1. How do you calculate how long it takes to save for something?

Answer: Divide the total cost by how much you can save each week. Example: a $60 goal with $5/week savings = 12 weeks.

2. How can cutting one want help you save faster?

Answer: If you normally spend $3/week on snacks and cut that, you can add $3 to your savings. That means $8/week instead of $5 — reaching your goal in about 8 weeks instead of 12.
