Financial Calculators
Interactive tools for modeling Lantern's financial performance and planning at different scales.
Available Calculators
1. Fund Allocation Calculator
Model how revenue is allocated across Four Pillars, safe spaces, profit sharing, and operations at any scale.
Use for:
- Planning budget allocation at different revenue levels
- Understanding employee compensation at different company sizes
- Modeling safe space partnership funding
- Exploring sustainable growth vs. maximum profit-sharing scenarios
Inputs: Monthly revenue, employees, salary multiplier, profit sharing %
Outputs: Monthly budget by category, per-employee compensation, profitability metrics
2. Pilot Revenue Calculator
Project 12-month revenue, costs, and profitability based on merchant acquisition and churn.
Use for:
- Planning pilot phase financial projections
- Testing different acquisition and churn scenarios
- Finding break-even month
- Validating unit economics assumptions
Inputs: ARPU, infrastructure costs, merchant churn, new merchants per month
Outputs: Month-by-month cash flow, break-even timing, profit margin analysis
3. Unit Economics Calculator
Analyze profitability on a per-unit basis (per merchant, per user, per transaction).
Use for:
- Understanding customer acquisition efficiency
- Evaluating pricing strategy
- Identifying which segments are profitable
- Optimizing cost structure
Inputs: Revenue, merchants, users, transactions, COGS %, operating costs
Outputs: Per-unit revenue/cost/profit, gross/net margins, unit economics health
4. Salary Range Calculator
Design fair compensation scales with multiplier-based salary bands and verify compliance with 3× salary cap.
Use for:
- Planning salary structure for growing teams
- Ensuring salary fairness (max/min ratio compliance)
- Understanding payroll impact
- Visualizing compensation bands
Inputs: Base salary, role multipliers, team composition
Outputs: Salary bands, total payroll, salary ratio compliance, per-employee costs
How to Use These Calculators
- Select a scenario using the preset buttons
- Adjust inputs using either sliders or direct number entry
- View real-time results including tables, metrics, and insights
- Compare scenarios by changing values and observing impacts
All calculators are mobile-friendly and work in light/dark mode.
Choosing the Right Calculator
| Question | Calculator | Output |
|---|---|---|
| How should revenue be allocated at different scales? | Fund Allocation | Budget breakdown, compensation, profit sharing |
| Will the pilot be profitable in 12 months? | Pilot Revenue | Break-even timing, annual profit, margin analysis |
| How much profit do we make per customer? | Unit Economics | Revenue/cost/profit per merchant/user/transaction |
| Is our salary structure fair and sustainable? | Salary Range | Salary bands, payroll, compliance with 3× cap |

Technical Notes
All calculators use Vue 3 with real-time computation. No external dependencies or API calls — all calculations happen in your browser. Results are not saved; refresh to reset to defaults.
Accessibility: Calculators include number inputs alongside sliders for precise entry. Consider adding ARIA labels for screen readers.
