Oxalate calculator

Add what you ate today, food by food or as whole dishes. The total uses the middle published value for each food, measured against 50 mg, the daily amount many kidney stone clinics aim for. Nothing you enter leaves this page.

Eating calcium with a high-oxalate food, like milk with cereal or cheese with spinach, binds some oxalate in the gut, so less reaches your urine. This calculator shows the oxalate eaten, not the amount absorbed. Not medical advice.
