Estimate long-term retirement accumulation in a Roth IRA under contribution and return assumptions.
Overview
Roth IRAs can provide tax-advantaged growth and qualified tax-free withdrawals under rules.
This calculator projects account growth from balance and ongoing contributions.
It helps evaluate whether current savings pace matches retirement goals.
Use realistic return assumptions and contribution limits in planning.
Steps
Input total current account value.
Use expected yearly contribution amount.
Choose conservative annual growth assumption.
Select accumulation horizon length.
Review estimated retirement-age balance.
Math
FV = PV(1+r)^n + PMT[((1+r)^n - 1)/r]
Roth growth projection uses compounded current balance plus future value of annual contributions.
Worked cases
Apply future value projection with annual contributions.
Long-term growth can be substantial with consistent saving.
Re-run projection at higher annual PMT.
Higher annual contributions significantly boost final balance.
Stress test projection with reduced rate.
Conservative assumptions improve planning resilience.
