Short answer

How much should I save every month?

Your AI calculates a specific dollar amount for your 20% savings goal by analyzing your monthly income. You'll get a clear breakdown of your needs, wants, and savings targets.

The results.

Your budget breakdown.

The AI processes your income to produce these four specific outcomes.

SAVINGS

Target savings amount

The AI uses your income to set a hard 20% savings target. You get a single dollar amount to aim for.

NEEDS

Essential spending limit

The engine calculates 50% of your income for necessities. This shows you exactly what you have for rent, food, and bills.

WANTS

Discretionary spending cap

The AI sets a 30% limit for lifestyle spending. This tells you how much you can spend on fun without hitting your savings.

HUMAN

Manual adjustments

The AI provides the math, but you decide if these targets fit your actual life. You keep full control over your real bank transfers.

The workflow

What your AI does when the income data arrives.

The AI performs the math so you don't have to manually split your paycheck.

  1. Ingest income

    Your agent reads your current monthly income figures to establish a baseline.

    analyze_budget

  2. Apply 50/30/20 logic

    The engine splits that baseline into the three standard budget categories.

    analyze_budget

  3. Calculate savings target

    The AI isolates the 20% portion to give you a precise savings number.

    analyze_budget

  4. Output targets

    The agent presents the final dollar amounts for needs, wants, and savings.

FAQ

How this task behaves.

  • 01

    Can the AI move money into my savings account?

    No. The AI only calculates the target amounts. You must move the money yourself through your bank.

  • 02

    Does the AI change my actual budget files?

    No. The AI reads your data to perform the math, but it does not write or overwrite your original files.

  • 03

    What if my income changes every month?

    You just tell the AI your new income, and it will recalculate the new 50/30/20 targets immediately.

  • 04

    Can I use a different percentage than 20% for savings?

    No. This specific engine is built for the 50/30/20 rule and provides these exact deterministic targets.

  • 05

    Do I need to provide my bank login?

    No. You provide the income numbers or point the AI to a file you have already prepared.
