Difference between 100% and 80%?

100% pays full income (up to 6G) for 49 weeks. 80% pays 80% for 59 weeks. Total pay is identical if income is below 6G. Above 6G, 80% pays less overall because the cap doesn’t rise. Many pick 100% for higher monthly cash flow. 80% suits those who want longer at home with a good buffer.

How much is the father’s quota?

15 weeks in the 100% model and 18 weeks in the 80% model (also called "quota 1"). This period is reserved for the father and can’t be transferred to the mother. The mother has a matching quota of the same length. The shared period of 16 weeks (100%) / 18 weeks (80%) can be split freely. The mother also gets 3 weeks before due date. The quotas aim to strengthen the father’s role in the child’s first year and reduce lopsided leave.

Can I work part-time during leave?

Yes. You can pick "gradert uttak" (graded leave) where you work reduced hours (e.g. 50%) and take 50% parental pay. The leave then stretches over twice as long. Or "utsette" (postpone), e.g. work full-time for a while and take the leave later. All leave must be used before the child turns 3. Apply on nav.no; the employer must agree to graded leave. This calculator shows standard full-time leave.

What if I don’t meet the earnings requirement?

You must have had wage or benefit income in at least 6 of the last 10 months before leave starts, above half of the base amount (0.5G, about 62,000 kr/year in 2024). Without qualification you get "engangsstønad" instead: about 92,000 kr (2024) tax-free lump sum per child. Students, long-term unemployed and new arrivals often land here. Also applied for via NAV.

Norwegian Parental Leave & Maternity Benefits Planner

How it works

Parental benefit from NAV is divided in three: a non-transferable quota for each parent, and a shared period you divide freely. In addition, 3 weeks before the due date are reserved for the parent giving birth. Choose 100% coverage (49 weeks) or 80% (59 weeks at a lower weekly rate).

Note: A simplified overview based on the main rule for two parents entitled to benefit. Special rules apply for single parents, multiples and adoption, see NAV for your situation.

About this tool

The parental-leave calculator helps you plan Norwegian NAV parental leave. Choose 100% coverage (49 weeks) or 80% (59 weeks), set the due date, and split the shared period between two parents. The tool shows father’s quota, mother’s quota and shared period in weeks and dates, so you can plan return-to-work, family logistics and finances. Applies to parents who meet the earnings requirement; single parents, adoption and multiples have separate rules. All local.

Examples

100% coverage, 50/50 split

Input100%, 49 weeks total (15+15+16 shared+3 pre)

OutputMother: 3 + 15 quota + ~8 shared = ~26 weeks. Father: 15 quota + ~8 shared = ~23 weeks

80% coverage, mother takes more

Input80%, 59 weeks (18+18+20 shared+3 pre)

OutputMother: 3 + 18 quota + 15 shared = 36 weeks. Father: 18 + 5 = 23 weeks

The 80% model pays the same total as 100%, spread over more weeks at a lower weekly rate. If your income exceeds 6G, you lose more on 80% because the cap is unchanged. Many pick 100% for higher monthly payment.

Common use cases

Planning when each parent returns to work.
Deciding whether 100% or 80% coverage suits the family.
Discussing shared-period split with your partner.

Technical background

Model uses NAV’s standard 3-part structure (May 2024). 100% coverage: 3 pre-term weeks for mother + 15 mother’s quota + 15 father’s quota + 16 shared = 49 weeks. 80%: 3 + 18 + 18 + 20 = 59 weeks. Shared split chosen via slider. Dates computed from due date: mother’s 3 weeks count backwards, the rest forwards. Payment: 100% or 80% of income basis capped at 6G (2024: 1G = 124,028 kr, 6G ≈ 744,168 kr). Simplification; does not handle single-parent, adoption, multiples, graded leave, premature birth, stillbirth or their special rules. See NAV Foreldrepenger for full rules.
