About

Galvin Mendonca is a finance researcher and the sole creator of FinanceUp. He independently researches tax systems, retirement accounts, mortgages, and investment vehicles across 10 countries to provide accurate, localized financial planning tools.

Every calculator, comparison guide, blog post, and glossary definition on FinanceUp is written and maintained by Galvin to ensure accuracy and consistency. His work makes complex global financial regulations accessible to individuals, expats, and small business owners navigating multi-country financial planning.

Galvin built FinanceUp to solve a personal frustration: the lack of reliable, country-specific financial calculators that handle real-world tax rules, contribution limits, and regulatory nuances. Rather than settling for generic tools, he engineered a system that maps standard mathematical formulas to localized rule databases—delivering exact estimates for US 401(k) matching, UK ISA limits, Australian superannuation, Canadian RRSP/TFSA rules, and more.

Research Focus & Methodology

FinanceUp is built entirely on hands-on manual research, regulatory documentation analysis, and simulation testing. Without relying on generic financial templates, Galvin maps out local tax brackets, retirement rules, and mortgage structures for each supported country.

Key areas of research and simulation verification include:

• Global Tax Systems: Manually parsing and verifying progressive tax brackets, standard deductions, and regional tax rules (e.g., US federal vs. Swiss cantonal taxes).
• Retirement & Savings Rules: Tracking contribution limits, employer matches, and tax-exempt statuses for accounts like the US 401(k), UK ISA, Canadian TFSA/RRSP, and Australian Superannuation.
• Mortgage & Loan Math: Calculating amortization tables, comparing fixed vs. variable rates, and modeling how offset accounts reduce interest costs under local rules.
• Investment Strategy: Modeling compounding returns, index fund growth, and tax drag across different brokerage accounts.
• Data Verification: Utilizing mathematical modeling and programmatic verification to cross-check calculators against official government tables and tax simulators.
