Retirement Planner

Why does inflation matter so much for retirement planning?

Inflation quietly shrinks what your money can buy. At just 3% annual inflation, a monthly expense of $4,000 today grows to roughly $10,800 in 35 years — nearly triple, without you spending a cent more in real terms. Retirement plans that ignore inflation almost always fall short, because they size the corpus for today's cost of living instead of tomorrow's.

What is the 4% withdrawal rule?

The 4% rule is a rough guideline suggesting you can withdraw 4% of your retirement corpus in the first year, then adjust that amount for inflation each year after, without running out of money over a 25-30 year retirement. It implies a corpus of about 25 times your annual expenses. It's a starting point, not a guarantee — actual safe withdrawal rates depend on market returns, retirement length, and how your portfolio is invested.

What is sequence-of-returns risk?

Sequence-of-returns risk is the danger of hitting poor market returns in the years right before or after you retire. Two retirees can earn the same average return over 30 years, but if one hits a market crash in year one of retirement while withdrawing money, their corpus can be permanently depleted faster than someone who saw the crash later. This is why many retirees shift toward more conservative, lower-volatility investments as retirement approaches.

Does starting early really make that much difference?

Yes — compounding rewards time more than almost any other factor. Someone who starts saving $300/month at age 25 and stops at 35 (investing for just 10 years) can end up with more at 65 than someone who saves $300/month from 35 to 65 (25 years), purely because the first saver's money compounded for longer. Every year you delay costs disproportionately more to make up later.

Why use a different return rate before and after retirement?

Before retirement, you're typically investing for growth — often in equities — which historically returns more but swings more in value. After retirement, most people shift toward capital preservation and steady income, accepting a lower but more predictable return so a market downturn doesn't wipe out savings you're actively withdrawing from. That's why this calculator lets you set pre-retirement and post-retirement return rates separately.

Do I need to plan separately for healthcare costs?

Healthcare costs typically rise faster than general inflation, often by 1-3 percentage points more per year, and tend to increase sharply after age 70. A retirement plan that only inflates your general living expenses can understate what you'll actually need. Many planners recommend building a separate healthcare or medical emergency buffer on top of the core retirement corpus.

Is a pension or social security enough on its own?

For most people, no. Government or employer pensions are designed to supplement personal savings, not replace them, and typically replace only 30-45% of pre-retirement income. Treat any pension or social security payout as one leg of the stool — your personal corpus and investments need to cover the rest.

What happens if I retire earlier than planned?

Retiring early means fewer years of pre-retirement compounding and more years the corpus has to last, so it must work far harder. Retiring 5 years early can require 20-30% more corpus, since you're both cutting off contributions sooner and stretching withdrawals over a longer post-retirement horizon.
