What is a mortgage calculator?
Mortgage Calculator - Commercial, Provident Fund, and Combined Loan Calculator is a free online tool for estimating home loan payments, total interest, and repayment schedules.
It helps users compare commercial loans, provident fund loans, and combined loans on one page before reviewing options with a lender.
How to use this mortgage calculator
Select the loan type, enter the loan amount, term, and interest rate, then choose the repayment method. The calculator displays the estimated monthly payment, total repayment, interest, and an early payment schedule.
You can switch between equal payment and equal principal to understand how the payment pattern changes over time.
Mortgage payment formula
For equal principal and interest payments, the monthly payment is usually calculated as P x r x (1 + r)^n / ((1 + r)^n - 1), where P is the loan amount, r is the monthly rate, and n is the number of monthly payments.
Equal principal payments divide the principal evenly across the term and calculate interest on the remaining balance each month.
Mortgage calculator example
For example, compare a 20-year provident fund loan with a commercial loan by entering the same principal and changing only the rate. The monthly payment and total interest will show how rate differences affect long-term cost.
For a complete housing budget, add property tax, insurance, maintenance, and local fees outside this estimate.
Frequently asked questions
Does this mortgage calculator include taxes and insurance?
No. It estimates principal and interest only. Add taxes, insurance, service fees, and local policy limits separately.
What is a combined loan?
A combined loan uses more than one funding source, such as a commercial mortgage and a provident fund loan. Each portion is calculated separately and then added together.
Which repayment method is better?
Equal payment is easier to budget because the payment is stable. Equal principal usually starts higher and then falls over time. The better choice depends on cash flow and lender rules.
