This solver can calculate monthly or yearly, fixed payments you will receive over a period of time, for a deposited amount
(present value of annuity) and problems in which you deposit money into an account in
order to withdraw the money in the future (future value of annuity).
The calculator can solve annuity problems for any unknown variable (interest rate, time, initial deposit
or regular deposits). It will also generate a detailed explanation of how the calculations were done.

examples
A deposit of $\color{blue}{\$120}$ is placed into an account at the $\color{blue}{\text{beginning}}$ of every $\color{blue}{\text{month}}$ for $\color{blue}{8 \, \text{years}}$.
The bank pays $\color{blue}{7\,\%}$ annual interest rate, compounded monthly, and paid at the $\color{blue}{\text{end of the month}}$.
How much is in the account after the last deposit?
How much money must you deposit now at $\color{blue}{4\,\%}$ interest in order to be able to withdraw $\color{blue}{\$800}$ at the $\color{blue}{\text{end}}$ of each $\color{blue}{\text{year}}$
for $\color{blue}{\text{three}}$ years?
Suppose you deposited $\color{blue}{\$50 000}$ into a bank account at $\color{blue}{6\%}$ annual interest rate. How many $\color{blue}{\text{months}}$ you can
withdraw $\color{blue}{\$300}$ at the $\color{blue}{\text{end of each month.}}$
If you need $\color{blue}{\$\,30 000}$ in $\color{blue}{\text{10 years}}$ and you get an interest rate of $\color{blue}{5 \%}$, how much must you invest each of the
next $\color{blue}{\text{10 years?}}$
