What is the "calculator de alicia"?

The calculator de alicia is a simple idea: take one everyday expense, imagine investing that same amount regularly, and compare where you end up over time. Inspired by the famous "daily coffee" question, this calculator helps you see the long-term impact of small financial decisions.

Alicia's approach is practical and motivating. Instead of trying to cut everything, she focuses on one repeat expense and asks, "What if I redirected this into an investment account?" The answer can be surprisingly powerful because of compound growth.

How to use this calculator

1) Enter your daily amount

Start with something realistic: coffee, snacks, rideshares, subscription fees, or any expense that happens frequently. You do not need a huge number for this to work.

2) Add your expected annual return

This is your estimated average yearly growth. Many long-term stock-market scenarios use ranges between 6% and 10%, but your personal assumptions should be conservative and aligned with your risk tolerance.

3) Choose years and a goal

The longer your horizon, the bigger the compounding effect. Enter a target amount to see whether your current plan reaches that milestone and how long it might take.

What the calculator shows you

Total invested contributions: How much cash you personally put in.
Estimated future value: Contributions + growth from compounding.
Estimated gains: The portion generated by returns, not deposits.
Time to target: How long it may take to hit your goal amount.

The core formula (in plain language)

We convert your daily amount into an average monthly contribution, then apply monthly compounding. The model combines:

Growth of your starting balance
Growth of monthly recurring contributions

monthlyRate = annualRate / 12 months = years * 12 futureValue = (initial * (1 + monthlyRate)^months) + (monthlyContribution * (((1 + monthlyRate)^months - 1) / monthlyRate))

Example: the classic coffee scenario

If Alicia spends $5/day and redirects that into investments, that is roughly $152/month. Over decades, this can accumulate into a substantial amount, especially with steady returns. The key lesson is not "never buy coffee"—it is that repeated small actions become meaningful over time.

Best practices for real-life use

Automate contributions

Use automatic transfers so your plan runs without daily willpower.

Increase over time

Raise contributions after salary increases, bonuses, or debt payoffs. Small increases can dramatically accelerate progress.

Review assumptions yearly

Markets are unpredictable in the short term. Revisit return assumptions and goals once a year.

Common mistakes to avoid

Using overly optimistic return estimates
Ignoring fees, taxes, and inflation in long-term planning
Stopping contributions after market dips
Waiting too long to start

Final thought

The calculator de alicia is a mindset tool as much as a math tool. It turns abstract advice into concrete numbers. Whether your daily amount is $2 or $12, consistency and time can do more than most people expect.

Use this calculator as a planning guide, then build a routine you can stick with for years.
