Frequently Asked Questions

How much money do I need to retire?

A common guideline is the "25x rule" — save 25 times your annual expenses. If you spend $50,000/year, aim for $1.25 million. However, this varies based on your retirement age, expected Social Security benefits, healthcare costs, and lifestyle goals. Our calculator factors in all of these variables using Monte Carlo simulations to give you a personalized target.

What is a Monte Carlo retirement simulation?

Monte Carlo simulation runs 1,000+ scenarios using randomized market returns based on historical data. Instead of assuming a fixed 7% return every year, it tests what happens in good years, bad years, and crash years. This gives you a "probability of success" — for example, "87% chance your money lasts to age 95." It's far more realistic than simple compound interest calculators.

What is the 4% rule and should I follow it?

The 4% rule (from the 1994 Trinity Study) says you can withdraw 4% of your portfolio in year one, then adjust for inflation each year, and your money should last 30 years. It works well as a starting point, but has limitations: it assumes a 30-year retirement, doesn't account for variable spending, and was based on historical US market data. Consider adjusting to 3.5% for early retirement or if you want extra safety margin.

How does inflation affect my retirement savings?

Inflation erodes purchasing power over time. At 3% average inflation, $1 million today will only buy $412,000 worth of goods in 30 years. Our calculator automatically adjusts your projections for inflation, showing both nominal and real (inflation-adjusted) values. This is why it's critical to invest in growth assets — cash savings lose value to inflation every year.

When should I start saving for retirement?

As early as possible. Starting at age 25 with $500/month at 7% returns gives you $1.2 million by 65. Waiting until 35 to save the same amount yields only $567,000 — less than half. This is the power of compound interest. But if you're starting late, don't panic: catch-up contributions ($7,500 extra in 401(k) after age 50), aggressive saving, and delayed retirement can close the gap significantly.

Should I use a Roth or Traditional retirement account?

It depends on your current vs. future tax bracket. Traditional 401(k)/IRA gives you a tax deduction now but you pay taxes on withdrawals. Roth accounts use after-tax money but withdrawals are tax-free. General rule: if you're in a lower tax bracket now than you expect in retirement, choose Roth. If you're in a high bracket now, traditional may save more. Many advisors recommend having both for tax diversification in retirement.
