One of the biggest mistakes in construction is not in execution but in incorrect pricing. Many professionals work hard and earn little because they do not know how to measure services correctly or calculate their real costs.
Before talking about price, you need to measure.
Practical example:
A wall 3 m high and 5 m long:
3 × 5 = 15 m²
Measurement errors lead directly to losses.
After measuring, calculate average consumption per square or cubic metre.
Simple example (masonry):
Always add 5% to 10% for waste.
Define your average productivity:
If you want to earn 300 (local currency) per day and you complete 10 m² per day:
300 ÷ 10 = 30 per m² (labour)
Include these in the final price.
After adding:
Apply a profit margin between 10% and 25%, depending on risk and complexity.
Applying 20% profit:
3,500 × 1.20 = 4,200
Those who do not measure correctly work in the dark. Estimating is not guesswork—it is calculation. Measuring, calculating real cost and applying the right margin turns an ordinary mason into a profitable professional.
