Frequently Asked Questions
Complete Retirement Planning Guide
Retirement planning is the single most important financial exercise you'll undertake. Unlike other financial goals, retirement has a fixed deadline and escalating costs due to healthcare, longevity risk, and inflation. Starting early and planning systematically makes the difference between financial security and struggle in your later years.
The Three-Legged Stool of Retirement Income
Traditional retirement planning relies on three income sources: Social Security (government guarantee, claim optimally), Pension/Employer Plans (401k, 403b — maximize employer match), and Personal Savings (IRA, taxable brokerage, real estate). Diversifying across these ensures resilience if any one source underperforms.
Sequence-of-Returns Risk
The order of returns matters more than average returns in retirement. A market crash in your first 5 years of retirement can permanently impair your portfolio even if long-term averages recover. Mitigation strategies include a 2-year cash buffer, the bucket strategy (cash/bonds/stocks), and flexible spending (reduce 10-15% in down years).
The Impact of Starting Age
Saving $500/month from age 25 to 65 at 7% grows to $1.32M. Starting at 35 grows to only $606k. Starting at 45 grows to $248k. The $500/month missed from 25-35 costs you $1.07M in retirement — the price of waiting 10 years is enormous.
Healthcare Planning
Healthcare is the wildcard in retirement planning. Fidelity estimates a couple retiring at 65 needs $315,000 for healthcare costs in retirement. Budget $300-600/month for premiums and out-of-pocket before Medicare, and consider a long-term care insurance policy in your 50s when premiums are still manageable.
