When to Use

Trigger when the user says:

• /finance retirement
• "Am I on track for retirement"
• "How much do I need to retire"
• "When can I retire"
• "Social Security timing"
• "401k vs Roth"
• "Withdrawal strategy"

Data Collection

Demographics

1. Current age
2. Target retirement age
3. Spouse age and retirement age (if applicable)
4. Life expectancy assumption (default age 95; longer if family history)
5. State for retirement (tax implications)

Current Retirement Assets 6. 401k / 403b / TSP balance and contribution 7. Traditional IRA balance and contribution 8. Roth IRA balance and contribution 9. Roth 401k portion (if applicable) 10. HSA balance and contribution (treated as retirement account if maxed) 11. Taxable brokerage earmarked for retirement 12. Pension (annual benefit at retirement, COLA y/n) 13. Real estate equity earmarked for retirement

Income & Contributions 14. Employee contribution rate (% or $) 15. Employer match formula and current capture rate 16. Annual raises expected 17. Catch-up contributions if 50+

Retirement Spending 18. Expected annual spending in retirement (today's dollars) 19. Mortgage paid off by retirement? (changes spending) 20. Healthcare plan (Medicare + supplement, ACA, employer retiree) 21. Travel / lifestyle changes

Social Security 22. Estimated benefit at full retirement age (from SSA.gov) 23. Spouse's estimated benefit 24. Years worked (must be 35 for max benefit)

Calculation Methodology

Required Nest Egg

Method 1: 25x Rule (4% Safe Withdrawal Rate)

Nest Egg Needed = Annual Spending × 25

Example: $80,000 spending × 25 = $2,000,000

Method 2: Subtract Other Income

Nest Egg = (Annual Spending - Social Security - Pension) × 25

Example: ($80k - $30k SS - $0) × 25 = $1,250,000

Method 3: Inflation-Adjusted For target retirement year, multiply today's needed spending by inflation factor:

Future Spending = Today's Spending × (1.03)^years_to_retirement
Future Nest Egg = Future Spending × 25

Example: $80k × (1.03)^25 = $167,500 → × 25 = $4,187,500 at retirement

Report nest egg in BOTH today's dollars and future dollars.

Projected Nest Egg

Use compound growth formula across three scenarios:

FV = PV × (1+r)^n + PMT × [((1+r)^n - 1) / r]
Where:
  PV = current balance
  PMT = annual contribution
  r = real return rate
  n = years to retirement

Conservative: 5% real return (3% above inflation) Moderate: 6% real return Aggressive: 7% real return

Gap Analysis

Gap = Needed - Projected
Required Additional Monthly Contribution = Gap / [((1+r)^n - 1) / r] / 12

Monte Carlo Logic (Simulated)

Without running thousands of trials, present a "Monte Carlo-style" outcome range:

• 90th percentile (great markets): Nest egg = projected × 1.5
• 50th percentile (median): Nest egg = projected × 1.0
• 10th percentile (poor markets): Nest egg = projected × 0.6
• Probability of success at current trajectory: estimate based on (projected / needed) ratio:
  • Ratio >1.3: ~95% success
  • Ratio 1.0-1.3: ~80% success
  • Ratio 0.8-1.0: ~60% success
  • Ratio 0.6-0.8: ~35% success
  • Ratio <0.6: <20% success

Asset Allocation by Age

Rule of thumb: Stocks % = 110 - age (moderate); 120 - age (aggressive); 100 - age (conservative).

Social Security Optimization

Claiming ages:

• Age 62: Earliest, ~75% of FRA benefit (permanent reduction)
• Age 67 (FRA for those born 1960+): 100% of benefit
• Age 70: 132% of FRA benefit (8% annual delayed retirement credits stop at 70)

Breakeven analysis:

• Age 62 vs 67: Breakeven around age 78
• Age 67 vs 70: Breakeven around age 82-83
• Age 62 vs 70: Breakeven around age 80

Recommendation logic:

• Longevity in family + don't need cash → delay to 70
• Health issues / shorter life expectancy → claim early
• Spouse: file-and-suspend strategies; survivor benefit = higher of two
• Working between 62-67 → earnings test reduces benefits

Healthcare Cost Projection

• Average couple needs $315,000 in retirement for healthcare (Fidelity, today's dollars)
• Pre-Medicare (retiring before 65): ACA subsidies, COBRA, retiree plans
• Medicare starts age 65: Parts A free, B ~$175/month, D varies, supplement (Medigap) $150-400/month
• HSA is most tax-efficient bucket for healthcare (triple tax advantage)

Withdrawal Sequence (Order of Spending)

Most tax-efficient order:

1. Required Minimum Distributions (RMDs) from Traditional 401k/IRA (start age 73)
2. Taxable accounts (capital gains rates, harvest losses)
3. Tax-deferred (Traditional 401k/IRA) — fill low brackets
4. Roth (last, lets it grow tax-free longest)

Roth conversion ladder between retirement and age 73: Fill 12-22% brackets with Trad → Roth conversions to reduce future RMDs.

