## Calculators

### Salon & Spa Tip Calculator
- URL: https://lldtek.com/tools/salon-tip-calculator
- Answers: What to tip on a service, and how to split it across everyone who worked on you.
- Math: service total × tip rate, then ÷ number of people who worked on the service.
- Also shows the tip amount at 15/18/20/25% for quick reference.
- Inputs stay on the device.

### Service Pricing & Margin Calculator
- URL: https://lldtek.com/tools/service-pricing-calculator
- Answers: The price that hits your target margin, and the margin you're actually running at your current price.
- Math: (product cost + labor cost) × (1 + overhead rate), then solved for price at the target margin.
- Context: cost-plus pricing, the method the SBA and SCORE recommend for labor-heavy service businesses.
- Inputs stay on the device.

## Generators
