Voluntary Termination Calculator: Work Out Your 50% Threshold

Voluntary Termination (VT) is a statutory right under Section 99 of the Consumer Credit Act 1974. It lets you hand a car back and end a regulated PCP or hire purchase agreement at any point before your final payment falls due.

The question most drivers actually want answered is simpler: have I paid enough to walk away owing nothing, or would I need to pay a shortfall first? That is what a Voluntary Termination calculator works out.

This page explains the maths behind that number and walks through a worked example. For the full process, letter template, and how VT affects your credit file, see our complete Voluntary Termination guide.

What a Voluntary Termination calculator works out

Under Section 100 of the Consumer Credit Act 1974, your liability on a Voluntary Termination is capped at one half of the total amount payable under the agreement, less whatever you have already paid or already owe.

In plain terms:

Amount you would owe to VT today = 50% of the total amount payable minus what you have already paid

If that figure comes out at zero or below, you can hand the car back today owing nothing further, subject to fair wear and tear and any arrears. If it comes out above zero, that is your VT shortfall: the amount you would need to pay on top of handing the car back.

A calculator just automates this sum against your own contract figures, rather than you working it out by hand each time you want to check.

What counts towards your 50% threshold

The 50% figure is based on the total amount payable, not just your monthly payments. It includes:

• Your deposit (cash or part exchange)
• Every monthly payment across the full term
• The balloon payment (Guaranteed Minimum Future Value) at the end

Because the balloon is included in that total, the halfway point in money usually falls later than the halfway point in time. On agreements with a small deposit, the 50% threshold often lands somewhere around 70 to 80% of the way through the contract, not at month 24 of a 48-month deal as many people assume.

The amount you have "already paid" for this calculation includes your deposit and every payment you have made so far, including any you paid up front.

Worked example

Here is a full worked example using round, representative figures.

Contract details:

Step 1: work out the total amount payable

Deposit + (monthly payment x term) + balloon £2,000 + (£320 x 48 = £15,360) + £8,140 = £25,500

Step 2: halve it

£25,500 / 2 = £12,750 (this is the 50% threshold)

Step 3: work out what has actually been paid

Deposit + (monthly payment x payments made) £2,000 + (£320 x 30 = £9,600) = £11,600

Step 4: compare the two

£12,750 threshold minus £11,600 paid = £1,150 shortfall

At payment 30, this driver would need to pay £1,150 alongside handing the car back to VT today. They have not yet reached the 50% threshold.

Step 5: work out when the threshold is reached naturally

£1,150 divided by the £320 monthly payment is just under 3.6, so it takes 4 more payments to clear it. By payment 34, total paid is £2,000 + (34 x £320 = £10,880) = £12,880, which is above the £12,750 threshold. From payment 34 onwards, this driver could VT with nothing further owed.

If you have not reached 50% yet

You can still exercise your VT right. The right to terminate under Section 99 applies at any point before your final payment, regardless of how much you have paid. You would simply need to pay the shortfall (Step 4 above) at the point you hand the car back.

Before deciding, it is worth comparing that shortfall against the alternative: settling the finance in full and selling the car yourself. See our guide to how PCP settlement figures are calculated if you want to work that out too. Whichever number is smaller is usually the cheaper route out.

If you are already past 50%

If what you have paid already equals or exceeds the 50% threshold, you can hand the car back with nothing further owed on the finance itself. Two things can still add to the bill:

• Damage beyond fair wear and tear. The finance company can charge for this under Section 100(4) of the Consumer Credit Act 1974.
• Arrears. Any missed payments that were already due before you terminate remain payable. Section 99(2) is explicit that terminating the agreement does not affect liability that had already built up before termination.

Excess mileage charges are a separately contested area. The strict wording of Section 100 caps your liability at 50%, but the Financial Ombudsman Service has accepted that a clearly disclosed excess mileage charge can still be fair on a PCP Voluntary Termination. Our full VT guide covers this in detail.

What a calculator cannot tell you

A Voluntary Termination calculator, this page's worked example included, gives you a planning estimate. It cannot replace a few things:

• Your exact figures. Your lender's own records of what you have paid and what your agreement states as the total amount payable are the definitive source. Ask them to confirm both if you are unsure.
• Vehicle condition. Whether the car meets the fair wear and tear standard is a judgement made at inspection, not something a calculator can predict.
• Arrears. If you are behind on payments, the exact arrears figure needs to come from your lender.

Always confirm your position in writing with your finance company before formally invoking VT.

FAQs

How do I calculate my Voluntary Termination amount?

Work out your total amount payable (deposit plus every monthly payment plus the balloon), halve it, then subtract what you have already paid (deposit plus payments made). If the result is zero or negative, you owe nothing further. If it is positive, that is your shortfall.

Is the 50% based on my monthly payments or the whole agreement?

The whole agreement. It includes your deposit and the balloon payment as well as your monthly payments, which is why the 50% point in money terms usually falls later than the halfway point in time.

Does a Voluntary Termination calculator include excess mileage?

Not in the core 50% calculation. Excess mileage is assessed separately at handback and can still apply if it was clearly disclosed in your agreement, even though the statutory cap itself is based purely on the amount paid.

Can I use a Voluntary Termination calculator before I have signed anything?

Not usefully. The calculation needs your actual deposit, monthly payment, term, and balloon figures from a real agreement, so it only works once you have a contract to calculate against.
