This guide presents the amount of damage reduction you get from every point of armour, and the formula for calculating it yourself.
Damage and vitality simply give +1% damage and max health respectively per point, while armour has a formula for how much damage reduction it gives.
It can be calculated as (ARMOUR x 100) / (100 + ARMOUR), so to find the damage reduction for 20 armour you would do (20 x 100) / (100 + 20), becoming 2000 / 120, resulting in 16.6% damage reduction.
