Perchain is a step-by-step money chain calculator for real-world purchases and selling workflows. Use it when a normal calculator is too flat: add sales tax, add card fees, add shipping, then convert the result from one currency to another. Or estimate a marketplace payout after fees and delivery costs. Each step stays visible, so the calculation is easier to inspect and reuse. Key features - Add percentage, fixed amount, and rate steps - Calculate each step from top to bottom - Use currency-pair rate steps such as USD to JPY - Start from templates for tax, card fees, overseas shopping, and marketplace scenarios - Add shipping costs quickly - Save repeated chains as templates - Save calculation history and export CSV - Supports Japanese and English How it works 1. Enter the starting amount and currency 2. Add tax, fee, shipping, discount, or exchange-rate steps 3. Review each intermediate amount and the final result Perchain does not provide live exchange rates or financial advice. It calculates from the values you enter and helps make multi-step money changes easier to understand.
