Determine the number of bags of portland cement required for a given volume of mortar based on the cement-to-mortar ratio.
Enter your values below
Total volume of mortar needed.
Proportion of cement in the mix (e.g. 1 in a 1:3 mix).
How this calculator works
The mortar volume is multiplied by the cement ratio to get the cement volume, then divided by the volume of one 94 lb bag of portland cement (≈ 0.0347 cu ft) to yield the number of bags.
