Trump Account Calculator: How Much Will a Child Account Be Worth at 18?

In October 2026, over 60 million American children were auto-enrolled into federal child savings accounts (popularly referred to as "Trump Accounts"). Designed to provide the next generation with a financial safety net upon reaching adulthood, the cornerstone of the initiative is an automatic $1,000 federal seed investment granted to an estimated 14.4 million babies born between January 1, 2025, and December 31, 2028.

For millions of parents and grandparents, the central question is simple: **How much will this account actually be worth when my child turns 18?**

Who Qualifies for the $1,000 Federal Seed?

To receive the initial $1,000 government deposit, a child must satisfy three specific statutory criteria:

1. **Birth Date Window**: Born between January 1, 2025, and December 31, 2028.

2. **Valid SSN**: The child must possess a verified United States Social Security Number.

3. **Lawful Citizenship**: Must be a verified US citizen at the time of enrollment.

Children born before 2025 who were enrolled on October 1, 2026 are eligible for family contributions and tax-advantaged compound growth, but do not receive the retroactive $1,000 seed deposit.

Annual Contribution Limits & Who Can Deposit

The federal framework allows parents, grandparents, extended family, legal guardians, and approved charitable sponsors to contribute up to an aggregate maximum of **$5,000 per calendar year** ($416.66 per month) per child. Contributions grow sheltered from annual federal income taxes until legal adulthood at age 18.

Projected Values at Age 18: Compound Growth Scenarios

The power of compound interest over an 18-year investment horizon transforms relatively modest monthly deposits into substantial wealth. Assuming historical diversified market returns (a balanced 7% real return or a 10% nominal S&P 500 average):

- **Scenario A: Seed Only ($0/month)**: With no parental deposits, the $1,000 seed compounds to approximately **$3,380** at 7% return, or **$5,560** at 10% return.

- **Scenario B: $50/month ($600/year)**: Adding just $50 each month yields **$23,780** (at 7%) and **$35,590** (at 10%).

- **Scenario C: $100/month ($1,200/year)**: A $100 monthly commitment accumulates to **$44,180** (at 7%) and **$65,620** (at 10%). Total family deposits: $21,600.

- **Scenario D: Max Annual Contribution ($416.66/month or $5,000/year)**: Maxing out the allowable limit produces an astounding **$173,380** (at 7%) or **$261,350** (at 10%). Family deposits: $90,000. Interest earned: up to $171,350.

Qualified Withdrawal Rules at Age 18

Unlike a traditional custodial account where an 18-year-old can withdraw cash for arbitrary spending, federal child savings accounts are intended for foundational life milestones. Permissible qualified distributions include:

- Higher education tuition, room, board, and textbooks at accredited universities or vocational trade schools.

- Down payment toward the purchase of a first primary residential home.

- Qualified startup capital for establishing a registered US business enterprise.

- Direct rollover into a qualified Roth retirement account.

Trump Account vs. 529 College Savings Plan vs. UTMA/UGMA

How does this account compare to existing options? A **529 Plan** is restricted to educational expenses, whereas a Trump Account allows first-time home buying and small business capital. A **Custodial UTMA/UGMA Account** offers complete spending flexibility at the age of majority (18 or 21) but does not provide a $1,000 federal seed and is taxed annually under "kiddie tax" rules.
