Answer
Answer key: Roth IRA worksheet
Calcapedia 1. Roth IRA at age 50: $12,415.64
Start with the 2026 IRA limit for people under 50
Your income (MAGI) is at or above $10,000.00, the top of the phase-out range, so you can't put money in a Roth directly
So this is your 2026 Roth IRA limit
This year you put in your planned amount or the limit, whichever is smaller
Each year the balance earns its return, then that year's money is added
Repeat that for 15 years to get the balance when you retire
Find the growth: the final balance minus what you started with and what you put in
Compare with a taxable account. If 15% of the growth is taxed each year, the money grows at only 5.95% a year, so you'd end up with this much less
2. Roth IRA at age 55: $809,326.79
Start with the 2026 IRA limit for people under 50
Your income (MAGI) is at or below $242,000.00, where the phase-out starts, so you can put in the full amount

This year you put in your planned amount or the limit, whichever is smaller
Each year the balance earns its return, then that year's money is added
Repeat that for 25 years to get the balance when you retire
Find the growth: the final balance minus what you started with and what you put in
