Girvi interest schemes the software supports

Monthly

Most common

• Interest = amount × rate % per month × months
• Girvi date and release date are both counted
• Choose how a part month is charged: full, completed only, day-wise or 15-day slab

15 days slab

Half / full month

• After full months, 15 days or less = ½ month
• More than 15 days = 1 full month
• Popular with pawn brokers for fair, simple billing

One month compulsory

Minimum interest

• At least 1 month interest even if released early
• Then monthly, 15-day slab or daily after the first month
• Minimum can also be days or a fixed amount

Daily

Day-wise

• Per-day rate = monthly rate ÷ 30
• Charged for the exact number of days
• Good for short-term loans

Weekly, quarterly & yearly

Other periods

• Weekly = rate ÷ 4, quarterly = rate × 3, yearly = rate × 12
• Yearly-always and one-month-then-weekly schemes built in

Compound after 11 / 12 months

Unpaid interest added

• Unpaid interest is added to the principal after N months
• Can repeat every N periods, with an optional limit
• Count from the bill date, expiry, due date or last paid date
• Paid interest is never compounded

Your own scheme

Fully custom

• Duplicate any built-in scheme and change the rules
• Rounding: none, nearest, up or down
• The scheme is frozen on each bill — later changes affect only new bills

Part payment & top-up rules

Store-wide

• When a top-up starts earning interest
• When a part payment reduces the principal (current or next cycle)
• Whether old interest must be cleared first
