Useful next calculations
When to use this calculator
- When you need a fast estimate before making a bigger decision.
- When you want to compare a few scenarios using the same assumptions.
- When you need a clearer starting point before using a detailed quote or formal document.
- When you want to sanity-check a figure you have seen elsewhere.
A worked example
These are the example figures the calculator opens with.
| Input | Value |
|---|---|
| Provider settlement figure (£) | £12,000 |
| Current monthly payment (£) | £320 |
| Months left on current agreement | 36 |
For those figures the calculator returns:
- Settlement figure: £12,000.00
- Future current payments: £11,520.00
Method & assumptions
This planner separates three numbers that are often confused: the provider's current settlement figure, a realistic sale or trade-in value, and the future payments under a replacement quote. It makes any estimated negative-equity shortfall visible before a new monthly payment is compared.
The replacement route totals the entered monthly payments and separately payable fees only. It does not assume approval, sale proceeds, vehicle condition, insurance, maintenance, mileage charges, optional final payments or a particular early-exit right.
Get written figures and read the agreement before deciding. If payments are becoming difficult, contact the finance provider early and seek free independent debt advice rather than assuming refinancing is available or suitable.
Common mistakes
- Using optimistic assumptions without testing a more cautious scenario.
- Comparing outputs from different tools without checking that the inputs match.
- Treating the result as a final quote instead of a planning estimate.
- Rounding inputs too aggressively.
What to do next
- Try at least one more scenario so you can compare a realistic range.
- Use the related calculators below to cross-check the decision from another angle.
- Write down the key outputs from your best scenarios before you decide.
- If the result surprises you, change one input at a time to isolate the driver.
