Retaining Wall Calculator

Designing a retaining wall and need to verify it will not slide or overturn? Unsure if your footing width provides adequate safety factor? This calculator uses Rankine theory to compute active earth pressure, lateral forces, and stability checks so you can size walls with confidence. Enter wall height, base width, soil unit weight, friction angle, surcharge load, and concrete density. Get active pressure, resultant force, overturning moment, resisting moment, and safety factors for both sliding and overturning. WHAT IT CALCULATES: - Active earth pressure coefficient (Rankine) - Lateral force and point of application - Overturning moment and resisting moment - Safety factor against overturning - Safety factor against sliding - Required minimum base width KEY FEATURES: - Rankine active pressure theory - Surcharge load support - Sliding and overturning checks - Works completely offline - No account or login required Built for civil engineers, geotechnical engineers, and concrete contractors.
