试用期到底能约定多久：分档规则与三个高频坑
上限由合同期限决定，分四档。《劳动合同法》第十九条：合同期限 3 个月以上不满 1 年，试用期不超过 1 个月；1 年以上不满 3 年，不超过 2 个月；3 年以上固定期限和无固定期限，不超过 6 个月；不满 3 个月或以完成一定工作任务为期限的，不得约定试用期。页面按你填的期限直接判定，并和合同里实际约定的试用期做合法性对照。
坑一：「只约定试用期」的写法等于没有试用期。第十九条第三款：试用期包含在劳动合同期限内；劳动合同仅约定试用期的，试用期不成立，该期限就是劳动合同期限。也就是说签了份「3 个月试用期合同」，法律上它是 3 个月的正式合同，不存在试用期。
坑二：试用期工资有双重下限。第二十条：试用期工资不得低于本单位相同岗位最低档工资或者劳动合同约定工资的 80%，并不得低于当地最低工资标准——两个条件取高者。合同 8000 元、当地最低工资 2500 元时，试用期至少 6400 元；按 70% 甚至 50% 发工资都是违法的。
坑三：超期的试用期要「补钱」。同一用人单位与同一劳动者只能约定一次试用期（调岗、续签都不能重约）。约定的试用期超过法定上限的，超出部分无效；已经履行的，按第八十三条由用人单位以转正后月工资为标准，支付超过法定试用期期间的赔偿金。页面在你约定超期时自动折算。

FAQ
Under Article 19 of the Labour Contract Law: for a contract of three months up to one year, probation may not exceed one month; from one year up to three, not two months; for fixed terms of three years or more and open-ended contracts, not six months. Contracts under three months, or task-completion contracts, may not stipulate a probation period at all.
Under Article 20: the probation wage may not be below 80% of the lowest wage step for the same position at the unit, or of the wage agreed in the contract - and may not fall below the local minimum wage. Take the higher of the conditions: with a contract wage of 8,000 and a local minimum of 2,500, the probation wage must be at least 6,400.
The excess is void. Under Article 83, where an agreed probation has already been performed beyond the legal limit, the employer pays compensation for the period beyond the statutory probation, computed at the employee's full monthly wage - the wage after becoming permanent.
No. The same employer and the same employee may stipulate probation only once; a contract that stipulates only a probation period means no probation comes into being - that term simply is the contract term; and probation is contained within the contract term. A transfer or a renewal with the same employer can neither restart a probation.
No. Contract terms and wage figures only take part in computation inside your browser: the page makes no network requests, writes nothing to localStorage, cookies or URL parameters, and reloading clears it. This is a statute-based estimate and is not legal advice.
