Monthly instalment
The monthly instalment is estimated with reducing-balance math. This is more realistic than dividing the principal by the number of months.
Total interest
A longer term can lower the monthly payment but increase total interest. Showing interest separately helps users compare loan offers.
Admin fee
Fees can make a loan more expensive even if the monthly instalment looks manageable. The calculator adds a simple fee field for planning.
Extra payments
Paying extra each month reduces the balance faster. The calculator simulates this to estimate a shorter payoff period.
Affordability check
Debt-to-income is not a bank approval decision, but it is a useful early warning signal before applying.
Common questions
