How buyout is usually computed
Most employment contracts base the buyout on basic salary rather than gross, multiplied by the unserved portion of the notice period. Some organisations use gross salary, and a few use cost to company, which produces a substantially larger figure. The contract governs, and the difference between basic and CTC can be double or more, so read the specific clause rather than assuming the common case.
Check what offsets the amount
Accrued unused leave is often encashable and can be set against the buyout. Any pending reimbursements, bonus already earned, or final salary for days worked also reduce the net payable. In many cases the practical amount owed after these offsets is considerably smaller than the headline buyout figure, and it is worth calculating the net position before negotiating.
Who pays
Where an employer is actively recruiting for a hard-to-fill role, buyout reimbursement is a common and negotiable part of an offer. It is worth raising explicitly during negotiation rather than after acceptance, because once you have signed, the leverage is gone. Some employers reimburse fully, some cap it, and some structure it as a joining bonus with a clawback if you leave within a period, which is a different arrangement with its own risk.
Enforceability varies
Notice periods are contractual, and whether a buyout clause is enforceable depends on jurisdiction and on whether the amount is a genuine estimate of loss rather than a penalty. Courts in several jurisdictions have struck down clauses that function punitively. Employers also cannot generally withhold a relieving letter or experience certificate as leverage, though in practice this happens and is a common pressure point.
Serving versus buying out
Serving the notice preserves the relationship and the reference, and costs nothing. Buying out costs money and starts the new role sooner. Where the new offer includes a materially higher salary, the difference often covers the buyout within a few months, which is the calculation worth running before deciding.

Frequently Asked Questions
Is buyout calculated on basic or gross salary?
Most contracts use basic salary, some use gross, and a few use cost to company, which can double the figure. The contract clause governs, so read it rather than assuming the common case.
Can unused leave offset the buyout?
Often yes. Encashable accrued leave, pending reimbursements and salary for days worked all reduce the net payable, and the practical amount owed is frequently much smaller than the headline figure.
Will a new employer pay my buyout?
Frequently, for hard-to-fill roles, and it is negotiable. Raise it before accepting the offer, since leverage disappears afterwards. Watch for arrangements structured as a joining bonus with a clawback period.
Is a buyout clause always enforceable?
Not necessarily. Enforceability depends on jurisdiction and on whether the amount reflects genuine loss rather than functioning as a penalty. Courts in several jurisdictions have struck down punitive clauses.
Should I serve the notice instead?
Serving costs nothing and preserves the reference. Buying out costs money but starts the new role sooner. Where the new salary is materially higher, the increase often covers the buyout within a few months.
