Why Choose Yearly?
Your situation changes throughout the year:
- Stock price fluctuations
- Salary increases and promotions
- New grants and refreshers
- Quarterly RSU vests
Recalculate whenever you need:
- After each quarterly vest
- When stock moves +/- 20%
- After promotions or raises
- Before filing taxes in April
Most users recalculate 3-4 times per year. Monthly ($49) × 4 = $196. Yearly ($149) saves you $439.
