How this is calculated
Formula: Maturity = P × (1 + r/4)4t for a cumulative FD compounded quarterly, where P is the principal, r the annual rate and t the tenure in years.
FD interest is fully taxable at your slab and banks deduct TDS above a threshold. For long horizons, tax-free PPF or equity ELSS can be more efficient.

Frequently asked questions
How is FD maturity calculated?
For a cumulative FD, maturity = P × (1 + r/n)^(n×t), where P is the principal, r the annual rate, n the compounding frequency (banks usually compound quarterly, so n = 4) and t the tenure in years.
Is FD interest taxable?
Yes — FD interest is fully taxable at your income-tax slab and banks deduct TDS above a threshold. Tax-free options like PPF, or equity ELSS with LTCG treatment, can be more tax-efficient for long horizons.
Quarterly vs annual compounding — does it matter?
Quarterly compounding (the Indian bank standard) gives a slightly higher effective yield than annual, because interest is added to the principal four times a year and itself earns interest.
