Debt Management Plan (DMP) Calculator UK 2025 — Monthly Payment & Debt-Free Date
A Debt Management Plan (DMP) lets you repay unsecured debts at a rate you can afford, with creditors typically freezing interest. They are informal arrangements — no court order — and free if set up through a charity. This calculator works out your DMP monthly payment, debt-free date, and how much interest you will save.
Always use a free DMP provider (StepChange, Citizens Advice, National Debtline). Never pay a fee for debt advice — fee-charging DMPs take money that should go to your creditors. A DMP is informal — creditors are not legally obliged to freeze interest, though most do. If your debts are unmanageable, also consider IVA, DRO, or bankruptcy.
How a Debt Management Plan Works
In a DMP, a debt adviser negotiates with all your unsecured creditors on your behalf. You make one monthly payment to the DMP provider, who distributes it proportionally among your creditors. Key features:
- Interest frozen — most creditors agree to stop charging interest, meaning all your payment goes towards reducing the balance
- One payment — you pay one amount per month; the provider handles distribution
- Informal — no court order, no insolvency register entry
- Flexible — if your circumstances change, payments can be adjusted
- Free — through charities (StepChange, Citizens Advice, National Debtline)

| Bankruptcy | Yes — typically 1 year | Yes | Severe — 6 years | Large debts, no assets, no prospect of repayment |
| DRO | Yes — after 12 months | No (registered) | Severe — 6 years | Under £30,000 debt, under £75/month disposable, under £2,000 assets |

Frequently Asked Questions
Creditors may still contact you in the early stages of a DMP. Once the DMP is established and creditors have accepted the reduced payment, most will stop calling. However, unlike an IVA, a DMP does not legally prevent creditors from taking action — they can still apply for a CCJ. In practice, creditors rarely take legal action against DMP customers who maintain payments, but it is possible.
DMPs only cover unsecured debts — credit cards, personal loans, overdrafts, store cards, catalogue debts. They cannot include: mortgage payments, secured loans, rent arrears, council tax arrears, court fines, child maintenance arrears, or student loans. These must be managed separately and should always be prioritised over unsecured debts.
If your DMP will take more than 6–7 years, an IVA might be worth exploring — it typically writes off remaining debt after 5–6 years, potentially making you debt-free sooner. However, IVAs have significant downsides: they appear on the Insolvency Register, certain professions are affected, and they are more restrictive. Take advice from a free debt adviser to compare all options.
