Concrete Steps Calculator
Calculate concrete volume for poured steps and landings. Includes rebar, form lumber, and cost estimates.
How to Use This Calculator
Concrete steps are a permanent feature that requires careful planning. This calculator helps you determine the concrete volume needed based on your step dimensions and landing requirements.
- Enter the stair width in inches (36 inches minimum for entry steps).
- Enter the number of steps needed based on your total rise.
- Specify rise height (typically 7-7.5 inches) and run depth (10-11 inches).
- Include landing dimensions if you have a platform at the top.
- Review concrete quantities and reinforcement recommendations.
Why This Matters
Concrete steps provide durable, low-maintenance access to your home. Unlike wood steps that require periodic maintenance and eventual replacement, properly constructed concrete steps can last 50+ years. Accurate concrete estimation prevents costly overages and ensures you complete the pour without running short.
- Calculate exact concrete volume for steps
- Include landing and base slab quantities
- Estimate rebar or wire mesh needs
- Plan form lumber requirements
- Budget for complete project costs
Worked Examples
Basic Entry Steps
A 36-inch wide entry with 3 steps (7.5" rise, 11" run) and 36-inch landing.
Wide Porch Steps
A 60-inch wide porch with 5 steps and 48-inch deep landing.
Basement Exit Steps
A 36-inch wide stairwell with 7 steps, no landing needed.
Common Mistakes to Avoid
- Not accounting for the solid mass under each step - steps are not hollow.
- Forgetting the base slab - steps need a foundation to prevent settling.
- Skipping reinforcement - unreinforced steps will crack and crumble.
- Rushing form removal - wait 24-48 hours minimum before removing.
- Not checking for level - uneven steps are both unsafe and code violations.
