FAQ
Is DebtRiot really private?
Yes. Calculations run locally in your browser and we don’t receive the figures you type into the calculator. We only run basic, anonymised analytics if you consent in the cookie banner.
What do I need to use the calculator?
You can either enter your full monthly budget (take-home pay, essentials and an emergency buffer) or enter a single monthly “budget for debts” if you already know what you can afford. For each debt, use your latest lender statement/app for balance, rate type (APR/EAR) and minimum payment.
Does it support overdrafts and 0% deals?
Yes. Select APR or EAR for each debt (overdrafts often use EAR). If a 0% deal ends after a set number of months, enter the promo details so the model can switch to the standard rate.
Does DebtRiot handle UK overdrafts correctly?
Yes. Unlike most calculators built for the US market, DebtRiot understands the difference between APR (used for credit cards and loans) and EAR (used for UK overdrafts). Just select the rate type and we calculate the interest correctly.
What are snowflakes?
Snowflakes are one-off extra payments you can make when you have spare cash — like a bonus, tax refund or gift money. Choose the month you expect it and the plan will show the impact on your timeline.
How much does DebtRiot cost?
Comparing strategies and previewing your plan is free. Downloading the full personalised PDF plan is a one-time payment (£9.99) — no subscription. After purchase, you can generate updated plans using your Recovery Code (fair-use and device limits apply).
Is this regulated financial advice?
No. DebtRiot is an information and planning tool — not regulated debt advice. If you need personalised help, free and confidential support is available from StepChange or National Debtline.
