About CashOutline

CashOutline builds free, browser-side personal finance calculators for individuals in Southeast Asia and the US who want to make better decisions about savings, debt, and insurance — without sharing personal data with any server. We believe that clear, accurate financial math should be available to everyone, regardless of where they bank or what language they speak. Our tools are designed to give you honest answers in seconds, with no account and no strings attached.

What We Build

Our growing tool suite currently covers interest rate conversion — helping you compare APR and APY across different compounding periods — and insurance premium estimation for budgeting coverage costs before you commit to a policy. We are actively developing tools for compound interest projection, structured debt payoff planning, retirement savings modeling, and net worth tracking. Every calculator is built around real-world financial products and is designed to work equally well whether you are comparing fixed-deposit rates in Bangkok, evaluating a personal loan in Manila, or mapping out retirement contributions in the US.

Our Approach

• All calculations run locally in your browser — nothing is sent to any server. Your numbers stay on your device, every time.
• No registration, no paywall, no personal data collected. Every tool is free to use with no account required and no information harvested in the background.
• Real examples from Thailand, Vietnam, the Philippines, and Indonesia are included in every tool, so the inputs and outputs reflect the financial products and conventions you actually encounter.

Who Is This For

CashOutline is built for anyone who wants a clearer picture of their finances before making a commitment. If you are a saver comparing deposit accounts and want to understand what a difference in compounding frequency actually means for your balance, these tools are for you. If you are a borrower evaluating the true cost of a loan beyond the advertised rate, we give you the numbers without the sales pitch. If you are an individual planning insurance coverage and need a private, pressure-free estimate before speaking to an agent, our calculators give you a grounded starting point. And if you are an expat navigating Southeast Asian financial products — where rate conventions, tax rules, and coverage structures often differ from what you are used to — CashOutline provides the transparency you need to make decisions with confidence.
