How accurate is this balloon loan?
Every formula on this site comes from an established, published source for its field — standard references in mathematics, finance, health, and engineering, not invented in-house. The math is implemented as a pure TypeScript function and tested against published reference values before going live. See the Methodology page for the full sourcing process.
Results are mathematically correct for the inputs provided. They are estimates only— real-world outcomes depend on factors specific to your situation, such as fees, taxes, timing, local rules, and assumptions that can change after the calculation date.
