About rentvsbuy.in
The story behind the calculators.
rentvsbuy.in started with a simple question: should I rent or buy a home in India? Most online calculators gave vague answers with hidden assumptions. We built one that shows every number, every assumption, and lets you adjust everything.
Since then, we have added calculators for home loans, SIPs, EMIs, income tax, solar panels, and more - all designed specifically for Indian salaries, tax slabs, and market conditions. No generic formulas with a rupee sign pasted on.
Every calculator runs entirely in your browser. Your financial data stays on your device unless you explicitly choose to save a run to your account.
