You can increase car finance payments, but the impact depends on the type of car finance agreement you have and how your lender chooses to apply the extra money:
To increase payments, you normally contact your lender and ask whether extra money will reduce the term or reduce future monthly payments.
Overpaying means paying more than your scheduled monthly repayment so the balance on your car finance agreement reduces sooner. An overpayment or a larger lump sum payment goes straight towards the outstanding capital rather than future instalments. As soon as the balance drops, the settlement figure falls.
Because interest is calculated on the remaining balance, overpayments also reduce the overall interest you pay
What changes next depends entirely on how the lender applies the extra money. Some shorten the loan term so the agreement finishes earlier. Others lower future monthly repayments instead, keeping the end date the same.
A family has a Hire Purchase agreement with a £240 monthly repayment and 24 months remaining. They choose to add £50 extra each month. Their lender treats this as an overpayment and applies the extra money directly to the outstanding balance. This reduces the settlement figure and cuts the interest almost immediately.
Because HP has no balloon payment, the lender adjusts the schedule and shortens the loan term by several months. The family finishes the agreement earlier and pays less overall. This outcome is typical of HP, but the exact reduction depends on the lender’s rules, which must always be checked in advance.
Increasing your payments does not directly improve your credit score, because credit scoring does not reward you for paying more than required. It rewards you for paying the agreed amount on time, every month, without arrears.
Extra payments do not give automatic credit-score benefits. Your lender reports your scheduled payments, not your voluntary overpayments.
However, overpaying can help indirectly. A lower settlement figure and a shorter loan term reduce the risk of missed payments later, which protects your score. Paying off the agreement early also does not automatically raise your score. Early repayment can even cause a short-term dip because the active credit account closes sooner.
There can be limits, and they differ by lender and agreement type. Some lenders cap large lump sum payments or apply fees once you exceed a certain threshold for example: one lender specifies that debit-card overpayments up to £10,000 are accepted, with larger sums subject to review. Many lenders also set minimum amounts for an overpayment so their system can process it correctly.
If your additional payments start pushing your agreement towards early settlement, certain charges may apply depending on your contract. PCP agreements may also place limits to protect the structure of the balloon payment.
Always check your agreement and get written confirmation from your lender before making significant overpayments.
