About this calculator
Calculate click intervals and estimate total practice time. With a tempo ramp, total time divides the selected bars evenly among each step in the entered BPM schedule.
Worked example
calculated with the default values below
Tempo 96 BPM · Beats per bar 4 · Bars to practise 16 · Practice ramp step 4 BPM · Ramp steps 5 Click interval 625.00 ms · One bar lasts 2.50 seconds · Total time with ramp 37.0 seconds · Total beats 64 · Fastest tempo of the ramp 112 · Ramp schedule (BPM) 96 → 100 → 104 → 108 → 112

Disclaimer
These calculators give general estimates. Sizing, pricing, availability and standards vary by brand, retailer and country, so treat the output as a starting point and confirm it against the seller's or authority's own figures.
Implementation source
This record describes the implementation used by this page. It is not independent validation. External references, when available, support only the stated formula or definition; estimates and custom rules retain their own assumptions.
Formula and variables
T = Σᵢ ((bars × beats ÷ n) × 60 ÷ (BPM + i × ΔBPM))
- Δt
- beat interval, ms
- BPM
- beats per minute
- beats
- beats per bar
- bars
- bars to play
- T
- total time, ms
For a ramp, total beats are divided evenly among BPM steps; duration at each step is summed. The generated schedule cannot exceed 400 BPM.
Frequently asked questions
How does the tempo ramp affect practice time?
The selected total beats are divided evenly across the tempo steps, and the time at each step is added. The calculator rejects a schedule that exceeds 400 BPM; with a zero increment all steps remain at the starting tempo.
