Mortgage Calculator (Pakistan)

Mortgage in Pakistan: key elements

A mortgage (home finance) is a long-term financing facility secured against a property. You contribute equity (down payment), and the bank finances the remaining amount for a fixed tenure. You repay through monthly installments that include profit/markup (or rental in Islamic structures) plus any applicable taxes, takaful, and service costs.

What this calculator captures

• Property price, equity contribution, and resulting financing amount.
• KIBOR + bank spread pricing, with optional reset frequency and expected KIBOR change.
• Tenure, start date, and repayment schedule assumptions.
• Optional taxes and takaful, maintenance/service charges, and estimated upfront fees.
• Extra monthly payments, one-time prepayment, grace period, balloon payment, and settlement penalty.

Taxes, takaful, and fees (typical items)

• Property tax / CVT (provincial and property-type dependent).
• Takaful (home insurance) and mortgage protection, if required by the bank.
• Processing fee, legal + valuation, stamp duty / registration, and other upfront costs.
• Maintenance or service charges (if applicable to the project or society).

Regulatory and policy considerations (overview)

SBP sets broad frameworks for housing finance, but each bank applies its own eligibility rules and fee schedules. Common constraints include loan-to-value limits, debt-burden ratios, maximum tenure, valuation standards, documentation requirements, and takaful/insurance policies. These can vary by bank and change over time, so always confirm the latest terms before committing.

Documentation and process

• Typical documents: CNICs, income proof (salary slips or tax returns), and recent bank statements.
• Property documents: title deed/registry, ownership chain, approved map/plan, and sale agreement.
• Valuation and title verification are performed by the bank or its approved vendors.
• Disbursement timelines depend on document completeness, valuation clearance, and legal checks.

Risk and affordability

• Stress-test your affordability with a +2% rate scenario to gauge payment sensitivity.
• Inflation can affect both monthly affordability and resale value, so use conservative assumptions.
• A common guideline is to keep EMI within a safe percentage of monthly income, subject to the bank’s DBR rules.

What is behind this calculator

The results are produced from a simplified monthly schedule that models profit/markup using a standard amortization approach. For Islamic diminishing musharakah, the calculator uses a rental-based schedule that decreases as the outstanding balance reduces. These are industry-standard estimations and should be treated as planning figures rather than final bank offers.

Core calculation logic

• Monthly rate = (KIBOR + spread) / 12.
• Installment is computed using standard amortization for the selected tenure.
• Rate resets re-price the installment at the chosen interval using the expected KIBOR change.
• Grace period is modeled as interest-only during the specified months.
• Extra payments reduce the outstanding balance and can shorten the payoff date.
• Balloon payments and settlement penalties are added at the end when applicable.

How totals are assembled

• Total installments = total principal + total profit/markup + any extra or prepayments.
• Total out-of-pocket adds monthly taxes/takaful/maintenance plus upfront fees.
• Upfront fees are included in total costs but are not spread into monthly installments.

Output enhancements (recommended)

• Full amortization schedule (month-by-month principal, profit/markup, and balance).
• Split of principal vs profit/markup over time to visualize cost composition.
• Refinance break-even comparison (current facility vs revised rate + fees).
• Scenario comparison: Base vs Higher KIBOR vs Extra Payments.
