How it works
Aunt Rosa shares a handy rule of thumb called fifty, thirty, twenty. Think of ten blocks, split into five, three and two.
On 100 coins that is 50 for needs, like food, a home and the bus, 30 for wants, like fun, treats and presents, and 20 for saving. 50 + 30 + 20 = 100.
A rule of thumb is a quick guide, not a law. No one split fits everyone: some families need more for needs, and others save more.
The rule shrinks to fit any month. On Mina's 40 coins a block is 4 coins: 20 for needs, 12 for wants and 8 for saving.
