Where flat beats metered — the break-even crossover
Break-even, in one chart
Where flat beats metered#
Metered billing climbs with every task; a flat plan holds its price. Scroll through the four steps to watch the two lines cross — first on monthly billing, then on annual.
- Metered · $0.80/task
- Allegretto monthly · $39
- Allegretto annual · ≈$31/mo eff.
| Tasks/mo | Metered @ $0.80 | Allegretto $39 | Lower |
|---|---|---|---|
| 24 | $19.20 | $39 | Metered |
| 49 | $39.20 | $39 | ≈ Tie |
| 120 | $96 | $39 | Flat (−$57) |
Step 1 · Metered climbs
Every task adds about $0.80.
At the $0.80/task reference, 120 tasks run ≈$96/mo — the rising line. Double the tasks, double the bill.
Step 2 · Flat holds at $39
Allegretto costs $39 at 10 tasks or 150.
The lines cross at ≈49 tasks/mo ($39 ÷ $0.80). Below it, metered billing or a free route costs less — flat only wins past the crossing.
Step 3 · Annual lowers the crossing
≈$31/mo effective moves it to ≈39 tasks.
Annual billing is ≈$372 upfront vs $468 across a year — ≈$96 less. Worth it only if volume holds all year; the refund terms decide.
Step 4 · Your turn
Place yourself on the line.
At 120 tasks/mo: metered ≈$96/mo vs $39 flat — flat costs less by ≈$57.
