Using the calculator is simple, even for beginners.

Step 1: Enter Debt Name

Start by entering the name of each debt.

Examples:

• Credit Card

This helps organise your repayment schedule clearly.

Step 2: Enter Current Balance

Add the outstanding balance for each debt.

Example:

• Credit Card Balance: £5,000

Make sure the amounts are accurate for better projections.

Step 3: Enter APR

APR stands for Annual Percentage Rate.

This represents the yearly interest charged on your debt.

Higher APR debts generally cost more over time.

Step 4: Add Minimum Monthly Payment

Enter the minimum monthly payment required for each debt.

The calculator uses these values to estimate repayment schedules.

Step 5: Add Extra Monthly Payment

If you plan to pay more than the minimum, enter an additional monthly payment amount.

Even small extra payments can reduce interest costs significantly.

Example:

• Extra Monthly Payment: £100

Step 6: Choose Repayment Strategy

Most advanced debt calculators allow users to choose between:

Debt Snowball Method

Pays off smaller balances first for motivational progress.

Formula Used in UK Debt Repayment Calculator

Debt repayment calculators use compound interest and amortization formulas.

Monthly Interest Formula

Monthly Interest = Current Balance × (APR ÷ 12)

Debt Payment Formula

Remaining Balance = Current Balance + Interest − Payment

Variable Explanations

Variable	Meaning
Current Balance	Outstanding debt amount
APR	Annual Percentage Rate
Monthly Interest	Interest charged monthly
Payment	Monthly repayment amount
Remaining Balance	Debt left after payment

Simple Explanation

The calculator calculates interest every month, applies your payment, and updates the remaining balance repeatedly until the debt reaches zero.

This process is repeated for all debts included in the repayment plan.

For snowball and avalanche strategies, the calculator also redistributes freed-up payments toward other debts as balances are cleared.

Example Calculation

Example 1: Credit Card Debt

Input Values

• Balance: £5,000
• APR: 24%
• Monthly Payment: £200

Calculation Process

Monthly Interest:

£5,000 × (24% ÷ 12)

= £100 monthly interest

First Month Principal Reduction:

£200 − £100 = £100

Remaining Balance:

£5,000 − £100 = £4,900

Final Output

• Estimated payoff time: Around 32 months
• Total interest paid: Approximately £1,300

Explanation

Increasing monthly payments would reduce the repayment period and lower interest costs.

---

Example 2: Personal Loan

Input Values

• Loan Balance: £12,000
• APR: 9.5%
• Monthly Payment: £250

Estimated Results

• Debt-free timeline: About 57 months
• Estimated interest paid: Around £2,200

Explanation

Because the APR is lower than a credit card, interest grows more slowly.

---

Example 3: Multiple Debts Using Avalanche Strategy

Input Values

Debt	Balance	APR	Minimum Payment
Credit Card	£5,000	24%	£120
Personal Loan	£12,000	9.5%	£220
Store Card	£1,300	29.9%	£45

Extra Monthly Payment: £100

Final Results

• Total payoff time: Reduced significantly
• Interest savings: Higher than snowball method
• Debt-free date: Earlier than minimum payments only

Explanation

The avalanche strategy prioritises high-interest debts first, helping users save money long term.
