About the Kids Allowance Calculator
This kids allowance calculator turns the popular “a dollar per week for each year of age” rule into a concrete number for your family. Enter your child’s age and the amount per year of age you are comfortable with, choose how often you pay, and it shows the allowance per payday, per year, and how it splits between spending, saving and giving.
It is meant for parents who want a consistent, explainable allowance rather than ad-hoc handouts, and for families using the three-jar method to teach money habits. Adjust the rate up if the allowance must cover school lunches, clothes or phone costs, or down if it is purely pocket money.
The savings projection assumes the saved share is set aside every year until age 18 at the current rate, with an optional parent match on savings to reward saving. It ignores interest and future raises, so treat it as a conservative floor — most families raise the allowance each birthday, which the per-age rule does automatically.
With the default inputs, the allowance per payday is $10.00. Change any value above to recalculate instantly.

Formula and method
The weekly allowance is the child’s age multiplied by the amount you pay per year of age, so it rises automatically on every birthday. Biweekly pay is two weeks’ worth, and monthly pay converts 52 weeks into 12 equal months (weekly × 52 ÷ 12 ≈ weekly × 4.33) so no month is short-changed.
Each payday is split by the save and give percentages; the remainder goes to spending. The savings projection multiplies the yearly saved amount (plus any parent match) by the number of years left until 18. It deliberately ignores interest and the yearly age-based raise, so the real total is usually higher.

Worked examples
10-year-old, $1 per year of age, weekly
Ten years × $1 gives $10 a week, or $520 a year. With 40% saved and 10% given, each payday puts $5 in spend, $4 in save and $1 in give. Saving $208 a year for the 8 years until 18 adds up to $1,664.
14-year-old paid monthly with a 50% savings match
A 14-year-old earns $14 a week; monthly that is $14 × 52 ÷ 12 ≈ $60.67. Half ($30.33) is saved. Saving $364 a year plus a 50% parent match is $546 a year, so four years to 18 builds $2,184.
7-year-old at 50¢ per year, every two weeks
At $0.50 per year of age a 7-year-old earns $3.50 a week, paid as $7 every two weeks. With 30% saved and 10% given, $4.20 is for spending. Saving $54.60 a year for 11 years gives $600.60.
Frequently asked questions
How much allowance should I give by age?+
A widely used rule is $0.50 to $1 per week for each year of age, so a 10-year-old would get $5–$10 a week. Increase it if the allowance must cover real expenses like lunches, clothes or a phone bill.
Should allowance be tied to chores?+
Families differ. Many pay a base allowance for learning money skills and treat everyday chores as expected, then pay extra for bigger optional jobs. What matters most is being consistent and explaining the rules up front.
What is the spend, save, give method?+
It splits every payday into three jars: money to spend now, money to save for a bigger goal, and money to give to a cause. Seeing the three amounts physically helps younger children understand budgeting.
Is weekly or monthly allowance better?+
Weekly works best for young children because the wait is short. Monthly suits teenagers who are learning to make money last and to plan for bills, much like an adult paycheck.
Why match my child’s savings?+
A match rewards delayed gratification the same way an employer 401(k) match does for adults. Even a 25%–50% match makes saving noticeably more attractive than spending.
