Project where steady monthly growth takes your revenue: month by month, the final month and the total for the period.

## What it calculates

A growth forecast compounds: each month grows on top of the last, so small monthly rates add up over a year. This calculator applies one growth rate to today's revenue. It is a plan to test against, not a prediction.

## Formula

```
Month n revenue = Base × (1 + growth)^n
Total = sum of months 1 to n
Growth vs today = Final month ÷ base − 1
```

## Worked example

Inputs:
- Revenue this month: USD 40,000
- Monthly growth: 5%
- Months ahead: 12

Results:
- Revenue in the final month: USD 71,834
- Total over the period: USD 668,519
- Growth vs today: 79.6%

## What changes the result

Monthly growth at five values; every other input as in the example.

| Monthly growth | Revenue in the final month | Total over the period |
| --- | --- | --- |
| 2.5% | USD 53,796 | USD 565,618 |
| 3.8% | USD 62,579 | USD 616,762 |
| 5% (example) | USD 71,834 | USD 668,519 |
| 6.3% | USD 83,264 | USD 730,000 |
| 7.5% | USD 95,271 | USD 792,220 |

## How to read the result

Use the growth rate from your own recent months, not a hoped-for one.
Check the plan against stock, cash and ad budget: each needs to grow with revenue.

## Questions

**How do I forecast ecommerce sales?**
Start from current monthly revenue and a growth rate from your recent history, and compound it month by month.

**What growth rate should I use?**
Your own average monthly growth over the last few months.

**Why does 5% a month become more than 60% a year?**
Because growth compounds. 1.05 to the power of 12 is about 1.8.

**Do you store what I enter?**
No. The calculation runs in your browser and nothing is sent to Analify.
