A home loan calculator helps you move from "I can afford this property" to "a bank will actually finance it." In Karachi, most buyers need a mortgage to close the deal, so understanding your borrowing power before you search saves time and disappointment.
How home loans work in Pakistan
Banks in Pakistan offer financing for:
- Purchase of ready residential property
- Purchase of land or plots
- Construction and renovation
- Balance transfer from another bank
Most banks finance up to 70–85% of the property value for eligible applicants. You will need to cover the rest as down payment, plus registration and transfer costs.
Manual home loan calculation
You can estimate your monthly instalment with this formula:
Monthly Payment = [P × r × (1 + r)^n] ÷ [(1 + r)^n – 1]
Where:
- P = loan amount
- r = monthly interest rate (annual rate ÷ 12)
- n = total number of months
For example, a 50 lakh loan at 15% annual interest for 20 years gives a monthly payment of roughly PKR 65,900.
What banks check
- Monthly income and salary slip / business proof
- Age (usually 21–60 at maturity)
- Employment stability or business track record
- Credit history and existing loans
- Property value and legal status
- Down payment capacity
Down payment reality
If a bank finances 80% of a PKR 1 crore flat, you need PKR 20 lakh plus registration and legal costs upfront. Add agent commission, renovation, and moving costs before deciding your budget.
