How we worked it out

Protein powder

  • Servings: 600 ÷ 30 per serving = 20
  • In the pack: 20 × 20 g = 400 g
  • £27.49 ÷ 400 g × 25 g = £1.72 per 25 g protein
  • A week £1.72 × 7 = £12.03 · a month × 30 = £51.54 · a year × 365 = £627.12
  • Amount per serving: stated on the label.

Caffeine

  • Servings: 600 ÷ 30 per serving = 20
  • In the pack: 20 × 64.8 mg = 1.3 g
  • £27.49 ÷ 1.3 g × 200 mg = £4.24 per 200 mg
  • A week £4.24 × 7 = £29.70 · a month × 30 = £127.27 · a year × 365 = £1548.43
