Short answer
How can I use AI to compare SAC and PRICE loans?
Your AI uses the calculate_amortization tool to run the math for both structures using your specific loan terms. You'll get a side-by-side look at how interest and principal change over time.
The outcomes
What you get from the comparison
The AI handles the heavy lifting of the math so you can focus on the decision.
DATA
Exact schedules
The AI generates full amortization tables for both SAC and PRICE models. You see exactly how much goes to interest every month.
ANALYSIS
Cost differences
The tool calculates the total interest paid for each structure. You'll see which option costs more over the life of the loan.
DECISION
Comparison views
Your agent organizes the data into a format that makes the differences obvious. You can pick the structure that fits your cash flow.
HUMAN
Final verification
You review the math and the logic. The AI provides the deterministic results, but you make the final call on the loan terms.
The workflow
What your AI does when the data arrives.
The AI stops guessing and starts calculating using deterministic math tools.
Input processing
Your agent takes your loan amount, interest rate, and term. It prepares these numbers for the math engine.
calculate_amortizationSAC calculation
The AI runs the math for a Constant Principal (SAC) structure. It builds the schedule where principal stays the same.
calculate_amortizationPRICE calculation
The AI runs the math for a Constant Payment (PRICE) structure. It builds the schedule where the total monthly payment stays the same.
calculate_amortizationData comparison
The agent compares the two resulting schedules. It highlights the differences in interest and total cost.

How this task behaves
- 01
Does the AI guess the math?
No. The AI uses the calculate_amortization tool to perform deterministic math, so the results are precise.
- 02
Can the AI change my bank's interest rates?
No. The AI only performs calculations based on the numbers you provide.
- 03
Can it create a PDF of the schedule?
No. The tool provides the data and the schedule in text or table format within your chat.
- 04
Can I use this with Claude?
Yes, as long as you are using an MCP-compatible client like Claude Desktop.
- 05
Does it handle custom loan types?
It handles SAC and PRICE structures. If a structure isn't supported by the tool, the AI cannot calculate it.
