Finanease – React Financial planning & Smart Math Workflow Calculator Suite

Description

Live View

Finanease is a complete React toolkit for building modern financial planning experiences. Instead of coding every calculator from scratch, you get a ready-made suite covering loans, investments, retirement, tax and everyday money decisions, all presented through clean dashboards and interactive charts.

Each tool is built as a self-contained component, so developers can drop a single calculator into an existing app or combine the whole collection into a full financial platform. Because every calculation runs in the browser, results appear instantly, work offline, and keep user data private with no server round-trip.

What you can build with it

• Loan and debt tools, including EMI, car loan, prepayment, home affordability, debt payoff, consolidation, mortgage refinance and buy-versus-rent comparisons.
• Investment and wealth tools, including growth planning, ROI, dividends, stock options, rebalancing, annuities and business valuation.
• Retirement and long-term planning, including retirement savings, FIRE planning, scenario simulation, emergency funds, education savings and net worth tracking.
• Tax and salary planning, including multi-country income tax, tax-saving optimisation, capital gains, tax brackets, take-home pay and related estimators.
• Analysis and business insight, including inflation impact, savings rate, freelance income, lifestyle costs and event budgeting.

Why developers like this stack

Finanease is built with React 19, TypeScript 5, Tailwind CSS 4 and Recharts, with Vite for fast development and builds. Its mathematical core uses structured JSON-in and JSON-out models, which makes each calculator easy to test, extend and connect to AI-assisted workflows. Results can be exported as PDF or CSV, and screenshots can be captured directly from the interface.

The interface is responsive, supports dark mode, and adapts currency symbols and number formatting for different regions. Whether you are adding one smart calculator to a SaaS dashboard or launching a dedicated financial planning product, Finanease gives you a polished, extensible starting point without reinventing the maths.
