Allowance Split Calculator
Split any allowance into save, spend, and share jars by percent with dollar amounts.
What it does
Save, spend, share jars turn pocket money into a first budget. The rule is small: pick save and spend percents, and the share jar takes the rest, so every dollar has a job before it is touched.
The tool above takes the allowance plus save and spend percents. It returns dollars for save, spend, and share, so $20 at 50 and 30 reads as $10.00, $6.00, and $4.00.
This math fits one allowance payment with percent splits. It does not fit chore based pay per task, interest bearing youth accounts, or gifts earmarked for one jar only.
Financial education guidance frames the same habit: youth banking and Money Smart lessons start with dividing money on purpose, and consumer resources stress practicing with small real amounts first.
Tape the percents to the jars. When the split stays visible, the share jar survives the toy aisle.
How to use
- Enter the allowance payment amount.
- Enter save percent for the future jar.
- Enter spend percent for now spending.
- Read share percent as 100 minus both entries.
- Read all three dollar jars for the split.
- Rerun when allowance or percents change.
Formula
- allowance
- Payment amount split three ways.
- save %
- Percent reserved for the future.
- spend %
- Percent free for now spending.
Save plus spend must stay at or below 100. Zero allowance gives zero jars. The same percents scale to any pay frequency.
Worked example
Example: $20 at 50% save, 30% spend
Allowance 20, save 50%, spend 30%.
- Share: 100 - 50 - 30 = 20%.
- Save: 20 x 0.50 = $10.00.
- Spend: 20 x 0.30 = $6.00.
- Share: 20 x 0.20 = $4.00.
- Tool shows save $10.00, spend $6.00, share $4.00.
Reference table
| Split save/spend/share | Save | Spend | Share |
|---|---|---|---|
| 50 / 30 / 20 | $10.00 | $6.00 | $4.00 |
| 40 / 40 / 20 | $8.00 | $8.00 | $4.00 |
| 30 / 50 / 20 | $6.00 | $10.00 | $4.00 |
Limits
- Percent splits only. Per task chore pay needs its own lines.
- Ignores interest earned in youth savings accounts.
- Ignores gifts restricted to one jar.
- One payment per run. Weekly and monthly need separate runs.
Common mistakes
- Letting save plus spend top 100%.
- Splitting before setting the share percent.
- Moving share money to spend midweek silently.
- Using different percents each week without agreeing.
- Counting the same dollar in two jars.

Questions
How do save spend share jars work?
Pick save and spend percents. Share takes 100 minus both, and each jar gets allowance times its percent.
What is a good kid split?
Many families start 50 save, 30 spend, 20 share, then adjust with the child.
What if save plus spend top 100?
Lower one of them. The page rejects totals above 100%.
Does this work for monthly allowance?
