Profit estimator
Launch margin estimate
Estimate whether one product cycle covers its cost. Every number is typed by you. The public listing does not publish part prices, sale prices, or a marketing percent.
Gross value = sell value × cycles × quantity × (1 + bonus ÷ 100). Net profit = gross value − unit cost × quantity.
Sample defaults are round demonstration numbers, not prices from Build a Phone Empire. seedCost is your unit cost, sellValue is the price you set, harvests is how many sales you expect in the cycle, quantity is how many units that cycle covers, and valueBonusPercent is any extra you already know about, such as a pass whose name you trust. Leave the bonus at 0 when you do not know one.
Upgrade payback
Upgrade payback estimate
Estimate how many cycles an in-game cash upgrade needs to earn back its cost. Use numbers from your own session. This does not price Robux passes or claim a hidden payback formula.
Payback cycles = upgrade cost ÷ extra profit per cycle, rounded up.
Sample defaults are not game data. Enter the cash cost you see, the extra profit you expect each cycle after the upgrade, and how many minutes one cycle takes in your session.
