  • In the pack: 180 × 1 g = 180 g
  • £11.29 ÷ 180 g × 500 mg = 3.14p per 500 mg calcium
  • A week 3.14p × 7 = 22p · a month × 30 = 94p · a year × 365 = £11.45
  • Amount per serving: stated on the label.

Vitamin D3

  • Servings: 180 ÷ 1 per serving = 180
  • In the pack: 180 × 400 IU = 72,000 IU
  • £11.29 ÷ 72,000 IU × 1,000 IU = 15.7p per 1,000 IU
  • A week 15.7p × 7 = £1.10 · a month × 30 = £4.70 · a year × 365 = £57.23
