How to use
- Enter the capital that rabb-ul-maal invested.
- Enter the actual profit (write a minus number if there is a loss).
- Enter the agreed percent of the mudarib — both shares will be shown.
Good to know
- In mudarabah the investor (rabb-ul-maal) bears financial loss, while the manager (mudarib) loses their effort.
- The profit ratio must be agreed before the business starts — it cannot be a fixed guaranteed amount.
- Enter a loss as a minus number to see how the capital is affected.
- For real contracts, have the terms written down and reviewed by someone knowledgeable in Islamic finance.
Note: Under mudarabah rules, loss falls on the capital (the mudarib loses only their work), except when the loss is due to the mudarib's negligence or violation. The profit ratio should be fixed at the start; this tool is only a worksheet, not an agreement.
