Compute Cost Reduction

monthly_savings = (cpython_hours - pyvorin_hours) * hourly_rate

With 3x speedup, you may be able to use smaller instance types or spot instances that would otherwise be too slow:

Instance	Before	After
c5.xlarge	Required	c5.large sufficient
Spot viable?	No (too slow)	Yes (meets SLO)

license_cost = 500  # monthly
compute_savings = 2000  # monthly
roi = (compute_savings - license_cost) / license_cost * 100  # 300%
