What the numbers say

1. Months 1–2 are the tight spot. Cash drops to about $2,900 in month 2. Keep at least $3,000 in reserve or delay one hire until month 3.
2. Summer carries the year. Months 5–9 bring about two-thirds of annual profit, so plan marketing and staff holidays around them.
3. Price matters more than volume. Raising the average check by $0.50 lifts year 1 profit by about $16,900; selling 10% more cups adds about $15,000.
4. Payback. At the current pace, the $38,000 start-up spend is covered in roughly 13 months.
