How China's Maternity Allowance Is Actually Calculated (生育津贴) — Leave Days, Wage Base, and the Numbers HR Won't Volunteer
China's maternity allowance equals the employer's average monthly contribution wage divided by 30, times your maternity-leave days, plus a medical reimbursement. Here is how it works.
How China's Maternity Allowance Is Actually Calculated (生育津贴)
The first thing almost everyone gets wrong about China's maternity allowance (生育津贴) is whose salary it is based on. People assume it tracks their own paycheck. It does not. The allowance is computed from the employer's average monthly contribution wage — the 单位上年度月平均工资 reported to the social insurance fund — and that single fact changes whether you come out ahead or behind during leave.
This post walks through the real formula, why leave days swing from 128 to 365 across provinces, and a worked example you can reproduce in the China Maternity Benefits Calculator. Everything below is built from the 2025 provincial 人社厅 and 卫健委 notices, and the disclaimer that applies to every word: actual disbursement follows your local 社保局 approval, not any online estimate.
The formula, written out
There are two payouts bundled under "maternity benefits," and they are computed separately.
The first is the maternity allowance itself:
maternity allowance = 单位上年度职工月平均工资 ÷ 30 × 产假天数
So there are exactly two levers: the company's average monthly contribution wage, and the number of maternity-leave days. Divide the monthly wage by 30 to get a daily rate, multiply by the leave-day count, and that is the allowance the social insurance fund pays. In most provinces the fund pays the employer, and the employer disburses it to you as your in-leave wage; a few provinces pay you directly.
The second payout is the lump-sum medical reimbursement — a flat figure that depends on birth type (vaginal, caesarean, or first-trimester miscarriage). It is small relative to the allowance, usually in the low thousands of RMB, and it stacks on top.
The lever that surprises people is the first one. If your personal salary is higher than the company average, the fund pays the lower number, and most provinces require the employer to top up the difference (单位补差). If your personal salary is lower than the company average, the allowance is larger than your normal paycheck — and you keep all of it. The employer cannot claw it back.
Why leave days differ so wildly by province
National law sets the floor at 98 days under the 2012 Female Workers Special Protection Regulations. On top of that floor, each provincial People's Congress passes its own 人口与计划生育条例 that adds a reward bracket. After the 2021 three-child reform, nearly every province raised that bracket.
A few concrete anchors from the calculator's 2025 table:
- Beijing, Shanghai, Hubei: +60 days → 158 total
- Guangdong, Anhui, Heilongjiang: +80 days → 178 total
- Tibet: a flat 365 total
- Hainan: 195 for the third child
Birth complications stack on the national base before any provincial reward. National law adds 15 days for dystocia (难产, which most provinces read to include caesarean) and 15 days per additional baby in a multiple birth. So a twin caesarean at the national floor is 98 + 15 + 15 = 128 days, before the province's reward days are added.
This is exactly why a pre-2021 leave-days table will quietly underpay you. If your reference says Beijing is 128 days, it is out of date — the current figure is 158.
A worked example
Take a Beijing employee. Her company's 上年度 average monthly contribution wage is ¥9,500. She has a straightforward first-child vaginal birth, so her leave is Beijing's 158 days (98 base + 60 reward, no complication days).
Run the formula:
9,500 ÷ 30 = ¥316.67 per day 316.67 × 158 = ¥50,033
That ¥50,033 is the maternity allowance. Add the vaginal-birth medical reimbursement (a low-thousands flat figure in Beijing) and you have the full benefit.
Now suppose her personal salary is actually ¥18,000/month. Her normal income across those 158 days would be 18,000 ÷ 30 × 158 ≈ ¥94,800. The fund only pays ¥50,033 — so the ¥44,000-odd gap is precisely what 单位补差 is meant to cover in most provinces. Without seeing that number written down, most people accept whatever HR quotes. With it, you have a specific claim to bring to the conversation.
Push the example harder: a twin caesarean in Sichuan is 98 + 15 (dystocia/caesarean) + 15 (extra baby) + 60 (Sichuan reward) = 188 days. At the same ¥9,500 company average, the allowance alone is 9,500 ÷ 30 × 188 ≈ ¥58,900, plus a caesarean medical reimbursement on top.
The first time I ran my own numbers
I'll be honest about why this tool exists. When a colleague went on leave, she told me her HR had quoted a figure that "felt low," but neither of us could say why with any confidence. We sat down, pulled the company's reported average wage off her 社保缴费基数 申报表, counted the leave days from her province's ordinance, and did the division by hand. The number we got was meaningfully higher than the quote — the difference was the 单位补差 her employer had simply not mentioned. She went back with the worked figure, and the gap was honored. That afternoon convinced me the math itself is trivial; the hard part is knowing the average-wage base and the current leave-day count, and trusting the result enough to ask.
The cases where the allowance route is closed
One scenario trips people up: 灵活就业 (self-employed flexible-worker) social insurance. In most provinces, the flexible-worker scheme does not carry maternity insurance, so the allowance path is closed entirely. What remains open is the medical-fee reimbursement through 城乡居民医保, on a flat-rate basis. If you are in this category, set the employer-insured toggle off in the calculator to see the version that zeroes the allowance and shows only the reimbursement — the realistic number for a freelancer.
The same toggle covers a darker case: an employer that never registered you for maternity insurance at all. Under the 2025 unified Social Insurance Law, that employer must pay the entire allowance and reimbursement out of pocket, on the standard the fund would have used. The tool's number becomes the employer's minimum liability, and in some provinces you can pursue 劳动仲裁 for that amount plus punitive damages.
Where this fits in your wider planning
Maternity benefits are one line in a larger household cash-flow picture for the year you have a child. Two adjacent tools on Toolora pair naturally with this one. If you are mapping out the tax side of the same year, the China personal income tax special deduction simulator covers the child-rearing and education deductions that arrive right after the birth. And if you are still pinning down dates, the pregnancy due date calculator gives you the delivery window that determines exactly when the leave clock — and the allowance — begins.
Two documents are mandatory in every province for the official claim: the discharge summary (出院小结) and the birth certificate (出生医学证明). Save the originals. Use the calculator to sanity-check what HR tells you, to decide whether to press for 单位补差, and to estimate the cash-flow gap across the leave window before it arrives — not to file the claim itself, which goes through 12333 or your employer's HR.
