Swimming Split Time Calculator

Work out swimming split time instantly with clear inputs, formula shown and shareable results.

About Swimming Split Time Calculator

Even-pace splits divide the target time by the number of split lengths in the race, and the per-100 figure normalises pace across race distances. Swimmers race by feel against a pace clock, so having the target split written down in seconds is what makes negative or even splitting executable.

Formulas

Split time

split = total time / (race distance / split length)

Pace per 100 m

pace = total time x 100 / race distance

Worked example

With the default values below, Swimming Split Time Calculator returns Time per split of 30.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Swimming Split Time figure worked out?

split = total time / (race distance / split length). Even-pace splits divide the target time by the number of split lengths in the race, and the per-100 figure normalises pace across race distances.

Why does this matter?

Swimmers race by feel against a pace clock, so having the target split written down in seconds is what makes negative or even splitting executable.

What do I need to enter?

Enter target total time, race distance, split length. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
