Quick answer
Common whole-muscle equilibrium starting points: 2–3% salt (2.5% is typical), 0–1% sugar, and 0.25% Cure #1 — about 156 ppm ingoing nitrite with a 6.25% product. For a dry EQ cure every percentage is taken against meat weight; include water in the basis only when your recipe is an equilibrium-brine formulation. Enter your targets below and the calculator returns the gram amounts.
Equilibrium Curing Calculator
Calculates curing salt, plain salt and sugar from percentage targets on your chosen basis — dry cure by default, or meat + water for an equilibrium brine. Results update as you type.

Assumptions, units and limits
- Ingredient mass = calculation basis × target %. The basis is meat weight for a dry cure, or meat + added water when brine mode is on. Those two models answer different questions — never mix conventions between them.
- The tool assumes the non-nitrite portion of your cure blend is salt and deducts it from the plain-salt amount. For 6.25% products that is 93.75% salt — a standard modeling assumption, not a guarantee for every proprietary blend.
- Common starting points, not rules: salt 2–3%, sugar 0–1%, cure 0.25% of meat weight (≈156 ppm ingoing nitrite for a 6.25% product). Your tested recipe is the controlling source.
- Cure time is not calculated here. As a planning heuristic only, whole-muscle equilibrium dry cures are often allowed about one day per 6 mm (¼ in) of thickness plus a small buffer — but the validated recipe or process you follow decides the real schedule.
- This is formulation math only: it does not validate temperature control, sanitation, fermentation, drying or shelf stability.

What is equilibrium curing?
In an equilibrium-style formulation, ingredients are calculated from a target percentage rather than applying a large excess and later estimating how much salt the meat absorbed. The goal is to make the recipe math repeatable on the chosen basis.
For example, a 2.5% salt target on a 1,000 g basis corresponds to 25 g of total salt in the model. The calculator then separates curing-salt contribution from additional salt according to the entered cure composition assumptions.
1,500 g belly at 2.5% salt, 1% sugar, 156 ppm
Cure #1 (6.25%): (156 × 1,500) ÷ 62,500 = 3.74 g. Total salt: 1,500 × 2.5% = 37.5 g, of which 3.51 g already rides in the cure blend (93.75% salt), leaving 34.0 g of plain salt to add. Sugar: 1,500 × 1% = 15.0 g. Total mix: about 52.7 g.
Dry cure vs equilibrium brine
The calculator distinguishes between a meat-only equilibrium model and a meat-plus-water brine model. That distinction matters because adding water changes the calculation system and therefore the amount produced by a percentage-based formula.
| Method | Calculation basis | What to watch |
|---|---|---|
| Equilibrium dry cure | Meat mass | Use the actual meat weight and ingredient targets. |
| Equilibrium brine | Meat + added water | Be explicit about whether the selected formulation was designed on this basis. |
| Retained pump | Green meat + retained pickup in the calculator model | Commercial regulatory calculations can use a different basis; verify the applicable standard. |
Why an equilibrium formula is not automatically foolproof
Equilibrium calculations reduce one source of variability, but they do not remove measurement error or process risk. Meat thickness, temperature, sanitation, water activity, pH, time and cooking or drying procedures can all affect the outcome.
Cure time is a process question, not a formulation output
This page’s calculator returns weights, not a curing schedule. For whole-muscle dry equilibrium cures, curers commonly plan around roughly one day per 6 mm (1/4 inch) of thickness at the thickest point plus a small buffer — but temperature, density, bone and the recipe all shift the real time, and the tested recipe or process you follow decides the actual schedule and endpoint.
Common mistakes
- Using a recipe percentage designed for meat-only calculations in a meat-plus-water system.
- Assuming the non-nitrite fraction of every proprietary cure blend is plain salt.
- Skipping label verification.
- Assuming equilibrium math alone creates a shelf-stable or pathogen-controlled product.
Frequently asked questions
What salt percentage should I use for equilibrium curing?
Common whole-muscle starting points fall between 2% and 3% salt by weight, with 2.5% a typical choice, and sugar anywhere from 0% to about 1%. These are conventions, not safety limits: the tested recipe you follow should set the targets, and this calculator turns those targets into weights.
How much cure do I add in equilibrium curing?
The common convention is 0.25% of meat weight for a 6.25% nitrite product — about 156 ppm ingoing nitrite. If you prefer to work from a ppm target directly, the calculator converts the target into a cure weight; both modes produce the same batch when the numbers match.
How long does an equilibrium cure take?
A widely used planning heuristic for whole-muscle dry equilibrium cures is about one day per 6 mm (1/4 inch) of thickness at the thickest point, plus a small buffer. It is a planning aid, not a validated schedule: temperature, density, bone and the recipe all affect the real time, and the process you follow decides the endpoint.
Should I include the water in brine calculations?
Only if your formulation was designed on a meat-plus-water basis. In an equilibrium brine, the water is part of the calculation system, so percentages are computed against meat + water. Using a meat-only percentage in a brine system under-salts the batch; using a brine percentage on meat alone over-salts it. Pick the basis your recipe uses and keep it consistent.
