RSU vs Stock Options: Which Is Worth More?
RSUs are generally worth more in stable or mature companies because they always hold value once vested. Stock options can be worth more at high-growth startups, since a low strike price combined with a rising stock price can multiply gains far beyond what RSUs would deliver, but only if the stock goes up. Use the #1 Share Incentive Plan Calculator to calculate the worth of your shares.
What are RSUs?
Restricted stock units are a promise from your employer to give you actual shares once they vest; no purchase is required. Because RSUs always have value, they're considered the safer form of equity compensation.
You don't pay anything to receive them
They convert to real shares on a set vesting schedule
Taxed as ordinary income the moment they vest
What Are Stock Options?
Stock options give you the rightto buy company shares at a fixed price called the "strike price" regardless of where the stock trades later.
You must pay to exercise them. Their value only exists if the stock price rises above your strike price, and it can expire worthless if the company underperforms.
ISO vs. NSO: Two Types of Options
Not all options are taxed the same way. ISO vs NSO is the first distinction to understand:
ISOs (Incentive Stock Options): Potential favorable tax treatment, but only for employees, with holding-period rules
NSOs (Non-Qualified Stock Options): Simpler rules, but taxed as ordinary income at exercise

RSU Vesting Explained
RSU vesting explained simply: your company sets a schedule during which your shares gradually become yours.
Understanding Your Vesting Schedule Calculator
Using a vesting schedule calculator helps you see:
How many shares vest each quarter or year
What your shares are worth at today's price
What happens if you leave before full vesting
How to Value Stock Options
It comes down to one core comparison: current stock price minus your strike price, multiplied by the number of options.
Stock Option Strike Price Basics
Your stock option strike priceis fixed at the grant. If the stock price later exceeds that number, your options are in the money. If it stays below, they're worth nothing until the price recovers.
Stock Option Exercise Cost
Don't forget the stock option exercise cost you may need to pay out of pocket to convert options into shares, plus taxes, before you see any actual money.
RSU Tax Treatment vs Stock Options Tax Implications
RSU tax treatment is straightforward: ordinary income tax is due the moment shares vest, based on their value that day.
Stock options tax implications are more layered:
NSOs: taxed as ordinary income at exercise
ISOs: potentially taxed only at sale, but may trigger AMT (Alternative Minimum Tax)
RSU vs Options for Startups vs Established Companies
RSUs vs. Options for Startup Employees
At an early-stage company, stock options for startup employees often make more sense; low strike prices mean higher upside if the company grows.
Equity Compensation for Tech Employees at Big Companies
At larger, publicly traded firms, equity compensation for tech employees usually favors RSUs, since the stock is already stable and liquid.
Frequently Asked Questions
Are RSUs or stock options better for employees?
It depends on company stage and risk tolerance. RSUs are better for employees who want guaranteed value once vested, while stock options suit those willing to bet on a rising stock price at a growth-stage company.
How does RSU vesting work?
RSU vesting typically follows a 4-year schedule with a 1-year cliff, meaning no shares vest until year 1; vesting then continues quarterly or annually.
What happens to stock options if I leave the company?
Most companies give you a limited exercise window, often 90 days, to buy vested options before they expire. Unvested options are usually forfeited immediately.
Do RSUs or stock options get taxed differently?
Yes. RSUs are taxed as ordinary income at vesting, while stock options depend on type NSOs at exercise and ISOs potentially at sale, subject to AMT rules.
How can I calculate which equity type is worth more?
The easiest way is to use an RSU calculator alongside a stock options calculator, entering your strike price, current share price, and vesting timeline to compare real dollar outcomes side by side.
