How to read this result
Three useful checks, kept deliberately short.
A RM300,000 loan at 4.2% for 20 years: Convert the annual rate to a monthly rate Β· Calculate the fixed monthly payment Β· Reduce the balance after each principal payment.
An optional extra payment reduces principal faster and can shorten the schedule.
Formula and assumptions
Monthly Payment = P Γ r Γ (1+r)^n Γ· ((1+r)^n β 1); each payment is split between interest and principalEarly payments contain more interest because the outstanding balance is larger.
Keep in mind: The schedule excludes lender-specific fees, rounding, changing rates and payment timing differences.
