Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- One open straight run, no gates or shared corner/end posts. Spacing is supplied, not structurally designed.
Example Calculation
- Fence run: 30 m
- Maximum post spacing: 3 m
- Post unit price: 20
- Panel price per meter: 15
- Other fixed costs: 50
Fence run = 30 m; Maximum post spacing = 3 m; Post unit price = 20; Panel price per meter = 15; Other fixed costs = 50. Primary result: 720.
Frequently asked questions
How do I use this calculator?
Enter fence run, maximum post spacing, post unit price, panel price per meter, other fixed costs. The result updates automatically. Use Reset to restore the example values.
What method does it use?
posts=ceil(run/max spacing)+1; cost=posts ×price+run ×panel rate+fixed.. One open straight run, no gates or shared corner/end posts. Spacing is supplied, not structurally designed.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
