Savings & Retirement calculators
Saving for retirement comes down to three things you control: how much you put in, how long it grows, and how much of it taxes take. These calculators show all three. See how compound interest turns regular deposits into a large balance, what your 401(k) could be worth with your employer’s match, and how the 2026 contribution limits and catch-ups apply at your age.
Once you retire, the rules turn around: the IRS requires withdrawals from traditional accounts from age 73 or 75, and each one is taxable income that can affect your Medicare premiums. The RMD calculator shows what you must take and when.

- Saving for a child? The Trump Account calculator projects what the new children’s accounts, with their $1,000 government deposit, could grow to by 18.

Time does most of the work
At a 7% yearly return, money doubles about every ten years. That makes the first dollars you save the most valuable ones: a deposit made at 25 can grow to several times what the same deposit made at 45 will. Get your full employer match first, raise your contribution rate a little each year, keep fees low, and let compounding do the rest.
