Retirement Planning: Building Your Future

How retirement planning works in practice

Retirement planning projects future income needs, savings growth, and withdrawal rates to ensure you can stop working without running out of money. It combines compound growth, inflation, and life expectancy.

The goal is not to memorize every term — it is to know which inputs matter and what outcome you are aiming for.

So what: When you can explain this in your own words, you are far less likely to accept a bad quote, fee, or assumption.

A real scenario worth running

Age 30, want $60,000/year in retirement at 65, 7% average return, already have $20,000 saved. Step by step: Target nest egg = $60,000 × 25 = $1,500,000 (4% rule) → Monthly SIP needed ≈ $850/month for 35 years at 7% → Without existing $20k: ≈ $900/month. Bottom line: Saving ~$850/month from age 30 to 65 at 7% return targets a $1.5M portfolio for $60k/year withdrawals.

So what: Plug your own numbers into the same logic before you decide.

How much do you need to retire?

Retirement planning answers three questions:

1. How much will I spend each year in retirement?
2. How large a portfolio funds that spending?
3. How much must I save now to reach that portfolio?

Most people underestimate #1 (healthcare, inflation) and overestimate investment returns. Conservative assumptions beat optimistic surprises.

So what: Run your own inputs before you commit — small changes in assumptions can shift the outcome sharply.

The 4% rule explained

Withdraw 4% of your portfolio in year one of retirement, then adjust for inflation each year. On a $1,000,000 portfolio, that's $40,000 in year one.

This rule comes from the Trinity Study — historical US market data showing 4% sustained 30-year retirements in most scenarios. It's a guideline, not a guarantee. Sequence-of-returns risk (bad market years early in retirement) can derail even large portfolios.

Safer variants

• 3–3.5% withdrawal rate for early retirees (40+ year horizon)
• 4% for traditional retirement at 65 with 30-year horizon
• Dynamic spending — reduce withdrawals in down years

So what: Run your own inputs before you commit — small changes in assumptions can shift the outcome sharply.

Building your retirement number

Subtract fixed income first: Social Security, pension, rental income reduce the portfolio gap.

Example: Need $70,000/year, Social Security provides $25,000 → portfolio must cover $45,000 → target ≈ $1,125,000 at 4%.

So what: Run your own inputs before you commit — small changes in assumptions can shift the outcome sharply.

Worked example: saving from age 30 to 65

Goal: $1,500,000 at 65. Assume 7% average annual return.

Starting 5 years earlier roughly halves the monthly burden. Time is the most powerful variable.

So what: Run your own inputs before you commit — small changes in assumptions can shift the outcome sharply.

Account priority order

1. Employer 401(k) match — free money; always take full match (typically 3–6% of salary)
2. Emergency fund — 3–6 months expenses in cash before aggressive investing
3. Roth IRA / traditional IRA — $7,000 limit (2026, under 50); tax-advantaged growth
4. Max 401(k) — $23,500 employee limit (2026); + $7,500 catch-up if 50+
5. HSA (if eligible) — triple tax advantage for healthcare
6. Taxable brokerage — after tax-advantaged accounts are maxed

So what: Run your own inputs before you commit — small changes in assumptions can shift the outcome sharply.

Inflation matters — real vs nominal

$60,000 of spending today requires roughly $97,000 in 20 years at 2.5% inflation. Retirement projections must inflate future spending, not use today's dollars.

Social Security COLA adjustments help but may not fully match personal spending inflation (especially healthcare).

So what: Run your own inputs before you commit — small changes in assumptions can shift the outcome sharply.

Asset allocation by age

Target-date funds automate this glide path.

So what: Run your own inputs before you commit — small changes in assumptions can shift the outcome sharply.

Healthcare before Medicare (US)

If retiring before 65, budget $500–$1,500+/month per person for ACA marketplace insurance — often the largest surprise expense. Include this in pre-65 retirement spending models.

So what: Run your own inputs before you commit — small changes in assumptions can shift the outcome sharply.

Common mistakes

1. The 4% rule: withdraw ~4% of portfolio annually in retirement — this quietly costs you over time.
2. Start early — compounding needs decades to work..
3. Factor inflation: $50k today ≠ $50k in 30 years — this quietly costs you over time.
4. Include employer 401(k) match — it's free money..
5. Diversify across stocks, bonds, and tax-advantaged accounts — this quietly costs you over time.
