How to read this result
Three useful checks, kept deliberately short.
A RM100,000 loan at 4.5% a year over 10 years has 120 scheduled monthly payments: Monthly rate = 4.5% Γ· 12 Β· Scheduled payment β RM1,036.38 Β· Adding RM200 each month shortens the simulated payoff and reduces total interest.
This estimate excludes fees, insurance, taxes, variable rates, penalties and lender-specific allocation or rounding rules.
Formula and assumptions
Monthly Payment = P Γ [r(1 + r)^n] Γ· [(1 + r)^n β 1]At a fixed rate, each payment includes interest and principal. Early scheduled payments generally contain more interest; extra payments reduce principal sooner.
