Errand Money Isn't Allowance: Keep the Change Separate
By Erik Nilsen · Kroni6 min read
If your child takes money to buy something the family needs, that money is still yours. You own what they buy, and the change comes back to you. Your child only earns something from the errand if you agree on a separate reward. That reward is its own agreement, and it shouldn't quietly come out of the change.
This can sound strict, but it makes things easier day to day. Your child knows what they're responsible for. You know where the money is. And nobody has to guess whether "the rest" was meant as pay.
Three amounts to keep apart
A small family errand involves three different pots of money:
- The money you hand over. This belongs to the household. Your child just holds it until the shopping is done.
- The change. Whatever is left after the purchase. It still belongs to the household and goes back to you.
- An agreed reward, if there is one. It only exists if you agreed on it beforehand, and you pay it as a separate amount.
Buying what the family needs is an adult responsibility. Your child helps carry out the errand, but their own money doesn't pay for the milk or the bread.
Before you go: write down the errand
A good errand starts with a clear order. Write it on a note or in your phone:
- What to buy. "One lemon and one packet of dry yeast."
- How much money your child takes. "$20."
- Spending limit. "Don't spend more than $20."
- What to do if an item is missing. "Ask me before you pick something else."
That last point is easy to forget. If the yeast is sold out and your child grabs a pricier brand, or buys something else entirely, it's suddenly unclear who pays. The rule "ask before you swap" clears that up.
This is an errand with an adult nearby. You might stand next to your child at the register, wait by the exit, or walk the aisles together while your child holds the list and the money. How much your child can handle alone varies from child to child. Our list of what kids can do at home by age has ideas for adjusting tasks as you go.
A worked example
This is a made-up example. The amounts are for illustration only and are not a recommended rate.
Maya, 9, gets $20 to buy a lemon and a packet of yeast. Her mom waits by the register. The items cost $14 in total. Maya gets $6 in change and hands it to her mom when they walk out.
Before they left, Maya and her mom also agreed that Maya gets $2 for being in charge of the list, the money and the receipt. Mom pays that $2 separately. It does not come out of the $6 change.
| Adult's money given | Approved purchase | Change back to adult | Separate agreed reward for child |
|---|---|---|---|
| $20 | $14 | $6 | $2, if agreed separately |
The math that has to add up: $20 = $14 + $6. The reward isn't part of that equation, because it isn't part of the purchase.
Why not just say "keep the change"? You can agree on that if you like. But then the reward depends on prices. If lemons cost more, your child gets less. And if your child buys something cheaper than agreed to keep more, you're having a very different conversation. A fixed, separate amount keeps the errand and the reward apart.
After the errand: count it together
When you get home, do a quick check together:
- Put the receipt on the table.
- Count the change.
- Check that the receipt total plus the change equals what you handed over.
If it adds up, the errand is done. If it doesn't, count again and look at the receipt together before deciding anything. Maybe an item was scanned twice. Maybe a coin is still in a jacket pocket. Maybe the price at the register was different from the shelf tag. Looking for the explanation together works better than jumping to blame.

What belongs in your child's earnings?
Only what you agreed is your child's money. In the example, that's the $2. Not the $20, and not the $6.
If you use Kroni, you can add the errand as its own task with an agreed reward. Your child marks it done. If you chose to require approval, the amount waits for your approval; otherwise, it is added to the balance on completion. The shopping money and the change don't belong there, and Kroni doesn't handle payment at the store. When it's time to settle the reward in real money, you do that yourself with cash or a transfer, outside the app. When you pay out the virtual reward, record that payout once as a deduction from the available balance. A reward already handed over in cash should not also remain as money owed to your child.
If you didn't agree on a reward, the errand is simply ordinary family help. That's completely fine too.

How to start this week
- Pick one small errand where you come along, like one or two items for dinner.
- Decide beforehand whether there's a reward, and if so, how much.
- Write the errand on the note and have your child read it aloud before you leave.
- Count together when you get home, and add only the agreed reward to your child's earnings.
After a few rounds, the check becomes familiar for both of you. Your child learns which money they were only looking after and which money they earned.
Frequently asked questions
- Can my child keep the change as a reward?
- You can agree on that, but then the reward depends on what the items cost. A fixed amount you pay separately makes it clearer which money belongs to the household and which belongs to your child.
- What if the change doesn't match the receipt?
- Count again and look at the receipt together. There's often a simple explanation, like an item scanned twice, a price different from the shelf tag, or a coin left in a pocket. Talk it through before drawing any conclusions.
- Should the shopping money go into my child's balance in the app?
- No. Money for family purchases belongs to the household. Only a reward you agreed on beforehand belongs in your child's balance, and you pay it in real money outside the app.
