AIS Calculator (Automated Investment Score)
Estimate your AIS using income, expenses, savings, investment return, and timeline. This score helps you gauge how ready your finances are for long-term wealth building.
AIS is an educational planning metric, not investment advice.
What is an AIS calculator?
In this article, AIS stands for Automated Investment Score. It is a practical score (0 to 100) designed to summarize three important personal-finance strengths in one view:
- Your monthly savings behavior
- Your short-term stability (cash runway)
- Your long-term growth setup (time horizon and expected return)
A single score should never replace full financial planning, but it can make it much easier to track progress month to month.
How this AIS calculator works
1) Monthly surplus
The calculator first estimates your monthly surplus: monthly income − monthly expenses. This tells you whether you are building capacity to invest every month.
2) Future value projection
It then projects your savings growth using monthly compounding. The model combines:
- Growth of your current savings balance
- Growth of ongoing monthly contributions (your surplus)
This gives a forward-looking estimate of where your portfolio may land after your selected number of years.
3) Score components
The AIS score blends:
- Savings Rate Score (up to 40 points)
- Runway Score based on months of expense coverage (up to 25 points)
- Growth Setup Score from timeline and expected return (up to 35 points)
If monthly surplus is negative, a penalty is applied because sustained investing is much harder without positive cash flow.
How to read your AIS result
- 0–39: Fragile. Focus on budgeting, debt reduction, and emergency buffer.
- 40–59: Improving. You have momentum but need stronger consistency.
- 60–79: Strong. Good structure with room to optimize.
- 80–100: Excellent. Solid financial engine and long-term compounding potential.
Example scenario
Suppose you earn $6,000/month, spend $3,900/month, already have $20,000 invested, expect 7% annual return, and stay invested for 20 years. You will likely see:
- A healthy monthly surplus
- Several months of financial runway
- A strong projected portfolio from long-term compounding
- An AIS score in the strong-to-excellent range
If you increase the horizon to 30 years, the projected future value often rises dramatically—even without changing income. Time is one of the most powerful factors in wealth creation.
Ways to improve your AIS quickly
Increase savings rate
Reduce recurring expenses by 5–10% and redirect the difference to automated investments. Small improvements in monthly surplus can produce large long-run effects.
Build runway first
Before aggressively investing, target at least 3–6 months of essential expenses in a liquid emergency fund. This improves stability and helps prevent panic withdrawals.
Protect your timeline
The longer money stays invested, the stronger compounding becomes. Try not to interrupt your plan for short-term market noise.
Important limitations
This AIS calculator is a planning aid. Real-world results vary based on taxes, fees, inflation, market volatility, and behavior. Use this as a directional tool, then refine your plan with a full budget and, if needed, a qualified advisor.
