The allowance app where you're the bank.
Teach real financial wisdom with a virtual ledger.
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.
Leave it
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.
What makes it different.
- Fix anything, any date: the ledger recomputes itself, so every line always adds up.
- Whatever rate you set, their page shows it plainly. A real bank pays about 4%; most families here set more, so the lesson is visible.
- Every entry explains itself, and rules changes go on the record too.
Built by a dad. Free forever.
I made this for my own kids. No premium tier, no card to connect.
