Pocket money tracker
Track your weekly allowance, your spending, and your savings rate — simple numbers, clear feedback.
Calculator personalLogic updated April 2026
This calculator helps you keep track of how much pocket money you've received over a period of weeks and how much you've spent — so you can see your savings rate and notice patterns. It's a simple way to understand where your money is going and how often you're saving versus spending.
How this is calculated
Formula
totalReceived = weeklyAllowance × weeks ; totalSaved = totalReceived − amountSpent ; savingsRate = totalSaved / totalReceived × 100Step-by-step
- Multiply your weekly allowance by the number of weeks to find your total received
- Subtract the amount you've spent to find your total saved
- If you spent more than you received, the calculator flags an overspend so you can adjust
- Calculate the savings rate: total saved divided by total received, expressed as a percentage
- Build a week-by-week schedule that distributes your spending evenly across the period (the real pattern is usually lumpier)
- Calculate average weekly savings so you can see your typical pace
- Rounding mode
- ROUND_HALF_UP
- Precision
- 20-digit internal precision (Decimal.js), rounded to 2 decimal places for display

Assumptions & limitations
What this calculator assumes
- Allowance is received once per week
- Spending is distributed evenly across the tracked weeks
- Savings cannot go below zero in the schedule — overspend is surfaced separately
- Week horizon is capped at 260 weeks (5 years)
What this calculator doesn’t account for
- Doesn't track individual purchases — just a total spending figure
- Doesn't identify what you spent on (try writing it down separately)
- Doesn't model weeks when you got extra (gifts, helping with chores) — add those to allowance manually
- Spreads spending evenly even if real spending was lumpy
- Doesn't include interest from a savings account
Worked example
A child has been getting $10 a week for 12 weeks and has spent $80 over that period.
| Input | Value |
|---|---|
| Weekly allowance | $10 |
| Weeks tracked | 12 |
| Amount spent | $80 |
Total received: $120 — Total saved: $40 — Savings rate: 33% — Average weekly saving: $3.33
$10 × 12 = $120 received over 12 weeks. Spent $80, so saved $40 — a 33% savings rate. That means for every dollar received, 33 cents stayed in the bank. If the goal is to save more, the levers are: get more (extra chores or a job), spend less, or both. The average weekly saving of $3.33 is the rate at which the savings balance is actually growing.
Frequently asked questions
Why should I track my pocket money?
Because tracking is the first step to understanding. When you write down what you spend, you start to notice patterns — small purchases that add up, things you don't really need, or items that gave you the best value. Most adults who are great with money started tracking when they were young. It doesn't have to be fancy: a notebook, a phone note, or this calculator all work.
What should I write down?
Just two things: how much you got and how much you spent. If you want more detail, add what you spent it on (a snack, a game, a gift). Over a few weeks you'll see your habits clearly. Don't try to track every cent at first — start with weekly totals, then add more detail if it's useful. Tracking is most powerful when you actually look at the numbers later.
How do I know if I'm spending too much?
Check your savings rate (the percentage saved). A rate of 0% means everything you got got spent — there's no buffer for emergencies or goals. A rate of 50%+ is great for kids saving for things like bikes, games, or future plans. There's no perfect number — but going from 0% to even 20% makes a huge difference over a year. Compare your rate now vs a few weeks from now to see if you're improving.
What patterns will I notice?
Most kids notice three things after tracking for a month: (1) small purchases ($2 here, $5 there) add up to surprising totals, (2) certain weeks have much more spending than others (often birthday weeks or special events), and (3) the things you most wanted to buy aren't always the things that gave you the most enjoyment. Tracking turns 'where did my money go?' into a clear answer.
What if I spent more than I got?
The calculator flags this as an overspend. It usually means you got extra money from somewhere (a gift, leftover from before) and it's not in your allowance figure. Add the extra money to your starting balance or a separate income figure. If you really did spend more than you received, that means dipping into earlier savings — an important moment to notice, because it shows your saved money is being used up.
