Everyday calculators for Spain 2026
Not every calculator is about taxes or salary. This category brings together the daily-use tools that save time in everyday situations. The EBAU calculator applies your Autonomous Community's weightings to compute the university access mark: 60% bachillerato + 40% general EBAU phase, plus up to 4 extra points from the specific phase. The tip calculator splits the bill fairly among any number of diners at your chosen percentage.
This category spans the Ministerio de Universidades (EBAU), the International System of Units (SI) (conversions), and universal mathematical standards (geometry, fractions, rule of three).
People commonly ask: how do I calculate my EBAU score?, how many drinks do I need for my party?, or how do I convert km to miles? Simple questions with answers that are sometimes less obvious than they appear.',

What to watch out for
EBAU cut-off marks change every year โ always check the previous year's mark, not historical lows
University entry marks published for each EBAU sitting refer to the previous year and change every year as demand fluctuates. A 8.5 mark may be enough for a degree one year but not the next if demand rises. Check the official cut-off published by the Autonomous Community where you will apply, not just national averages.
Tipping is optional in Spain โ 10% is the accepted standard in restaurants
Unlike the US, tipping in Spain is never mandatory and not expected in every setting. In mid-to-upper-end restaurants, 10% of the bill is the accepted standard for good service. In tapas bars or cafรฉs, tipping is rare. In hotels, porters and room service staff typically receive โฌ1โโฌ2 per service.
A secure password needs at least 16 characters mixing upper, lower, numbers, and symbols
INCIBE (Spain's National Cybersecurity Institute) recommends passwords of at least 12โ16 characters mixing uppercase, lowercase, numbers, and symbols. A 16-character random password would take trillions of years to crack by brute force. Never reuse passwords across services โ use a password manager.
Road distance between cities is 20โ40% longer than straight-line distance
Straight-line (haversine) distance is always shorter than road distance. Madrid to Barcelona: straight line ~505 km, fastest road ~621 km (23% longer). For travel time estimates, always use road distance and allow an average of 100 km/h on motorways with extra time for urban sections.

Frequently asked questions
How is the Spanish university entry mark (nota de acceso) calculated in 2026?
The university access mark is: 60% of the bachillerato average + 40% of the EBAU general phase score. With the specific phase (degree-related subjects), up to 4 additional points can be added, giving a maximum of 14 points. Each Autonomous Community applies its own subject weightings. The EBAU calculator applies the weightings for your community.
How do I calculate my Spanish university GPA for a master's application?
Multiply each subject grade by its ECTS credits, sum the results, and divide by total credits. The numerical Spanish scale (0โ10) is sometimes converted to a 0โ4 scale: Distinction/Honours = 4, Notable = 3, Aprobado = 2, Suspenso = 0. The university GPA calculator handles both scales.
How many drinks do I need for a party of 50 people?
A general rule: 1 bottle of wine per 3โ4 people for a 3-hour dinner, or 2โ3 beers per person. For 50 guests at a 4-hour party: plan on 12โ15 bottles of wine, 100โ120 beers, and 10โ15 litres of soft drinks. The drinks calculator adjusts by event type and duration.
How many human years is a 7-year-old dog?
The simple "multiply by 7" rule is inaccurate. AKC-aligned research shows the first 2 years of a dog's life equal approximately 25 human years total, with each subsequent year adding roughly 5โ7 human years depending on breed size. A 7-year-old dog is approximately equivalent to a 45โ55-year-old human. The dog age calculator uses the AKC model.
How does the Secret Santa draw work for large groups?
Secret Santa (Amigo Invisible) randomly assigns who gives a gift to whom, ensuring no one is assigned to themselves. For large groups with restrictions (couples who can't give to each other, team members, etc.), a manual draw can be impossible. The Secret Santa generator handles up to 50 participants with pair exclusion rules.
