Frequently asked questions
What is an annuity?
A series of equal payments made at regular intervals — this calculator computes the future value of contributing to one, such as a recurring investment or savings plan.
What's the difference between annuity-due and ordinary annuity?
Annuity-due assumes each payment is made at the start of the period (getting one extra period of compounding); ordinary annuity assumes payment at the end. This calculator uses the annuity-due convention, standard for Indian SIP-style calculators.
How is this different from the SIP Calculator?
It's the same underlying formula — "annuity" and "SIP" both describe a series of regular contributions growing at compound interest.
