Estimates for planning. Flat interest is charged on the full loan amount for the whole term; diminishing interest is charged on the remaining balance. The effective rate uses the amount the borrower actually receives after fees. Daily loans count 30 days a month (26 without Sundays). Lending in the Philippines is regulated by the SEC; disclose the full cost of credit to borrowers (Truth in Lending Act).
