Overview
Formuley includes 13 connected calculators across bench work, scaling, release prep, and production planning. Some tools are open to all users, while chemist-grade workflows unlock on Maker and Pro.
You can open calculators from the main calculator lab, directly from a formula, or from a batch when the workflow depends on production data.

- Preservative Calculator: screening math plus advanced builder guidance.
- Active Matter Calculator: surfactant active matter balancing.
- Fragrance Load Calculator: IFRA-style screening for quick checks, with certificate mode on Pro.
- Solubilizer Ratio Calculator: starting ladders for clear fragrance and oil-soluble systems.
- Neutralization & Thickener Calculator: polymer and neutralizer planning for gels, lotions, and serum systems.
Adjust & Scale
- Concentration & Assay Calculator: dilution, stock correction, and carried solvent math.
- pH Adjustment Calculator: acid or base estimation for a target pH.
- Density & Fill Calculator: declaration unit, overfill, and packout planning.
- Overage & Yield Calculator: process loss, overage, and saleable output planning.
- Unit Conversion Calculator: percent, weight, and volume conversion with density support.
Specialty
- SPF Contribution Calculator: theoretical UV-filter contribution planning.
Formula and Batch Context
- Formula-aware calculators prefill values like batch size, water phase, fragrance load, or thickener hints from the formula record.
- Batch-aware calculators currently apply to Density & Fill and Overage & Yield, where packout and actual-yield snapshots matter.
- The legacy Dilution Calculator route now redirects to Concentration & Assay.
Important Limits
- Preservative guidance is still planning support. Challenge testing is required before release.
- Solubilizer and neutralization outputs are bench starting points, not final release decisions.
- SPF output is theoretical only and does not replace accredited testing.
- IFRA screening is directional. For release work, use the certificate-driven IFRA mode with the exact supplier certificate and amendment.
