Scoring & Eligibility Models
Funds and banks that tie Qard al-Hasan loans to deposit history usually run this calculation in spreadsheets with manual formulas, and every time a rule changes, the work starts again from scratch. In Dara, the calculation is rule-based and open to review. Each night, the accounts' daily balances are read, the scoring policy assigned to each account records its daily and cumulative score, and the eligibility policy derives the financing limit from that score.

From balance to score
The scoring method determines how the balance is read. Some methods use the average daily balance, some the lowest end-of-day balance over the whole period, and others the lowest balance in each month, where the month can follow the Solar Hijri calendar. Under the daily score method, held amounts and dormant accounts can be given a lower weight. The tiered method splits the balance into bands, each with its own multiplier.
- Average daily balance
- Minimum end-of-day balance
- Monthly minimum by Solar Hijri month
- Separate weights for held amounts and dormant accounts
- Progressive tiers
From score to financing limit
The eligibility policy converts a score into an amount. Four models are available: a fixed multiplier, a tiered multiplier based on score ranges, a tenure bonus that raises the limit slightly for each month of membership, and a weighted combination of several methods. Once the amount is calculated, rounding and the minimum and maximum amounts are applied so the final figure is in line with the organization's bylaws.
- Fixed multiplier
- Tiered multiplier
- Tenure bonus
- Weighted combination
- Rounding, minimum and maximum amount
Rules outside the code
Each scoring method is a calculation template, and its parameters, such as the scoring unit, tiers and multipliers, are stored in the policy itself. Policies are versioned: if the board of directors changes a rule, a new version becomes active on a specified effective date, with no developer involved.
- Versioned policies with effective dates
- Parameter changes without a software release
