Payment, schedule & payoff
Formula. Conventional loans use the standard amortization payment on the financed amount (price minus down payment); Islamic mode instead spreads a flat Murabaha markup and equal principal across the tenure. Extra payments shorten the schedule month by month.
payment = P × r × (1 + r)^n / ((1 + r)^n − 1), monthly rate r, n months
Assumes. fixed rate for the tenure (or two phases in dual-rate mode) · property tax and insurance are flat annual percentages added to the monthly total · typical PK pricing ≈ 1Y KIBOR + 3–4pp bank spread
Limits. Processing fees, valuation charges, life/property takaful pricing and floating-rate resets are not modelled — your bank's offer letter is the binding schedule.
