dhanKit is a free collection of 18 financial calculators designed specifically for Indian retail investors and salaried professionals. The tools cover the most common financial planning scenarios — SIP, EMI, PPF, FD, NPS, EPF, CAGR, recurring deposits, gratuity, and retirement planning.
More specialized calculators include a cost-of-delay visualizer, a goal planner, a mutual fund returns calculator, and a debt payoff strategist that compares avalanche vs. snowball repayment strategies.
Every calculator provides instant, real-time results as inputs change — no submit buttons, no waiting. Results are displayed with clear visual breakdowns using donut charts for invested-vs-returns splits, year-by-year breakdown tables, and prominent result cards.
All monetary values use Indian number formatting (lakhs and crores), and calculations follow the standard Indian financial formulas for each instrument. Users can share calculator results via URL parameters, making it easy to send a specific scenario to someone.
The site is built as a progressive web app on Next.js with React and Tailwind CSS. Calculator logic is cleanly separated into individual modules with comprehensive test coverage via Jest.
An educational blog section with 20+ articles on personal finance topics complements the tools, and Vercel Analytics tracks usage patterns to guide which calculators to build next.
