How this service works
Zach Riehn's lab: an about-me and portfolio, a news desk, The Atelier for AI experiments, Launch Lab for XRP research, and Fracture for games.
Output
Returns a JSON object with the final_balance (total value at end of period), contributed (total amount deposited including principal and monthly additions), and growth (interest earned), plus a disclaimer note that it is illustrative and not financial advice.
Example use cases
Retirement savings projection
“I'm starting with $10,000 in retirement savings and plan to add $300 a month at a 6% annual interest rate — how much will I have after 30 years with monthly compounding?”
College fund growth estimate
“If I open a college fund with $2,000 today and deposit $100 a month at 5% annual interest, what's the projected balance after 18 years?”
Short-term savings goal
“I have $500 saved up and I'm putting in $50 a month into an account earning 4.5% per year. What will I end up with after 3 years, compounding monthly?”

Use this endpoint when you need a quick, deterministic compound interest calculation with support for monthly contributions. It is well-suited for personal finance projections, savings goal modeling, or educational illustrations. Prefer this over a generic calculator when you need a structured JSON response for downstream processing in an agent workflow.
