    Method Notes

    All volumes are computed in mL internally. For fl oz inputs, conversion uses 1 fl oz = 29.5735 mL.

    Daily usage accounts for waste percentage by dividing by (1 − waste%). Totals are rounded conservatively where appropriate for planning.

    FAQs

    Typical soap dispensers output 0.8–2.0 mL per press. If you do not know the exact yield, start with 1.5 mL and use the tolerance slider to understand best‑ and worst‑case scenarios.
    Many hygiene protocols recommend enough soap to fully cover hands for at least 20 seconds of scrubbing. Two to four pumps is common depending on yield and viscosity. Adjust until coverage is reliable.
    Thicker soap can reduce the delivered volume per press. The factor scales yield directly. Values below 1.00 assume reduced flow; values above 1.00 assume slightly higher delivery for thin products.
    Waste covers drips, misfires, and over‑dispensing. The calculator increases required volume by dividing by one minus the waste rate so your plan includes an operational margin.
    Yes. Change the pump yield using presets or enter custom values. Recalculate to see how pumps per bottle, washes per bottle, and cost per wash vary between devices.
    Foam and gel systems have different yields. Measure a few presses into a graduated cup to find the actual volume, then plug that into the calculator. Adjust viscosity factor if needed.
    Accuracy depends on the quality of your inputs. The tolerance control provides bounds. For critical environments, verify yields periodically and monitor actual consumption against the plan.
    Enter the unit price per bottle. The tool computes cost per mL, per wash, per day, and projected spend for the coverage period. Leave at zero to skip cost analytics.
