Investment planning calculator

Retirement investment calculator for Roth, 401(k), IRA and brokerage planning

FutureFolio is built for DIY retirement planning and helps you project growth across Roth, 401(k), IRA, and taxable brokerage accounts, compare planning scenarios, and estimate how portfolio balances may support retirement income.

Built for DIY investors who want fast scenario comparison, contribution planning, and retirement income visibility.
Planning assumptions: projections depend on the return, contribution, time horizon, and withdrawal assumptions you enter. Results are estimates for planning, not guarantees or tax advice.

About FutureFolio

FutureFolio is a retirement planning calculator built to help investors see how different account types may grow over time and how those balances could translate into future retirement income. Instead of focusing on a single ending number, it helps you compare assumptions across tax-deferred, tax-free, and taxable brokerage accounts so you can plan with more context.

Built for scenario planning

Test contribution changes, return assumptions, and time horizons without rebuilding your whole plan from scratch.

Designed for real households

Use the tool to connect balances, compounding, and withdrawal assumptions to practical retirement goals.

Why investors use it

Many retirement calculators hide account structure or make it hard to compare scenarios clearly. FutureFolio keeps each tax bucket visible so you can understand whether your plan depends more on new savings, long-term growth, or withdrawal assumptions.

See account structure clearly

Keep Roth, traditional, and taxable balances separated so tax treatment stays visible during planning.

Compare outcomes faster

Review conservative, base, and aggressive cases side by side to understand the range of possible outcomes.

FAQ: how to use the calculator

What information should I enter first?

Start with your current balances for each account bucket, then add annual contributions, expected return assumptions, contribution growth, and the number of years you want to project.

How do I compare different outcomes?

Build a base case first, then create more conservative and more aggressive scenarios by changing savings rates, expected returns, or retirement timing. Comparing multiple cases makes it easier to see how sensitive your plan is to each assumption.

What should I look at besides the final balance?

Pay attention to how much of the projected result comes from contributions versus investment gains and how the final portfolio may translate into retirement income. Those views can be more useful than a single ending balance.

How can I use this for retirement planning?

Use the calculator to test whether your current savings path, expected growth, and withdrawal assumptions are likely to support your target income. Then adjust contributions, timeline, or return assumptions to see what changes improve the result.
