How this calculator works
This retirement calculator uses the compound interest formula to project your savings growth:
A = P(1 + r/n)^(nt) + PMT × [((1 + r/n)^(nt) - 1) / (r/n)]
Where P = initial savings, r = 7% annual return, n = 12 (monthly compounding), t = years to retirement, PMT = $500/month contribution.
The 4% rule (Trinity Study, 1998) suggests you can safely withdraw 4% of your retirement savings annually. This means you need 25× your annual expenses saved.
Frequently asked questions
How much will I have at 65 if I start at age 45?
With $100,000 saved and $500/month contributions at 7% annual return, you would have approximately $664,337 at age 65.
What is the 4% rule?
The 4% rule suggests you can withdraw 4% of your retirement savings annually without running out of money over a 30-year retirement. This means you need 25 times your annual expenses saved.
