Interest on Save
You pay your kid interest so they see saving grow.
What it is
Every week or month you pay a small percentage of what's in their Save jar. It's worked out on the average balance over the period, so it rewards keeping money in, not a quick deposit the day before.
Why it helps your kid
Watching money grow by itself is the most powerful saving lesson there is. Real banks pay too little for kids to notice; you can pay enough to see.
Where to find it
Kids tab → your kid → Allowance, split & interest.
How to do it
- Set the rate and choose weekly (on payday) or monthly.
- Optional: a second tier, e.g. 10% on the first $200 and 2% above that, so a big balance doesn't get expensive.
- The page shows about how much it'll cost you per period and per year.
- Interest is paid automatically from the family pot.
What your kid sees
"Money grew" messages, lifetime interest on Home, and a What-if calculator showing how their money would grow.
Questions parents ask
Isn't 5% a month a lot?
It's meant to be visible. 5% a month on $40 is $2. Use a second tier to keep it affordable as they save more.
