When do I get the thing?
Put in what it costs, what is already saved, and what goes in each week. The date is the answer a child actually wants. Then try the last box: the one small thing skipped each week, and how many weeks sooner that makes it.
Time to the goal
20 weeks
Around February 2, 2027, saving $5 a week.
Rounded up to whole weeks. Change one number and watch the date move; that is the conversation to have with a child.
What this teaches
A goal with a date is a plan; a goal without one is a wish. The trade-off box makes opportunity cost visible without using the words.
