How the simulator calculates

Independent site: not the Ministry of Education, handles no applications

Every sum runs in your browser with rules written from three texts, re-read on 8 November 2026: Royal Decree 179/2026, published on 12 March 2026; the consolidated Royal Decree 1721/2007; and the full text of the call of 23 March 2026, downloaded from the National Grants Database. What you type never leaves your device.

The order of the rules

The simulator follows the Ministry's order. First, family income against the thresholds in article 8 of the Royal Decree, by household size, using the lower end of each range, which is what the call applies in its article 19; being exactly on a threshold counts as not exceeding it. Second, wealth: the sum of percentages in article 20 of the call and the €172,000 business limit. Third, the academic requirement in articles 24, 26, 29, 33 and 34. If all three are met, the components matching your studies, threshold, enrolment and mode are added up, under articles 3 and 4 of the Royal Decree and 5 to 13 of the call.

What is exact and what is not

Fixed amounts are exact: €1,700 income-linked, €2,700 residence, €300 basic grant, excellence by band, island supplements and disability increases. The variable amount cannot be calculated: it depends on leftover money, the number of holders and the top-decile grade in each field, figures only the Ministry knows at the end. The simulator shows the €60 minimum and says so in every result. The tuition waiver depends on each region's price per credit, which we have not collected: the tuition calculator asks for yours.

Stated simplifications

The main simulator sums up the academic requirement as a grade and a pass rate; the requirements calculator applies the full exceptional-performance formula. Full-orphan status is applied to income after other deductions. Working-day deadlines skip Saturdays and Sundays but not holidays, which vary by region and town. The Basque and Catalan calls are not calculated, nor is aid for students with specific educational support needs.

Tests

The rules have automated tests with cases taken from the text: threshold 1 for five members (€25,644), income exactly on the threshold, a flat revalued in 2010 with its coefficient, the 7.5 in engineering that reaches excellence after the coefficient, part-time enrolment of 48 credits, a one-month deadline ending on a Saturday. The site does not build if a test fails.

Updates

Each year brings a new royal decree and a new call. We re-read both by hand when they appear in the Official Gazette; there is no automatic update. Until then, the figures are those for 2026-2027 and say so. If you spot an error, write via contact; how we correct is in the editorial policy.
