How it works

  • Enter your numbers — use the sliders or type directly. Everything recalculates live.
  • Bank-grade formulas — EMI uses the reducing-balance method, SIP compounds monthly, FD/RD compound quarterly, exactly like Indian banks.
  • Fully private — there is no server. Your numbers are processed in your own browser and never sent anywhere.
