Retirement Calculator
Project your retirement savings with compound growth.
👵 Combines compound growth on current savings with regular contributions. Start early — time matters more than amount.
What Is This Tool?
This calculator projects how much you'll have saved by retirement, combining the compound growth on your current savings with regular monthly contributions. It's a powerful motivator — the numbers often surprise people.
The 4% Rule
A common guideline: you can withdraw 4% of your retirement savings each year with low risk of running out. To retire on $60,000/year of investment income, you'd need about $1.5 million saved ($60,000 ÷ 0.04).
The Power of Starting Early
Time matters more than amount. Someone who saves $500/month from age 25 to 35 (then stops) often ends up with more than someone who saves $500/month from age 35 to 65. The early saver's money has 30 extra years to compound.
Realistic Return Rates
- Aggressive (mostly stocks): ~7% after inflation — volatile but high long-term
- Balanced (stocks + bonds): ~5% after inflation
- Conservative (mostly bonds): ~3% after inflation
- Cash savings: ~0-1% after inflation — barely keeps up
Frequently Asked Questions
How much do I need to retire?
A common rule is 25× your annual expenses (the inverse of the 4% rule). For $40,000/year expenses, aim for $1 million. Many financial advisors now suggest 30× to be safe given longer lifespans.
