Curing Time For Meat Calculator

Work out curing time for meat instantly with clear inputs, formula shown and shareable results.

About Curing Time For Meat Calculator

Salt penetrates from all surfaces, so the controlling distance is half the thickest dimension. Penetration is roughly 2 mm per day for immersion at 4 C, slower for dry cure and much faster where brine is injected. Rate rises with temperature and with the square root of brine strength, and an equilibration period follows to even out the gradient.

Formula

Curing time

Days = (thickness / 2) / penetration rate, with rate adjusted for method, temperature and brine strength

Worked example

With the default values below, Curing Time For Meat Calculator returns Curing Time of 13.64. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
Under-curing cured meats risks botulism, which is often fatal. Follow a validated cure schedule and verify salt and nitrite penetration; do not rely on a calculated time alone.

Frequently Asked Questions

Why is temperature limited to a narrow range?

Below about 2 C penetration nearly stops and above 7 C spoilage organisms outpace the cure. Commercial curing rooms hold 2-4 C for this reason.

What happens if curing is cut short?

The centre remains under-cured, with insufficient salt and nitrite to inhibit Clostridium botulinum. This is the classic cause of botulism in home-cured hams.
