Finance terms
Annual Percentage Rate (APR) -- US and UK
The true yearly cost of borrowing, including interest and mandatory fees, expressed as a percentage. APR is higher than the headline interest rate when fees are involved. In the UK, lenders must quote a representative APR available to at least 51% of applicants. In the US, TILA requires APR disclosure on all consumer loans.
Balloon payment -- UK and US
A large final payment at the end of a PCP (UK) or balloon loan (US) that must be paid to own the car. In a PCP, the balloon equals the Guaranteed Minimum Future Value (GMFV) set at the start. You can pay it, hand the car back, or use any equity toward a new deal.
Capitalised cost -- US leasing
The agreed price of the car entering the lease. Negotiating this down reduces monthly lease payments. Cap cost reductions (deposits, trade-in equity) lower the amount financed.
CIBIL Score -- India
India's most widely used credit score, issued by TransUnion CIBIL. Ranges 300-900; 750+ is good. Banks and NBFCs use it to assess creditworthiness and set interest rates. Equivalent to FICO in the US or credit scores from Experian or Equifax in the UK.
EMI (Equated Monthly Instalment) -- India
The fixed monthly repayment on an Indian car loan. Each EMI has a principal component (growing over time) and an interest component (shrinking) under the reducing-balance method most Indian lenders use.
FICO Score -- US
The credit score most US auto lenders use (range 300-850). Scores above 720 get the best rates; scores below 620 are subprime, attracting higher interest or specialist lenders.
Flat rate vs reducing-balance rate
A flat rate charges interest on the original principal throughout the loan. A reducing-balance rate charges interest only on the outstanding principal -- the common method for Indian bank car loans. A flat rate of 7% is approximately equivalent to a reducing-balance rate of 13-14%.
GAP (Guaranteed Asset Protection) cover -- US and UK
If your car is written off or stolen, standard insurance pays market value -- which may be less than your outstanding loan balance. GAP cover pays the difference. Independently sourced GAP cover is usually cheaper than dealer-bundled GAP.
Hire Purchase (HP) -- UK
A credit agreement where you hire the vehicle from the lender while making monthly payments; ownership transfers with the final payment. Regulated by the Consumer Credit Act. Consumer has the right of voluntary termination after paying 50% of the total amount payable (Section 99 CCA).
Hypothecation -- India
A legal charge registered against a vehicle's RC, recording that a lender has a financial interest in the car. Must be formally terminated using Form 35 and NOC via the RTO after full loan repayment.
IDV (Insured Declared Value) -- India
The current market value of your car for insurance purposes, calculated by applying a depreciation schedule to the ex-showroom price based on vehicle age. The IDV is the maximum amount an insurer pays in a total loss claim. Compare IDVs across insurers -- some set them artificially low to offer lower premiums.
LTV (Loan-to-Value)
The loan amount as a percentage of the car's value. LTV of 80% on a Rs 10 lakh car means the loan is Rs 8 lakh; the buyer contributes Rs 2 lakh. Lower LTV typically earns a better interest rate.
Money factor -- US leasing
The finance charge on a car lease expressed as a small decimal (e.g. 0.00150). Multiply by 2,400 to approximate the equivalent APR: 0.00150 x 2,400 = 3.6%. Dealers may mark up the money factor above the lender's published buy rate.
NCB / NCD (No Claim Bonus / No Claims Discount) -- India and UK
A discount on the renewal insurance premium for each claim-free year. In India, NCB scales from 20% (1 year) to 50% (5 years) and is transferable between insurers. In the UK, No Claims Discount reaches up to 75% over 5-9 years.
NOC (No Objection Certificate) -- India
A certificate issued by a lender confirming the car loan is fully repaid and the lender has no further claim on the vehicle. Required for hypothecation removal, inter-state transfer, or sale. Typically valid for 90 days.
PCP (Personal Contract Purchase) -- UK
A consumer finance product where you pay a deposit, monthly instalments, and then choose to pay a balloon (GMFV) to own the car, return it, or use equity toward a new deal. Regulated by the Consumer Credit Act and FCA. Accounts for the majority of UK new car finance.
Residual value -- US and UK leasing
The predicted future value of a leased car at lease end, set by the lender as a percentage of list price. Higher residual = lower monthly payments. At lease end this is also the purchase-option price.
Insurance terms
Comprehensive insurance
The broadest motor insurance, covering own damage (collision, theft, fire) plus third-party liability. In India this includes mandatory third-party. In the UK it is called fully comprehensive. In the US it is split into collision and comprehensive.
IDV -- see Finance terms above
Third-party liability
Insurance covering damage or injury you cause to others. In India and the UK, third-party is the minimum legal requirement for driving on a public road. In the US, state minimum liability cover is required with varying limits.
Zero depreciation cover -- India
An insurance add-on that eliminates depreciation deductions on replaced parts during a claim. Standard policies deduct depreciation (e.g. 50% on rubber parts over 5 years); zero-dep pays full replacement cost. Recommended for cars up to 5 years old.
