Quick answer

Compare ending revenue with starting revenue to measure the percentage change. Use equal reporting periods and a consistent definition of sales.

RESULT
Calculated output
0

25.00% is the example result. A percentage growth rate depends on the starting base. A small starting amount can produce a large rate even when the absolute change is modest.

Result = (([Ending revenue] − [Starting revenue]) ÷ ([Starting revenue])) × 100
Purpose

Compare ending revenue with starting revenue to measure the percentage change. Use equal reporting periods and a consistent definition of sales.

Comparing financial amounts on a defined basis

A percentage growth rate depends on the starting base. A small starting amount can produce a large rate even when the absolute change is modest. A financial model is useful when its cash amounts, rate convention and time horizon describe the same case. Interest, return and purchasing power are different outputs. A projection should remain separate from an observed or audited balance.

What the model includes

Result = (([Ending revenue] − [Starting revenue]) ÷ ([Starting revenue])) × 100 Check whether a rate is annual, monthly, simple or compounded. Enter fees only where the form represents them and identify contractual charges that remain outside the estimate. A monthly payment alone does not establish affordability or total ownership cost. Use the result to prepare the next question about terms or assumptions. Tax treatment, lender conditions and valuation evidence require the relevant source documents; they cannot be recovered from a few numeric inputs.

Example with the supplied inputs

Starting revenue: 100000; Ending revenue: 125000. Result: 25.00%. The values are illustrative.

Compare one changed input

Starting revenue changes from 100000 to 110000. The result becomes 13.64%. All other inputs remain fixed.

Calculation rule

Formula

Result = (([Ending revenue] − [Starting revenue]) ÷ ([Starting revenue])) × 100

Inputs and output

Example inputs and entry conventions
Input Example value Entry convention
Starting revenue 100000 Use starting revenue on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate.
Ending revenue 125000 Use ending revenue on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate.

Output: 25.00% is the example result. A percentage growth rate depends on the starting base. A small starting amount can produce a large rate even when the absolute change is modest. Use the formula to distinguish a cash amount, count, percentage or ratio.

How to use the page

STEP 01

Collect the inputs

Gather Starting revenue, Ending revenue. Use one period and the units shown in the form.

STEP 02

Run the calculation

Enter the values and select the action. The calculation rule above explains how the inputs produce the result.

STEP 03

Compare a scenario

Change Starting revenue on its own, keeping the other inputs fixed. Read both results before changing another assumption.

Worked example

With the example inputs listed above, the result is 25.00%.

Change Starting revenue from 100000 to 110000 while keeping every other value fixed. The result becomes 13.64%. This comparison isolates that input; it does not forecast how other variables will respond.

Check the stated formula, units and limits before using the result in a decision.

Calculation and source notes

Keep the displayed formula, input units and model scope with the result. Corrections or questions can be sent through the request section on this page.
