Web UI
Launch the interactive calculator: ./scripts/launch_ui.sh [port] # Default port: 5050 # Opens at: http://localhost:5050 # Auto-creates venv and installs Flask if needed Or manually: cd skills/financial-calculator python3 -m venv venv # First time only venv/bin/pip install flask # First time only venv/bin/python scripts/web_ui.py [port] Features: 7 calculator types with intuitive tabs Real-time calculations Interactive tables Beautiful gradient UI Mobile-responsive design
1. Future Value (FV)
Calculate what an investment will be worth in the future with compound interest. Use cases: Investment growth projections Savings account growth Retirement planning Inputs: Principal amount Annual interest rate (%) Time period (years) Compounding frequency (annual/quarterly/monthly/daily)
2. Present Value (PV)
Calculate the current value of a future amount (discounted value). Use cases: Loan valuation Bond pricing Investment analysis Inputs: Future value Annual discount rate (%) Time period (years) Compounding frequency
3. Discount Calculator
Calculate final price after applying percentage discount. Use cases: Retail pricing Sale calculations Cost savings analysis Inputs: Original price Discount percentage Outputs: Discount amount Final price Savings percentage
4. Markup Calculator
Calculate selling price from cost and markup percentage. Use cases: Product pricing Profit margin calculation Business pricing strategy Inputs: Cost price Markup percentage Outputs: Markup amount Selling price Profit margin (as % of selling price)
5. Compound Interest
Detailed breakdown of compound interest calculations. Use cases: Interest analysis Effective rate comparison Loan interest calculation Outputs: Final amount Total interest earned Effective annual rate
6. Future Value Table
Generate comparison table across multiple rates and time periods. Use cases: Investment scenario comparison Rate shopping Long-term planning Features: Add multiple interest rates Add multiple time periods View all combinations in sortable table See total gain and gain percentage
7. Discount Table
Compare multiple discount percentages for the same price. Use cases: Bulk pricing strategies Promotional planning Price comparison Features: Add multiple discount percentages See all discount scenarios Compare final prices and savings
Installation
Requires Python 3.7+ and Flask: pip install flask Or with venv: python3 -m venv venv source venv/bin/activate pip install flask
Python API
Import the calculation module: from calculate import ( future_value, present_value, discount_amount, markup_price, compound_interest, generate_fv_table, generate_discount_table ) # Calculate FV fv = future_value( present_value=10000, rate=0.05, # 5% as decimal periods=10, compound_frequency=12 # Monthly ) # Generate table table = generate_fv_table( principal=10000, rates=[0.03, 0.05, 0.07], # As decimals periods=[1, 5, 10, 20] )
Formulas
See references/formulas.md for detailed mathematical formulas, examples, and use cases for all calculations.
Tips
Rate Format: CLI: Use decimals (0.05 for 5%) Web UI: Use percentages (5 for 5%) Python API: Use decimals (0.05 for 5%) Compounding Frequencies: 1 = Annual 4 = Quarterly 12 = Monthly 365 = Daily Table Generation: Best practices for meaningful comparisons: FV tables: Use 3-5 rates, 4-6 time periods Discount tables: Use 5-10 discount percentages Keep tables focused for easier analysis Performance: Web UI calculations are instant Tables with >100 combinations may take a few seconds CLI is fastest for single calculations
Investment Planning
Use FV Calculator to project single investment Generate FV Table to compare different rates Check Compound Interest for detailed breakdown
Pricing Strategy
Use Markup Calculator to set selling price Generate Discount Table to plan promotions Compare margins and final prices
Loan Analysis
Use PV Calculator to value loan Check Compound Interest for total interest cost Generate FV Table to compare loan terms
