Takes about two minutes. The first thing you'll do is set up your kid's page.

Already set up? Kid sign-in →

Turn their allowance into a teaching tool.

1. Set up their account.

Set each kid's allowance, schedule, interest rate, and a giving match.

2. Let them sign in.

Income and interest update automatically.

3. Approve virtual withdrawals.

They send a request, you approve it, and you hand over the cash. That's the only time your wallet opens — allowance and interest just land in the ledger. No real money on the site.

Three paths to financial wisdom.

The power of compound interest

Set the rate and they watch $50 become $51.25, then $52.52. Hearing "money grows" is one thing; watching your own balance do it is another.

The future cost of spending today

Before any withdrawal, they see two future possibilities and learn what it costs them later, not only right now.

Take $20 today

You'd have $99.77.

Your savings goal for the bike moves Aug 4 → Aug 25.

This $20 becomes ● $23 in a year…

…and ● $59 by eighteen.

The beauty of giving

Determine a donation match and incentivize charitable giving. When they give, it multiplies.

Virtual ledger. Real money. Low stakes.

The power of money is something most people don't encounter until they are thrust into the real world. With an allowance powered by TrezzerChest, kids can make real decisions with money and discover the consequences firsthand, preparing them for the future.
