Union Bank FD calculator
Use this free Union Bank FD calculator to work out the maturity amount and interest on a Union Bank of India fixed deposit. Union Bank's official FD interest rates and senior citizen rates are preloaded, with monthly interest, premature withdrawal rules and post-tax returns.
What your FD actually earns
Five calculation modes on one engine — cumulative growth, monthly payout, goal sizing, laddering and loan-against-FD. Every mode shows the post-tax and inflation-adjusted figure beside the headline number, because the headline rate is rarely the one you keep.

The essentials
Union Bank FD returns: monthly interest, senior citizen rates and comparison
Monthly interest on a Union Bank FD
With a monthly payout Union Bank FD at the 1-year rate of 6.20%, interest is about ₹517 a month on ₹1 lakh, ₹2,583 on ₹5 lakh and ₹5,167 on ₹10 lakh, before tax. Banks usually pay monthly interest at a slightly discounted rate, so treat these as close estimates. Switch the calculator to Monthly income mode to see the post-tax figure. Payout deposits earn less in total than cumulative ones, because the interest is paid out instead of compounding.
Union Bank FD for senior citizens
0.50% above the general rate. Tick "Senior citizen" in the calculator and it loads the senior rate for the tenure you pick. For example, ₹10 lakh for 5 years at 6.50% grows to about ₹13.80 lakh. Senior citizens under the old tax regime can also claim the 80TTB deduction on up to ₹50,000 of interest a year, and can submit Form 15H to avoid TDS if their total income is below the taxable limit.
