ReStory Repair Profit Calculator

Plan ReStory shop orders: enter repair/labor cost, parts price, and sale revenue to get profit, margin, and break-even sale price.

Enter the three numbers you observe in your shop: what the repair costs, what the parts cost, and what the customer pays. The calculator turns them into profit and margin planning numbers.

Shop fees, energy, or time-based costs of doing the repair.
Component / replacement part purchase price.
What the customer pays for the finished repair.

How to use

  1. Enter the repair/labor cost for the order (shop fees, energy, time).
  2. Enter the parts price for the device's components.
  3. Enter the sale revenue the customer pays.
  4. Read total cost, profit, margin, and break-even sale price.

Formula

Total cost = repair cost + parts price. Profit = sale revenue − total cost. Margin = profit ÷ sale revenue. Break-even sale = total cost.

P(at least one) = 1 - (1 - p)^n

Examples

Healthy order

Repair ¥1,200 + parts ¥800, sold at ¥4,200 → profit ¥2,200, margin ≈ 52.4%.

Loss-making order

Repair ¥3,000 + parts ¥2,500, sold at ¥4,000 → loss ¥1,500. Raise the price or skip the order.

Does this use live ReStory prices?

No. You enter the values you observe in your shop. Prices and fees vary by device and game version.

What counts as repair cost?

Anything the shop charges you to perform the repair — fees, energy, or time-based costs. The tool keeps repair and parts separate so you can compare them.
