Useful tools for home preserving
These calculators help you work through proportions faster, avoid common mistakes and use recipes with more confidence. They are practical tools for people who want to move from reading to doing.
Choose the calculator you need
Each tool solves a specific kitchen task: scaling marinade, salt and sugar ratios, estimating pectin for jam, or converting vinegar strength.
Marinade calculator
Quickly calculate water, salt, sugar and vinegar for the number and size of jars you need.
Salt and sugar
A practical tool for fast ratio calculations across different liquid volumes and preserving batches.
Vinegar converter
Convert between common vinegar strengths for home preserving recipes.
Pectin calculator
Estimate pectin, sugar and acidity for jam and fruit preserves.
Brine calculator
Get the correct amount of salt and water for fermentation and brining.
Drying yield
See how much dried fruit, mushrooms or herbs you can expect from fresh produce.

Shelf life
Estimate storage periods for jams, marinades, fermented foods and dried produce.
What is useful to open next
Calculators work best together with recipes, practical explainers and ingredient-based browsing.
Start with the total batch volume or product weight, then convert the ratios. That is the easiest way to avoid small but costly mistakes.
