Midpoint Calculator: Fast, Simple, and Accurate

What It Does

This midpoint calculator finds the midpoint, distance and slope between two points.

Enter the coordinates then see the math and a clean plot.

The results show the formulas, the steps and the final values.

You get the midpoint as coordinates, the distance as a length and the slope value.

For a vertical line the slope reads undefined.

How It Works

These are the formulas used by the midpoint calculator.

• Midpoint formula: M equals ((x1 plus x2) divided by 2, (y1 plus y2) divided by 2).
• Distance formula: d equals the square root of (x2 minus x1) squared plus (y2 minus y1) squared.
• Slope formula: m equals (y2 minus y1) divided by (x2 minus x1).

Integers display as whole numbers without decimals.

Other values round to two decimals in the results.

The slope rounds to four decimals.

Point labels on the graph show one decimal.

Using the Calculator

Enter these four fields with numbers.

• x1: x value of Point 1.
• y1: y value of Point 1.
• x2: x value of Point 2.
• y2: y value of Point 2.

Use any number, decimals allowed.

After you click Calculate, you will see three outputs.

• Midpoint M: the center point between Point 1 and Point 2.
• Distance d: the straight line length between the points.
• Slope m: the rate of change, or undefined for a vertical line.

The tool plots Point 1, Point 2 and M on a grid.

A dashed segment joins the two points.

Benefits for Everyone

The midpoint calculator saves time for class, work and quick checks.

• Algebra and geometry practice with clear steps.
• Drafting or design sketches that need a center point.
• Map work that needs a halfway stop.
• Data plots that need length and slope.
• Quality checks for hand calculations.
