- Currency earned per hour = 5000
- Item price = 250 000
- Current balance = 30 000
- Currency spent per hour on upkeep = 800
- Session length = 1.5
- Net income per hour = 5000 - 800 = 4200
- Currency still needed = max(250 000 - 30 000, 0) = 220 000
- Hours to afford it = 4200 > 0 ? 220 000 / 4200 : 0 = 52.381
- Sessions needed = 1.5 > 0 && 52.381 > 0 ? 52.381 / 1.5 : 0 = 34.9206
- days_at_one_session = 34.9206 = 34.9206
- Time to afford it = 52.381 * 3600 = 188 571
- Price as hours of net income = 4200 > 0 ? 250 000 / 4200 : 0 = 59.5238
- Share of income lost to upkeep = 5000 > 0 ? 800/5000*100 : 0 = 16
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- hours = (price - balance) / (income - sink)
A negative net income means the upkeep exceeds the earnings and the goal is unreachable at this rate.
