Таамаг, тайлбар ба нийтлэг алдаа

Тооцооны таамаг

  • Payments occur monthly at the end of each period with a fixed payment amount.
  • APR is the monthly cash-flow discount rate multiplied by 12; jurisdiction-specific disclosure rules may differ.
  • Upfront fees reduce net proceeds; financed fees increase the repayment balance.

Үр дүнг хэрхэн тайлбарлах вэ

  • Interest rate excludes fees; APR includes the entered loan fees.
  • A payment below principal divided by term would require a negative rate and is not supported.
  • Rounded monthly payments can produce a slightly different implied rate.
