial care (Genworth Cost of Care Survey, 2024).
Build Your Withdrawal Strategy
How you withdraw from retirement accounts is just as important as how much you saved. The order, timing, and structure of withdrawals can save $50,000–$200,000 in lifetime taxes and significantly extend how long your money lasts.
The Optimal Withdrawal Order
Required Minimum Distributions (RMDs) first
Once you reach age 73, the IRS requires minimum annual withdrawals from traditional IRAs and 401(k)s. Missing them triggers a 25% penalty. Take RMDs first.
Taxable brokerage accounts
Taxed at capital gains rates (typically 0% or 15%) — significantly lower than ordinary income rates. Use these while tax-deferred accounts continue growing.
Traditional IRA / 401(k) withdrawals
Taxed as ordinary income. Strategic withdrawal amounts can keep you in lower tax brackets. In early retirement years (before SS begins), these can be taken at very low rates.
Roth IRA — save for last
Tax-free growth and no RMDs make Roth IRA the most flexible account. Save it for later retirement when tax rates may be higher, healthcare emergencies, or as a legacy asset.
The Roth Conversion Strategy
In the years between retirement and age 73 (when RMDs begin), many retirees can strategically convert traditional IRA funds to Roth at low tax rates — filling lower tax brackets before RMDs force larger withdrawals later. Done over 8–12 years, this strategy can reduce lifetime tax burden by $50,000–$200,000 (T. Rowe Price, 2025).
