How is FD interest calculated?
Maturity = P × (1 + r/k)^(k × t), where k is how many times a year interest compounds. Most Indian banks compound fixed deposits quarterly, which is the default here.
Is FD interest taxable?
In India, yes: FD interest is added to your income and taxed at your slab rate, and banks deduct TDS above a threshold. This calculator shows pre-tax returns.
