Estimates only. Not financial advice.
Heads-up: under-withholding. Your employer withholds federal tax at the IRS supplemental rate (22.0% on this vest, ≈ $17,600). Your marginal federal rate on this vest is 32.7%, owing $26,171. Expect to settle the $8,571 gap at tax time.
The hidden purchase
Tax was paid at vest either way. Holding is mathematically equivalent to taking $44,509 in after-tax cash and buying $44,509 of KVYO today.
Most diversification frameworks would advise against a purchase that size in a single name; the right answer depends on your conviction in KVYO. Holding past one year converts the gain to LTCG.

Best payout| Vest value (shares × price) | $80,000 |
| Federal | |
| State | |
| Medicare | −$1,160 |
| Additional Medicare | −$720 |

| Cap-gain tax on diversified gain — LTCG (federal + state + NIIT) | −$1,251 |
| Net at year 1 yr | $47,709 |
Sell every share at vest; invest the after-tax cash at the market return for 1 yr, then liquidate. Diversified — no single-stock concentration risk.
Hold 1 yr
| Vest value (shares × price) | $80,000 |
| Vest tax (federal + state + FICA) | |
| Net at year 1 yr | $42,728 |
Sold 444 shares to cover vest tax (net-settled); kept 556 shares 1 yr to qualify for long-term capital gains.
Social Security + Medicare are payroll taxes (collectively called FICA) — they apply because you're still employed at vest.
Both columns are stated in year-1 yr dollars. The sell side compounds at the market return; the hold side compounds at your single-stock expected return after a 20% volatility drag.
Estimates only. Assumes net-settled (sell-to-cover) vesting; double-trigger and pre-IPO RSUs are out of scope. Excludes multi-state moves, AMT interactions on other equity, and 83(b) elections. Not financial advice.
You evaluated one RSU vest. The beta plans every vest of every grant across years, with concentration and AMT in the loop.

Equity comp at Klaviyo
- RSUs use single-trigger vesting: shares become yours as each portion vests on schedule, and the value is taxed as ordinary income at that point. No IPO or acquisition is required.

Klaviyo (KVYO) RSUs vest as ordinary income at the price on vest day. The decision is whether to sell at vest and reinvest, or hold the shares through the 12-month LTCG cliff. This calculator runs both paths through the same after-tax math so you can compare like-for-like.
Example: 500 Klaviyo (KVYO) RSUs vesting at $13.84 per share is $6,920 of ordinary income on vest day. After roughly 32% combined federal + state + FICA (~$2,214), the post-tax share value is ~$4,706. Holding 12 months for long-term capital-gains treatment then only matters for the price change between vest and sale; the ordinary income at vest is already locked in. The calculator runs both paths through the same after-tax math.

Klaviyo equity questions
- Should I sell or hold my Klaviyo RSUs at vest?
- Klaviyo restricted stock units (RSUs) are taxed as ordinary income on their value at vest whether or not you sell. The only open decision is what to do with the shares afterward: sell at vest and reinvest, or hold past twelve months for long-term capital-gains treatment on any further gain. The calculator above runs both paths through the same after-tax math so you can compare them directly.
- Does Klaviyo grant ISOs, NSOs, or RSUs?
- Equity compensation at Klaviyo typically takes the form of incentive stock options (ISOs), non-qualified stock options (NSOs), and restricted stock units (RSUs). Incentive stock options can trigger the alternative minimum tax (AMT) when you exercise. Restricted stock units are taxed as ordinary income when they vest.
- Do Klaviyo RSUs use double-trigger vesting?
