💰 Interest & Loan

Compound interest assumes monthly compounding with contributions added each month. Loans use standard amortization; with a two-phase rate, the equal payment is recomputed on the remaining balance when the teaser ends, the way banks reset it when a floating rate changes. The floating rate here is one figure for the whole remainder; real banks revise it every 3 or 6 months. Interest is computed with equal months (annual rate ÷ 12), while Vietnamese banks accrue on actual days over a 365-day year (Circular 14/2017/TT-NHNN), so each period on your statement differs slightly. The schedule rounds payment and interest per period and books the rounding remainder into the last period, so principal sums to the loan exactly. Numbers are unit-free — read them as VND, USD, anything.