# Retirement Readiness Analysis
**Prepared:** [Date]
**Current Age:** XX | **Target Retirement Age:** XX | **Years to Retirement:** XX

## Executive Summary
- **Retirement Score:** XX/100
- **Required Nest Egg (today's $):** $X,XXX,XXX
- **Required Nest Egg (future $):** $X,XXX,XXX
- **Projected Nest Egg (moderate):** $X,XXX,XXX
- **Gap:** $X,XXX,XXX
- **Required Monthly Contribution to Close Gap:** $X,XXX
- **Probability of Success at Current Trajectory:** XX%
- **Verdict:** ✅ On track / ⚠️ Behind / 🚨 Critical gap

## Inputs Summary
| Item | Value |
|------|-------|
| Current age | XX |
| Target retirement age | XX |
| Current retirement assets | $X |
| Annual contribution (you + employer) | $X |
| Expected annual spending in retirement | $X (today's $) |
| Expected Social Security | $X/yr at age XX |
| Pension | $X/yr |

## Required Nest Egg (3 Methods)

| Method | Today's $ | Future $ (at retirement) |
|--------|-----------|--------------------------|
| 25x Annual Spending | $X | $X |
| Spending - SS - Pension × 25 | $X | $X |
| Custom (with assumptions) | $X | $X |

## Projection Scenarios

| Scenario | Real Return | Nest Egg at Retirement | Years Lasts (4% withdrawal) |
|----------|-------------|------------------------|------------------------------|
| Conservative | 5% | $X | XX years |
| Moderate | 6% | $X | XX years |
| Aggressive | 7% | $X | XX years |

## Year-by-Year Projection Table

| Age | Year | Annual Contribution | Balance (Moderate) | Real Income at 4% |
|-----|------|---------------------|--------------------|--------------------|
| Current | YYYY | $X | $X | $X |
| ... | | | | |
| Retirement | YYYY | $0 | $X | $X |
| 75 | YYYY | $0 | $X | $X |
| 85 | YYYY | $0 | $X | $X |

## Monte Carlo Outcome Range

| Percentile | Nest Egg | Status |
|------------|----------|--------|
| 90th (great markets) | $X | Excellent |
| 50th (median) | $X | Base case |
| 10th (poor markets) | $X | Risk scenario |

**Probability of meeting goal:** XX%

## Gap Analysis & Required Action

Current trajectory falls short by $X,XXX,XXX.
To close the gap, ONE of these is needed:
- **Option A**: Increase contributions by $X/month (total: $X/month)
- **Option B**: Delay retirement by X years (to age XX)
- **Option C**: Reduce retirement spending by $X/yr (to $X/yr)
- **Option D**: Higher returns via more equity exposure (if risk tolerance allows)
- **Combination**: Most realistic mix

## Contribution Optimization Stack

Follow this order each year:
1. **401k to employer match** (free money — capture 100%)
2. **HSA max** ($X/yr if HDHP) — triple tax advantage
3. **Roth IRA max** ($X/yr; $X if 50+) — if income allows
4. **401k to max** ($X/yr; $X if 50+)
5. **Backdoor Roth** if income too high for direct Roth
6. **Mega Backdoor Roth** if plan allows (after-tax 401k → Roth)
7. **Taxable brokerage** with tax-efficient index funds

## Asset Allocation Recommendation

**Current age (XX):**
- Stocks: XX% ([XX% US, XX% international])
- Bonds: XX%
- Cash: XX%

**Glidepath to age 65:**
- Reduce stocks by ~1% per year until age 65
- Build "bond tent" 5-10 years pre-retirement to protect against sequence risk
- At age 65: 55/35/10 stock/bond/cash

## Social Security Optimization

| Claim Age | Monthly Benefit | Annual | Lifetime (to age 85) |
|-----------|-----------------|--------|----------------------|
| 62 | $X | $X | $X |
| 67 (FRA) | $X | $X | $X |
| 70 | $X | $X | $X |

**Recommendation:** [Age based on health, longevity, cash needs]
**Reasoning:** [breakeven analysis + family longevity + spousal coordination]

## Healthcare Cost Plan
- Pre-65 (ages XX-65): [ACA / COBRA / retiree plan] estimated $X/month
- Post-65: Medicare Parts A/B/D + Medigap estimated $X/month
- Total retirement healthcare reserve needed: $XXX,XXX (today's $)
- HSA contribution priority: $X/year currently → max to $X/year

## Withdrawal Sequence Plan (Ages 65-95)

| Age | RMDs | Taxable | Trad 401k/IRA | Roth | Total Withdrawal |
|-----|------|---------|---------------|------|------------------|
| 65-72 | $0 | $X | $X | $0 | $X |
| 73-80 | $X | $X | $X | $0 | $X |
| 80+ | $X | $0 | $X | $X | $X |

**Roth Conversion Ladder Plan:** Convert $X/yr between ages XX-72 to fill the 22% bracket and reduce future RMDs.
