Step 1: Monthly interest amount
£1,000.00 × 5% = £50.00 per month
Step 2: Duration in months
6 months
Step 3: Total interest
£50.00 × 6 months = £300.00
Step 4: Total repayment
£1,000.00 + £300.00 = £1,300.00
APR = 100 × { (1 + C/P)1/t − 1 }
C = Total Interest • P = Loan Amount • t = Duration in Years
Step 1: C / P (Total Interest ÷ Loan Amount)
£300.00 ÷ £1,000.00 = 0.30000000
Step 2: 1 + C/P
1 + 0.30000000 = 1.30000000
Step 3: t (Duration in years)
6 months ÷ 12 = 0.50000000 years
Step 4: 1/t
1 ÷ 0.50000000 = 2.00000000
Step 5: (1 + C/P)1/t
1.300000002.00000000 = 1.69000000
Step 6: APR
100 × (1.69000000 − 1) = 69.00%
