Maintenance capex ratio calculator

Estimate what share of total capital expenditures is represented by maintenance capital expenditures.

Result

39.6%

Estimated maintenance capex ratio based on maintenance capital expenditures divided by total capital expenditures.

Maintenance capex ratio39.6%

Maintenance capex used$95,000,000

Total capex used$240,000,000

Estimated growth capex$145,000,000

$95,000,000 of maintenance capex out of $240,000,000 of total capex gives a maintenance-capex ratio near 39.6%.
That leaves about $145,000,000 of capex classified outside the maintenance portion in this simple split.
Use the result as a rough allocation check only, because maintenance-versus-growth capex definitions can vary a lot between companies and analysts.

This is a simple capital-allocation ratio, not financial advice. Companies can define maintenance and growth capex differently, so use the result as a rough comparison metric only.
