24-Hour Urine Creatinine Clearance Calculator
CrCl = (U_cr · V_urine) / (P_cr · 1440) — measured (not estimated).
Compute creatinine clearance directly from a 24-hour urine collection: CrCl = (urine creatinine × 24-h urine volume) / (serum creatinine × 1440 min). Reports CrCl in mL/min — a true measured value rather than the Cockcroft-Gault estimate.
How to use this calculator
- Fill in the inputs above using the units you already have.
- Values update automatically as you type — no submit button needed.
- Hover any result row for the underlying formula and intermediate values.
