Plan by person, account by account
Add a person, then their accounts: Roth IRA, pre-tax 401(k) or brokerage.
Each scenario lives under the account it belongs to, so a household’s plan stays organized the way the accounts really are.
Investment growth planner for iPhone
See what your savings plan really leaves you to spend.
Plan by person, account by account. Compound separates the balance on paper, the tax owed when you withdraw, and the amount that is spendable. No account, nothing uploaded.
Free. Compound Pro $4.99 once. Estimates, not financial advice.
How it works
A short tutorial runs the first time you open the app, and you can skip it. Here is the short version.
Your assumptions, your numbers
Enter contributions, escalating contributions, fees and tax rates.
Every figure Compound shows comes from the numbers you put in. It does not guess at your rates or promise a return.
Balance, tax and spendable
Three different numbers, kept apart: the balance on paper, the estimated tax on withdrawal, and what is spendable.
A balance is not what you get to spend. Compound shows the gap so you can plan with the number that matters.
Share or back up as a file
Share a person’s whole plan as a file, or back up and restore from Settings.
A shared plan carries the fee, escalating contribution, account type and tax rates. Backups go to a file you choose; nothing is uploaded.

What Compound is not
Compound is a planner, not an adviser. It gives estimates based on the numbers you enter. It is not financial, tax or investment advice, it does not promise any return, and it does not link to your bank or ask you to create an account.
