Objective

Calculate how much to save per month to hit a specific savings goal by a target date.

1

Tell the AI your goal (e.g., 'save $3,000 for a used car in 10 months').
2

Prompt: 'Calculate how much I need to save each month to hit this goal, and show 3 ways to split it weekly instead.'
3

Ask what happens to the monthly number if the timeline is extended by 3 months.
4

Ask the AI to suggest 2 realistic ways to find that extra monthly amount in a typical budget.
5

Build this as a simple reusable formula: (Goal - Current Savings) / Months Left.

Instructor TipShow the reusable formula on the board so students see the math behind the AI's answer, not just a black-box number.

TakeawayA savings goal only feels achievable once it's broken into a small, concrete monthly number.
