Speedrun Pace Calculator
Track split times and project finish time vs your PB or world record.
Quick Answer
Speedrun pace = current split sum + remaining PB splits. If you're 5 seconds ahead at the halfway mark, your projected PB is 5 seconds faster than current. Stay ahead through every split for a new PB. Sum of Best splits gives you the theoretical fastest possible time.

Enter PB time and current run time per segment. Leave current at 0 for unfinished splits.

About the Speedrun Pace Calculator
Speedrunning is the art of completing a video game as fast as possible, usually under specific category rules (Any%, 100%, glitchless, etc.). Pace tracking is core to the practice — without comparing your current run to past runs, you can't tell if you're on track for a PB until the very end.
How Splits Work
A speedrun is divided into segments called splits. Each split has a known PB time (your fastest completion of that segment in a successful run) and an all-time best time (gold split — fastest ever, regardless of run outcome). After completing a split, you compare current time to PB to know if you're ahead or behind pace.
The Tools Speedrunners Actually Use
LiveSplit is the dominant Windows tool for split tracking. It auto-loads splits via game-specific load detection, plays a sound on golden splits, and uploads to splits.io for community sharing. WSplit (older), Splitter (Mac), and BizHawk integrations exist for niche cases. This calculator does the math by hand for runners who want to plan a route without LiveSplit.
Sum of Best vs PB
Sum of Best is the time you'd get if you golded every split in one perfect run. It's a theoretical floor that's rarely achievable because the game state required for some golds is incompatible with the state needed for others. Top speedrunners get within 1-3% of Sum of Best for short games (under 30 minutes) and within 5-10% for long games (multi-hour).
Pace Strategy
Most runs end with a reset before completion. Runners reset when they fall significantly behind pace early — for example, dying in the first stage of a 30-minute run where reaching the end is unlikely to PB. Common reset thresholds: 10 seconds behind in a 5-min run, 30 seconds behind in a 15-min run, 90 seconds behind in an hour-long run.
Pair With Other Gaming Tools
Combine with our Elo Rating Calculator for ranked progression, the XP Required Calculator for grind projections, and the Gaming FPS Target Calculator if you're tuning your speedrun setup for low-latency play.
Verifying Your Run
For leaderboard submission on speedrun.com, you typically need: full unedited video of the run, splits visible on stream, and clear timing methodology (in-game time vs real-time). Some categories require frame-perfect timing analyzers. Always check the rules for your specific game and category before grinding.
