The grant's variable amount: the formula and your weight
Independent site: not the Ministry of Education
Enter your average grade, family income and household size: the calculator applies the official formula as far as it can and gives your relative weight in the share-out.

Your weight in the share-out (Nj/Nmax) × (1 − Rj/Rmax)
0.358
Guaranteed minimum: €60. The rest depends on leftover funds and all other grant holders: the euro amount cannot be forecast.
| Grade factor Nj/Nmax | 0.75 |
| Per-capita income Rj | €5,000 |
| Income factor 1 − Rj/Rmax | 0.477 |
| Threshold reached | Threshold 1 |
Call, art. 10: Cj = Cmin + (Ctotal − S·Cmin) × weight / sum of weights. Ctotal, S and the sum are known only to the Ministry.

The variable amount is the only part of Spain's general study grant without a figure set in advance. Article 5 of Royal Decree 179/2026 says that, once every fixed amount and minimum has been paid, whatever money is left is shared among threshold 1 and 2 grant holders according to their average grade and their income, using the formula in article 9.2 of Royal Decree 1721/2007, which the call copies in its article 10. Each holder receives at least €60. The rest depends on three figures only the Ministry knows when the year closes: how much money is left, how many holders there are and the grade of the top ten per cent in each field. So nobody, this site included, can tell you what your variable amount will be. What can be worked out is your weight in the share-out: the higher your grade and the lower your income per person, the bigger your share. The decision comes after the fixed amounts: the call gives the Ministry six months from the date it has the regions' data.
The formula, term by term
Article 9.2 of Royal Decree 1721/2007 and article 10 of the 2026-2027 call share out the variable amount like this: each holder's amount is the €60 minimum plus a slice of the remaining money proportional to their weight. The weight multiplies two factors. The grade factor is your average divided by that of the top decile of holders in your field (Nmax). The income factor is one minus your per-capita income divided by the maximum per-capita income for the variable amount (Rmax).
| Term | What it is | Who knows it |
|---|---|---|
| Cmin | Minimum variable amount: €60 | Royal Decree 179/2026 |
| Nj | Your average grade, fails included | You |
| Rj | Your family income divided by members | You |
| Nmax | Average of the top 10% of holders in your field | Ministry, at the end |
| Rmax | Maximum per-capita income for the variable | Ministry |
| Ctotal and S | Money to share and number of holders | Ministry, at the end |
The call's total budget is 1,978 million euros, plus a further 450 million if needed, but what is left for the variable part is only known once all fixed amounts are taken off. University and non-university students are shared out separately, and jointly with Catalonia's grant holders.
Your weight in the share-out

What the calculator does and does not do
The calculator puts your grade and per-capita income into the formula. As the Ministry does not publish Nmax or Rmax before the share-out, it uses two assumptions you can see under "More about your case": a reference grade of 10 and a maximum income equal to threshold 2 divided by members. You can change them. The result is an index between zero and a little over one, useful to compare two situations, such as how much your weight rises if your average goes up a point. It does not turn it into euros: that would need Ctotal, S and the sum of every holder's weight.
For a rough euro figure, the Ministry offers its official variable-amount simulator, which when read was still set up with 2025-2026 data. Fixed amounts, on the other hand, are exact: see grant amounts and the full simulator.
One more detail affects the share-out: students who only receive the minimum, such as part-time or distance students, are left out when Nmax is calculated, so the reference grade reflects full-time holders only.
