Compare Calculators

The fuel economy calculator works out how efficiently your vehicle uses fuel, reporting the result in both kilometres per litre (km/L) and litres per 100 km (L/100km) — the two measures used in Pakistan and internationally. Knowing your car's true economy is the first step to controlling fuel costs as petrol prices rise.

The calculation is a simple ratio: divide the distance driven by the fuel used. If you drive 300 km and refill 25 litres, your economy is 12 km/L. The reciprocal — 100 divided by km/L — gives litres per 100 km: in this case about 8.3 L/100km, the measure used in most international fuel consumption figures.

Why do the two measures matter? Pakistani buyers think in km/L (a Suzuki Alto at 15–18 km/L, a Corolla at 12–14), while international reviews and EU-style spec sheets use L/100km, where a lower number is better. This calculator shows both, so you can compare a local car against an imported spec sheet on equal terms.

Your real-world economy is almost always lower than the brochure figure. Traffic, air conditioning, carrying loads, tyre pressure and driving style can cut economy by 20–30% in city driving. To measure your actual figure: fill the tank completely, note the odometer, drive normally, then refill and divide the kilometres by the litres pumped. Average over several tanks for reliability.

Track the number over time — a sudden drop in fuel economy is often the first sign of a mechanical issue, such as under-inflated tyres, a clogged air filter or spark plug problems. Regular checks save both fuel and repair costs.

An EMI (Equated Monthly Instalment) is the fixed amount you pay a bank or lender every month until your loan is fully repaid. It is the single most important number to know before signing any home, car, bike, or personal loan agreement in Pakistan, because it determines how much of your monthly income goes to debt and for how long. This EMI calculator lets you see that figure instantly for any loan amount, interest rate and tenure.

The calculation follows the standard reducing-balance amortisation formula used by State Bank of Pakistan-regulated banks and non-bank finance companies. Interest is charged on the outstanding principal, not the original amount, which means early payments go mostly toward interest and later payments mostly toward principal. Understanding this is why comparing EMIs across banks can save you hundreds of thousands of rupees over a 10-year home loan.

When Pakistani banks quote a home finance rate, they usually offer KIBOR-based pricing — for example 'KIBOR + 3%'. The effective annual rate you enter should be the full percentage you will actually pay, not just the spread. Use your bank's stated effective rate, or the advertised rate for a car or personal loan, to get a realistic EMI figure rather than an optimistic one.

Use this calculator to experiment before you negotiate: increase the down payment to shrink the principal, lengthen the tenure to lower the monthly EMI (at the cost of more total interest), or shop between banks to find the lowest rate. A rule of thumb is that your total monthly debt payments should not exceed roughly 40–50% of your take-home income, so check your EMI against that before committing.

The results show your monthly EMI, the total amount you will repay (principal plus interest), and the total interest component. Keep these numbers when comparing bank offers — they reveal that a slightly higher rate over a long tenure costs far more than a small difference in the monthly figure suggests.
