What is a debt management plan?
A debt management plan (DMP) is an informal agreement to repay your non-priority, unsecured debts through a single reduced monthly payment, arranged by a third-party provider who splits it between your creditors.
Instead of juggling several minimum payments you cannot meet, you make one affordable payment each month to a DMP provider, who distributes it to your creditors in proportion to what you owe each one. The provider asks creditors to accept the reduced payments and, ideally, to freeze interest and charges so the balance actually falls. A DMP repays everything you owe — it does not write any of it off — which is the key difference from formal insolvency solutions such as an IVA or a Debt Relief Order. For the full picture, including free versus paid providers and the credit-file impact, read our complete guide to what a DMP is.
How this calculator works
The calculator estimates your DMP payment as your monthly income minus your essential outgoings — the surplus a debt adviser would offer your creditors — then divides your total debt by that figure to give an indicative number of months to clear it.
A real debt adviser builds a detailed budget using the Standard Financial Statement, but the core idea is simple:
- Estimated monthly payment = your monthly income − your essential outgoings (never less than £1). This is the money genuinely spare after your essentials are covered.
- Indicative time to clear = your total unsecured debt ÷ your estimated monthly payment, rounded up to whole months. It assumes interest and charges are frozen.
- Total you would repay = your total debt, because a DMP repays your balances in full rather than writing any off.
- Per-creditor payment = your estimated payment ÷ the number of creditors, as a rough guide. A real plan splits it pro-rata by the size of each debt, not equally.
The important disclaimer
This is an illustrative estimate only. A real debt management plan is arranged and negotiated by a provider based on your full financial circumstances — this is not a debt management offer. Creditors are not obliged to accept a reduced payment or to freeze interest, so a real plan may cost more or take longer than the estimate here. The figures are meant to help you understand roughly how a DMP might look before you speak to a free adviser, not to replace that advice.
Debt management plan vs debt snowball or avalanche
A DMP is for people who cannot meet their minimum payments; the debt snowball and avalanche are for people who can. The deciding factor is whether your budget has a surplus after essentials and minimum payments.
If your income does not stretch to your essentials plus your contractual minimum payments, no repayment ordering can fix that — you need reduced payments negotiated on your behalf, which is what a DMP or a formal solution provides. But if you have a surplus and can keep up your minimums, a DMP would cost you the credit-file damage without the benefit. The debt snowball clears the smallest balance first for motivating quick wins, the debt avalanche clears the highest interest rate first to pay the least interest, and both keep every account in good standing.
| Feature | Debt Management Plan | Debt snowball / avalanche |
|---|---|---|
| Who runs it | A third-party provider | You manage it yourself |
| Best suited to | Budgets that cannot meet minimum payments | A budget surplus after minimums |
| Cost | Free via charities; commercial firms charge fees | Completely free |
| Credit-file impact | Severe — defaults and markers for 6 years | Positive — full, on-time repayment |
| Speed to debt-free | Slow — often 5+ years on reduced payments | Faster — strategic overpayments |
Not sure which side of the line you are on? The budget planner finds your real monthly surplus, and the snowball vs avalanche calculator shows how fast a positive surplus clears your debts. If the minimums alone are unaffordable, a DMP or a formal solution is the right next step — the IVA vs DRO vs bankruptcy guide compares the binding routes.
Is a debt management plan right for you?
A DMP fits when you have several unsecured debts, your minimum payments have become unaffordable, and you have a small, steady amount to offer creditors — but you do not need any of the debt written off.
Consider a DMP when several of these are true: you have more than one non-priority debt, your minimum payments are no longer affordable, you are not eligible for or do not need a debt write-off, and you want a single manageable payment with a provider dealing with creditors for you. It works best when your situation is a genuine but recoverable shortfall — enough income to pay something meaningful, just not the full contractual amount. If you owe more than you could ever realistically repay, a formal solution that can write off debt — an IVA, a DRO or bankruptcy — may fit better, so take free advice before deciding. Before any of this, check that you are dealing with your priority debts first, because a DMP only covers non-priority, unsecured debt.
