Sets a weekly allowance from a child's age, splits it into save, give and spend, and shows how long a savings goal will take.
The Pocket Money Calculator sets a weekly allowance from a child's age, splits it into save, give and spend, and shows how long a savings goal will take. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.
| Common convention | One unit per year of age, weekly |
|---|---|
| A 10-year-old | 10 a week on that rule |
| Save-give-spend | A widely used three-jar split |
| What matters most | Predictable and paid on time |
This tool uses weekly amount = a flat base + one unit per year of age + any chore bonus. The save, give and spend shares are then taken off the weekly figure, and the goal is divided by the weekly saving. Every intermediate value is shown on screen, so the result can be checked by hand.
The per-year-of-age rule is a convention with no research behind it, and it says nothing about what the allowance is meant to cover. An amount that includes school lunches and bus fares is a completely different number from one that is purely discretionary — decide that first, then use this for the shape.
