Plot division calculator

How it works

Usable area = total area × (1 − roads and open space %). Equal parts: usable area ÷ number of parts. Plots of a size: whole plots = usable area ÷ plot size, rounded down, and the rest is left over. The road share is your own figure, so follow your approved layout.

How to use it

1. Type the plot area and choose its unit.
2. Type the share kept for roads and open space, or 0 if none.
3. Choose equal parts or plots of a size, and read the result.

Worked example

1 acre is 43,560 sq ft. With no road space and plots of 200 gajam (1,800 sq ft), 43,560 ÷ 1,800 = 24.2, so you get 24 plots and 360 sq ft (40 gajam) is left. Split into 4 equal parts instead, each is 10,890 sq ft, or 25 cents.

Common mistakes

• Entering 0 for roads when the layout needs them. Use the share in your approved plan.
• Forgetting that plots are not always the same shape. Frontage and depth also matter, not only area.
• Ignoring the leftover. It may be too small to sell as a plot.
