Direct answer: To save for the deposit of a home from scratch you need three steps: calculate how much you really need (property price × 20% deposit + 10-12% expenses), audit your current expenses to identify how much you can save each month, and automate that saving so it is systematic and not optional. With discipline and the right tools, many young people achieve the goal in 4-7 years. It is also possible to borrow more than 80% — but that comes at a real cost worth understanding before you apply.
Learning how to save for the deposit of a home from scratch is the first major financial challenge for many young Spaniards. Banks finance a maximum of 80% of the appraisal value, which means you need to have available the remaining 20% plus the purchase expenses (notary, registry, taxes), which amount to an additional 10-12%. In total: between 30% and 35% of the property price before signing.
How much money do you really need? Example with round numbers
The most common mistake is calculating only the 20% of the price and forgetting the expenses. Three typical scenarios for Spain:
- Flat at €150,000 (medium-sized city, outskirts): Down payment 20% = €30,000 · Costs (ITP + notary + registry) ≈ €15,000-18,000 · Total required: €45,000-48,000
- Flat at €200,000 (large city, average neighbourhood): Down payment 20% = €40,000 · Costs ≈ €20,000-24,000 · Total required: €60,000-64,000
- Flat at €300,000 (Madrid, Barcelona, prime areas): Down payment 20% = €60,000 · Costs ≈ €30,000-36,000 · Total required: €90,000-96,000
According to data from Idealista, the average price of housing in July in Spain is of €2.933/m², with large variations by region — Madrid and the Balearic Islands exceed €5,000/m².
How long will it take you to save the deposit? Quick simulation
With a monthly savings goal and the required capital, the timeline is purely mathematical. Example for a €200,000 flat (target: €60,000):
- Saving €500/month → 120 months = 10 years
- Saving €700/month → 86 months = ≈7 years
- Saving €1,000/month → 60 months = 5 years
- Saving €1,500/month → 40 months = ≈3.5 years
If you also place the money in a high-yield account at 2.5% APR, the timeline shortens by 6-12 months depending on the amount. Use the monthly budget planner to calculate your exact scenario and see in which month you reach your target.
The 80% rule: why banks do not finance 100%
Retail banks restrict their lending to 80% of the appraised value or the purchase price (whichever is lower) as risk policy. The logic is simple: if the owner has contributed 20% from their own pocket, they have a buffer that makes default less likely and ensures the bank recovers the asset in case of foreclosure. For you, this means the 20% down payment is non-negotiable with most lenders… under standard conditions.
Can you borrow more than 80%? Yes, but with important caveats
There are three routes to access financing above 80%:
- Very solvent borrower profile: Some banks offer up to 90% (or even 100% in exceptional cases) to clients with very high incomes, stable employment, no other debts and guarantors. This is the exception, not the rule.
- Regional and national government schemes: Programmes like ICO State Guarantee allow the government to guarantee up to 20% of the mortgage, freeing you from providing that portion. The usual conditions are that it is your first home, that the price does not exceed a certain threshold (usually €250,000-300,000) and that your income is below a ceiling (around €37,800/year gross in 2024).
- Youth mortgages from certain regional governments: Catalonia, Madrid, Andalusia and Valencia have their own guarantee schemes that complement or replace the national ICO guarantee.
The key point banks rarely explain clearly: more financing = higher rate = larger monthly payment
When a bank offers you 90% instead of 80%, it is not doing so out of generosity — it is taking on more risk, and that risk has a price in the form of a higher interest rate. The bank's reasoning is straightforward: someone who needs to borrow 90% has less savings and therefore a higher credit risk profile. The higher the perceived risk, the higher the spread applied.
The real impact in numbers, for a €200,000 flat over 30 years:
- 80% mortgage (€160,000) at 3.0% fixed TIN: Monthly payment ≈ €675 · Total paid: ~€243,000
- 90% mortgage (€180,000) at 3.5% fixed TIN (bank raises rate due to higher risk): Monthly payment ≈ €808 · Total paid: ~€291,000
- 95% mortgage (€190,000) at 4.0% fixed TIN (even higher risk): Monthly payment ≈ €907 · Total paid: ~€326,000
The difference between 80% and 95% is €232 more per month and more than €83,000 in total interest over the life of the loan. Saving the 20% takes longer upfront, but is enormously cheaper in the long run.
How to save for the deposit from scratch: the step-by-step method
Step 1: Audit your current expenses
You cannot save what you do not control. Categorise all your expenses from the last month into: fixed (rent, electricity, internet), variable necessary (food, transport) and variable discretionary (leisure, subscriptions, meals out). The saving potential is in the third category.
- Use bank statements from the last 3 months to get a real picture.
- Identify recurring expenses you have forgotten (forgotten subscriptions, over-priced insurance).
- Calculate your current saving rate: monthly saving ÷ net income × 100. Use the net salary calculator to get your exact take-home pay. Use the net salary calculator if you are an employee.
Step 2: Define your goal and deadline
With the total target calculated (e.g. €60,000) and your real monthly saving capacity (e.g. €700/month), you can calculate the deadline: 60,000 ÷ 700 = 85 months ≈ 7 years. If the deadline is too long, you have two levers: increase income or reduce the goal (look for a more affordable area). The Uselium Monthly Budget Planner allows you to categorise expenses, set a saving goal and automatically see in which month you reach the deposit target.
Step 3: Automate the saving
Manual saving does not work in the long term. Set up an automatic transfer on the same day you receive your salary towards a separate savings account. What you do not see, you do not spend. Minimum goal: save 20% of your net income.
- High-yield savings account: currently the best offers give between 2% and 3% APR.
- Money market funds: alternative for larger amounts, with liquidity in 2-3 business days.
- Do not invest in equities money you will need in less than 5 years — market risk can delay your goal.
Step 4: Accelerate saving with additional income
Reducing expenses has a limit — increasing income does not. Concrete options: negotiate a raise, change company, do freelance work in your area of specialisation, or sell objects you no longer use. Each extra €100 per month is €1,200 more per year — over 5-6 years, that is €6,000-7,200 extra on top of your base plan.
Mistakes that delay entry into the property market
- Saving what is left over instead of spending what remains after saving.
- Keeping the money in a current account without interest when there are alternatives offering 2-3% APR.
- Calculating only the down payment and forgetting the purchase costs (additional 10-12%).
- Assuming 90% financing is free — the higher rate more than offsets the benefit of not having to accumulate the full 20%.
- Not reviewing the goal periodically — market prices change and your deadline may need adjustment.
Conclusion: discipline is your most valuable asset
Knowing how to save for the deposit of a home from scratch is the easy part. Executing it for 5-7 years with discipline is the real challenge. The automation of saving, monthly tracking of real progress and the use of tools that give you visibility are what separate those who achieve it from those who are always "about to start". And remember: borrowing more than 80% is possible, but expensive. Every month you spend accumulating that 20% is money you will not pay in interest over the next three decades. Start today.
