Key Inputs to Get Right
The most important numbers are usually the interest rate and the time horizon. Over years or decades, small rate differences compound into large dollar differences, so it's worth sanity-checking the rate against current market data before acting on any result.
Planning for Retirement
The earlier you start saving, the more compound interest works in your favor. Financial advisors often recommend saving 15% of your income for retirement.

Frequently Asked Questions
How much do I need to retire?
A common guideline is 25 times your annual expenses. If you spend $60,000/year, aim for $1.5 million. This assumes a 4% annual withdrawal rate. Adjust higher for early retirement or lower for more conservative spending.
When should I start saving for retirement?
As early as possible. Someone who starts investing $500/month at age 25 could have over $1 million by 60 (at 8% returns). Starting at 35 would require about $1,100/month to reach the same goal. Time is your biggest advantage.
