About the Home Loan Calculator
A housing loan starts with a subtraction rather than a formula: the amount borrowed is the property price less whatever you pay upfront. That figure then runs through the reducing balance instalment formula over the number of months in the tenure. Because a mortgage is large and long, a rate difference of a quarter point moves the lifetime interest by a serious sum, which the total interest line makes obvious.
The monthly outgo shown here adds property tax and insurance to the principal and interest, since those are usually collected with the payment and decide what the household actually pays. Loan to value is reported too, as lenders price in bands: pushing the deposit high enough to cross under eighty percent often unlocks a better rate and removes mortgage insurance in markets that charge it.
The early years section shows the first month split and the approximate interest paid across the first twelve payments. On a thirty year loan that first year is dominated by interest, which is why overpaying at the start repays far more than the same amount later. Do budget for costs this page cannot know: stamp duty or registration charges, legal fees, valuation fees and moving costs. If you want the plain instalment without the property framing, the EMI Calculator is the simpler page.
How to use
- Enter the agreed property price and the deposit you can pay upfront.
- Set the interest rate and the tenure in years the lender has offered.
- Add a monthly figure for property tax and insurance if they are collected with the payment.
- Compare the loan to value line against the lender bands to see if a bigger deposit earns a better rate.
Common questions
- How much deposit do I need?
- Most lenders want at least ten to twenty percent of the price. Crossing the twenty percent mark usually improves the rate and avoids mortgage insurance.
- What is loan to value?
- The loan divided by the property price, as a percentage. Lower is safer for the lender, so it is priced more cheaply.
- Does the payment include maintenance?
- No. Service charges, repairs and utilities sit outside the loan and should be budgeted separately from the monthly figure here.
- How much does a shorter tenure save?
- A great deal. Cutting a thirty year term to twenty raises the payment moderately but removes roughly a third of the lifetime interest at typical rates.
