About this tool

Enter your current balance, how much you add each year, the years and the expected return. The calculator shows what you put in, the growth and the final value. Qualified Roth withdrawals are free of federal tax. Figures are for the 2026 tax year and can change. A guide only, check irs.gov or a tax professional.

Why Roth

You pay tax on the money before you contribute, but qualified withdrawals in retirement, including all growth, are free of federal income tax. The tool shows a rough 15 percent tax saved on the growth as a guide.

Limits

The 2026 contribution limit is $7,500, or $8,600 at 50 or older, and it phases out at higher incomes. You must have earned income. Withdrawals of earnings are tax free after age 59½ and five years.

Example

$7,500 a year for 30 years at 7 percent grows to about $708,000, from $225,000 contributed.

計算示例

With the boxes at their starting values (Current balance ($): 0; Contribution per year ($): 7500; Years to grow: 30; Expected return per year (%): 7), the tool shows: Total you put in ($): 225,000; Growth ($): 483,456; Rough tax saved on growth at 15% ($): 72,518; Final balance ($): 708,456. Change any box to see your own numbers. The result updates as you type, and nothing leaves your browser.

在相信結果之前先檢查每一個輸入項，因為一個錯誤的數字就會改變整個答案。請使用工資單、賬單、證書或合同上的準確數字，並記下計算日期。稅率、門檻和規則會不時變化，因此對於稅費和法律事務，請將結果視為估算，並與本頁註明的官方來源核對。您可以嘗試任意多個方案；不會儲存或傳送任何內容，重新整理頁面會清空輸入。
