About this calculator
Doubling price rarely halves sales. Model the elasticity you actually observe, then compare total contribution across price points before you discount.
Worked example
Using the values the calculator loads with:
Inputs
- Current price: 49 $
- Units sold per month: 220
- Proposed price: 79 $
- Price elasticity (units drop per 1% price rise): 0.7
- Variable cost per sale: 4 $
Results
- Revenue at proposed price: $9,931.43
- Revenue at current price: $10,780.00
- Revenue change: -$848.57
- Expected units at new price: 125.71
- Contribution at new price: $9,428.57
- Contribution at current price: $9,900.00
What each field means
Inputs
- Current price ($)
- The current price used in the calculation, measured in $. Starts at 49 $ so you have a working example on load.
- Units sold per month
- The units sold per month used in the calculation. Starts at 220 so you have a working example on load.
- Proposed price ($)
- The proposed price used in the calculation, measured in $. Starts at 79 $ so you have a working example on load.
- Price elasticity (units drop per 1% price rise)
- The price elasticity (units drop per 1% price rise) used in the calculation. Starts at 0.7 so you have a working example on load. Accepted range: 0–4.
- Variable cost per sale ($)
- The variable cost per sale used in the calculation, measured in $. Starts at 4 $ so you have a working example on load.

FAQ
How does the digital product pricing calculator work?
Doubling price rarely halves sales. Model the elasticity you actually observe, then compare total contribution across price points before you discount. The underlying maths is: Revenue = Price × Units, with units adjusted by elasticity for each price change.
What do I need to enter?
5 values: current price, units sold per month, proposed price, price elasticity (units drop per 1% price rise), and variable cost per sale. Each field starts with a sensible default, so you can change one number at a time and watch the result move.
What does the revenue at proposed price result mean?
It is returned as a money amount in US dollars and updates live as you edit the inputs, so you can compare two or three versions of a scenario in a few seconds.
Is this calculator free, and do I need an account?
Yes, it's free, and no account is required. Nothing you type is stored on our servers — the maths runs entirely in your browser.
How accurate is the result?
It applies the standard formula exactly, so the arithmetic is precise. Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
Who is this tool for?
It's built for anyone comparing money scenarios before committing — budgeting a payment, sanity-checking a quote, or seeing what a change in rate or term actually costs.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
