How This Calculator Works
- Combines employee monthly contribution with employer match.
- Applies monthly compounding using annual growth + dividend yield.
- Estimates tax savings from employee contribution amount and tax rate input.
- Provides a planning estimate, not tax or investment advice.
Share Incentive Plan Formula
This calculator uses future value of a monthly contribution stream with compounding.
- P = total monthly contribution (employee + employer match)
- r = monthly rate ((growth + dividend) / 12)
- n = total number of months
Example SIP Projection
If you invest $250/month for 5 years, get 20% employer match, and expect 8% total annual return (growth + dividends), your SIP value can be materially higher than investing without match.
Employee only
Lower future value
With employer match

Key Assumptions
- Returns are modeled as smooth monthly compounding and not actual market volatility.
- Employer match is assumed to apply consistently each month.
- Tax savings are estimated from your input tax rate and employee contribution amount.
- Real plans can include vesting rules, contribution caps, and country-specific tax treatment.
