SAR (Stock Appreciation Rights) Calculator
SAR exercise value.
Calculate SAR (Stock Appreciation Rights) cash value at exercise. Enter sar units and grant price to see sar cash value from units and grant price.
What this tool does
This calculator estimates the current exercise value of Stock Appreciation Rights by computing the gain per unit and multiplying by your vested portion. It takes four inputs: the number of SAR units granted, the original grant price, today's share price, and the percentage of units that have vested. The result shows what cash you could receive if you exercised your vested SARs at the current price. The calculation treats any gain below zero as zero—SARs have no value if the share price hasn't risen above the grant price. This tool assumes immediate exercise with no tax effects, transaction costs, or future price movements. It's useful for modeling scenarios where share price changes, helping you understand how appreciation translates into monetary value at different price points. The output is illustrative only.
Quick answer: with the default values, the result is $15,000.00 (SAR Cash Value). Adjust the values below for your own figures.

SARs (Stock Appreciation Rights) pay employees the appreciation in share price between grant and exercise, in cash. Like options without the strike price purchase. Granted at current price. Vest over time (typically 4 years). Exercise: receive (current price - grant price) × units in cash. Common alternative to options at private companies and some public.
1,000 SAR units at 20 grant price. Current price 35. Appreciation 15/unit × 1,000 × 100% vested = 15,000 cash value. Taxed as ordinary income at exercise. No share purchase needed (unlike options) - direct cash payout. Simpler than options for both employee and employer.
SAR vs RSU: RSU = receive shares (taxed at vest based on share value). SAR = receive cash equal to appreciation (taxed at exercise based on appreciation). RSU value rises with all share movement; SAR only rises with appreciation above grant. SAR riskier: if share price stays flat, value zero. RSU always has some value if shares non-zero. Most companies use RSUs; SARs more common at private companies pre-IPO.
Run it with sensible defaults
Using sar units of 1,000, grant price of 20, current share price of 35, vested of 100%, the calculation works out to 15,000.00. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — SAR Units, Grant Price, Current Share Price, and Vested % — do not pull with equal force.
How the math works
Appreciation per unit = current - grant (min 0). Value = appreciation × units × vested %.
Where this fits in planning
This is a "what-if" tool, not a forecast. It helps to test ideas: what happens to the result as the SAR Units or the Grant Price changes. The value is in the scenarios you run, not the single answer you get from the defaults.
1,000 units × (£35 - £20) × 100% = $15,000.00.
Inputs
| Per-Unit Appreciation | $15.00 |
|---|---|
| Vested Units | 1,000 |
| Grant Price | $20.00 |
| Current Price | $35.00 |
This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.
Sources & Methodology
Methodology
The calculator computes the intrinsic value of vested stock appreciation rights by determining the per-unit appreciation and scaling it to your vested holding. It subtracts the grant price from the current share price to find appreciation per unit, treating any negative result as zero (rights have no value if the share price has not exceeded the grant price). This per-unit appreciation is then multiplied by the total number of SAR units and the vested percentage to derive the total exercisable value. The model assumes a linear vesting schedule and does not account for forfeiture conditions, trading restrictions, liquidity constraints, tax withholding obligations, exercise fees, or changes in share price after the calculation date.
