Buyer's guide
How to choose a 401(k) calculator
If your main goal is to see how personal contributions and an employer match grow over time, Bankrate's tool gets you results fastest. If you already have a 401(k) balance or want to test how raising your contribution rate affects the final total, NerdWallet's calculator handles those variables without needing a separate spreadsheet.
Questions
401(k) Calculator FAQ
- Can I use these calculators if I don't know my exact rate of return?
- Both calculators ask for an expected annual return; you can input a custom number or choose a common range to test various outcomes.
- Do these tools factor in inflation or tax effects?
- Bankrate's calculator has an inflation rate field; NerdWallet's does not advertise inflation modeling. Neither tool provides an after-tax projection.
- Which calculator is faster to use if I just want a rough number?
- Bankrate requires fewer data points, making it the faster option for a quick estimate.
- Can I compare multiple scenarios side-by-side in these tools?
- Both calculators process one set of inputs at a time; there is no mentioned feature to compare multiple scenarios simultaneously.
- Do I need to create an account to use either calculator?
- Both are usable without creating an account, though NerdWallet's page notes advertising partners that compensate the site.
