Estimate the dividend on cooperative shares held all year plus monthly share purchases weighted by months held, and the patronage refund on loan interest paid to the cooperative.
How it works
Many cooperatives pay dividends on a monthly weighted basis. Opening shares earn for 12 months; a purchase in month m earns for (13 − m) months if that month counts, or (12 − m) if counting starts the next month. Dividend = (opening shares × 12 + Σ new shares × months) × dividend rate ÷ 12. Refund = loan interest paid in the year × refund rate.
Example: THB 100,000 opening shares at 5% earn THB 5,000. Adding THB 1,000 every month gives 78 share-months when the purchase month counts: 1,000 × 78 × 5% ÷ 12 = THB 325, or 66 share-months and THB 275 if counting starts next month. THB 20,000 interest at a 10% refund returns THB 2,000.
Dividend and refund rates and month counting follow each cooperative's regulations and annual general meeting, announced after the accounts close. This is an estimate and excludes share withdrawals during the year or deductions for arrears.
Frequently asked questions
How do dividend and refund differ?
Dividends are based on shares held; refunds are based on business done with the cooperative, such as loan interest paid that year.
What if I did not buy shares every month?
Enter the consecutive months from the start of the year. If purchases stopped mid-year or varied, treat the result as an estimate or calculate each period separately and add them up.
Why might the result differ slightly from the actual payment?
The cooperative may round to whole shares, use cut-off days, or apply actual monthly balances with irregular purchases or withdrawals.
