> The future value of annuity calculator works out what a series of regular payments will be worth in the future – with any payment frequency, compounding, ordinary or due timing and growing payments.

## Inputs

- Payment per period
- Annual interest rate (%)
- Number of years (years, months)
- Payment frequency
- Compounding frequency
- Payments made at
- Growth of payments per year (%)

## Results

- Number of payments
- Future value
- Total payments
- Interest earned

## Formula

```
FV = P × ((1 + i)^n − 1) ÷ i × (1 + i × timing)
Growing: FV = P × ((1 + i)^n − (1 + g)^n) ÷ (i − g) × (1 + i × timing)
```

## Explanation

The future value of an annuity answers "what will my regular savings grow to?". An annuity due is worth (1 + i) times an ordinary annuity because every payment earns one more period of interest.

### How to use the Future Value of Annuity Calculator

- **Payment per period**
- **Annual interest rate**
- **Number of years**
- **Payment frequency**
- **Compounding frequency**
- **Payments made at**
- **Growth of payments per year**

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Enter the payment, interest rate, number of years, payment frequency, compounding, timing and payment growth.

### Tips

- Start early – time does more of the work than the amount you save.
- Take the full employer match if your plan offers one.
- Plan with a cautious return (4–6% after inflation) and check again every year.
- Know the contribution limits and required minimum distribution rules for your accounts.

### Common mistakes to avoid

- Ignoring inflation when setting a retirement target.
- Underestimating how long retirement can last.
- Withdrawing early and paying penalties and taxes.

### What each result means

- **Number of payments** = round([Number of years]×[Payment frequency])
- **Future value** = gfv([Rate per payment period], [Number of payments], [Payment per period], [Payment growth per period], [Payments made at])
- **Interest earned** = [Future value] - [Total payments]

### Example values

How the main result changes when **Payment per period** changes and everything else stays at the example values above:

## Worked example

Inputs — Payment per period: $500; Annual interest rate: 6 %; Number of years: 20 years; Payment frequency: Monthly; Compounding frequency: Monthly; Payments made at: End of each period; Growth of payments per year: 0 %.

Results — Number of payments = 240; **Future value = $231,020.45**; Total payments = $120,000.00; Interest earned = $111,020.45.

## FAQ

**What is the future value of an annuity?**

Payments at the start of each period earn one extra period of interest.

**What is a growing annuity?**
Payments that rise by a fixed percentage each period.

**What formula does the Future Value of Annuity Calculator use?**
