Planning for retirement requires answering three key questions: How much do I need? How much should I save each month? How long will my money last? This calculator answers all three. The widely-used 4% rule suggests your retirement nest egg should equal 25× your annual expenses — because a 4% annual...

Enter your current age and target retirement age, your current retirement savings balance, and your expected annual investment return (7% is a common long-term estimate for a diversified portfolio).
Enter your expected annual retirement expenses — what you plan to spend each year in retirement. The calculator uses the 4% rule to show your nest egg target (expenses × 25).
Enter how much you are currently saving per month. The calculator compares your projected balance against your nest egg target and tells you if you are on track or how much more you need to save.
The drawdown section shows how long your savings will last given your withdrawal rate and portfolio return in retirement. Enter a post-retirement return (often lower, 4–5%, reflecting a more conservative portfolio).
James is 35, has $50,000 saved, and plans to retire at 65. He expects $60,000/year in retirement expenses. Nest egg target (4% rule): $60,000 × 25 = $1,500,000. He is currently saving $1,000/month at 7% annual return. Projected balance at 65: $1,096,343 — he is $403,657 short of his target. To reach $1,500,000 in 30 years at 7%, he needs to save $1,479/month total. He currently saves $1,000, so he needs an additional $479/month. At 5% post-retirement return, $1,500,000 with $60,000/year withdrawals would last approximately 52 years.
| METRIC | FORMULA | NOTES |
|---|---|---|
| Nest Egg Target | Annual Expenses × 25 | 4% rule — 30+ year retirement |
| Projected Balance | PV×(1+r)^n + PMT×[((1+r)^n−1)/r] | Compound growth + contributions |
| Monthly Needed | PMT = FV × r / ((1+r)^n − 1) | Reverse future value annuity |
| Withdrawal Rate | Annual Withdrawal / Nest Egg × 100 | 4% is standard safe withdrawal |
| Money Duration | Month-by-month: B = B×(1+r) − withdrawal | Until balance reaches zero |
