Game calculator
The calculator helps an organizer see whether a game will make a profit. Choose a sport, enter the courts, rental time, participants and participation fee, and you will immediately see income, expenses and profit.
What it is
The calculator works out the economics of one game: how much the participants bring in, how much the court rental costs, and what is left at the end.
- Calculates in your browser. The result updates with every change, and the page does not reload.
How to open it
Open the “Games & Partners” section
On the home page, click the “Games & Partners” tile.
Open the calculator
In the section, click the “Game calculator” tile.
Fill in the form
Pickleball is selected by default. Change the sport and the other fields: the result appears on the right, and on a phone it is pinned to the top of the screen.
Sports
The calculator supports three sports: Pickleball, Padel and Tennis. You choose the sport in the “Game” card.
When you change the sport, the calculator fills in its own starting values: rental time, court price, participation fee, number of courts, number of participants and game length. The game format, turnout and planning mode stay as they are.
If you clear the sport with the “Clear” button, the values you entered stay, and the result is hidden until you choose a sport again.
Form cards
The form is split into three cards.
Game
- Sport — Pickleball, Padel or Tennis.
- Game format — two tiles: “Singles: 2 per court” or “Doubles: 4 per court”.
- Game length — one of three tiles.
- Pickleball: “To 11”, “To 15”, “To 21” — about 15, 20 and 30 minutes.
- Padel and Tennis: “Tie-break” — about 10 minutes, played to 7 points, a super tie-break goes to 10; “To 4 games” — about 15 minutes; “To 6 games” — about 25 minutes.
Game length does not affect income or expenses. It is used only in the “Per participant” block.
Courts
- Number of courts — how many courts you rent.
- Rental time, hours — for example, 1.5 means one and a half hours. Enter it in steps of 0.05 hours. The ”−” and ”+” buttons change the value by 0.5 hours.
- Court rental per hour — the price of one court for one hour.
Participants
- Participants — how many people will play and pay.
- Plan for no-shows — a checkbox. It is off by default, so all participants are counted as coming. When it is on, the field is called “Invited”, the “Expected turnout” field appears (starts at 75%), and the result is calculated for the expected participants.
- Participation fee — how much one participant pays.
How to enter numbers
- The ”−” and ”+” buttons change the value by one step. Sliders are available for courts, rental time, participants and turnout.
- You can type numbers on the keyboard. Regular digits 0–9, Arabic-Indic digits (٠–٩) and Persian digits (۰–۹) are accepted.
- Money and counts are whole numbers without spaces:
1000, not1 000. - Percentages allow up to two decimal places, with a dot or a comma:
12,5or12.5. You do not need to type the ”%” sign. - The result is always shown with regular digits 0–9.
Starting values
Starting values depend on the sport and on the site currency. They are guidelines, not market prices: court prices in your city may be different.
| Currency | Pickleball: court per hour | Pickleball: fee | Padel and Tennis: court per hour | Padel and Tennis: fee |
|---|---|---|---|---|
| USD | 40 | 20 | 80 | 40 |
| EUR | 30 | 15 | 60 | 30 |
| PHP | 300 | 150 | 800 | 300 |
| RUB | 3000 | 1500 | 6000 | 3000 |
For other currencies, the USD values are used without converting the exchange rate.
| Parameter | Pickleball | Padel and Tennis |
|---|---|---|
| Number of courts | 2 | 3 |
| Participants | 8 | 12 |
| Rental time | 2 hours | 2 hours |
| Game format | Doubles: 4 per court | Doubles: 4 per court |
| Game length | To 11 (≈ 15 min) | To 4 games (≈ 15 min) |
| Turnout (when the checkbox is on) | 75% | 75% |
What the result shows
The result is shown on the right of the form. On a phone, the profit block is pinned to the top of the screen, so the number stays visible while you change the fields.
- Profit — in large type. It is income minus expenses. Profit can be negative: that is a loss.
- Income — money from participation fees: number of participants multiplied by the participation fee.
- Expenses — the rental of all courts for the whole time: number of courts × hours × court price per hour.
- Profit share — the part of income that remains as profit. If there is no income, “No income” is shown.
If there are more participants than places on the courts at the same time, they play in turns. The result then shows the line “Participants play in turns: N play at a time”. All participants pay in this case, so income is counted for all of them.
Per participant
- Games played — an approximate number of games, for example ”≈ 8”.
- Rest between games — how many minutes a participant rests between games on average. If there is no rest, “none” is shown.
What could change
This block is collapsed. Open it to see:
- To cover costs — how many participants are needed at the current participation fee, and the minimum participation fee needed at the current number of participants.
- Recommendations — if the participation fee is below the minimum, the calculator suggests raising it to the required level. The recommendation appears only when the fee does not cover costs.
If you open this block, it stays open even when a field is temporarily filled in incorrectly.
Input errors
- If a field is filled in incorrectly, the reason and the allowed range appear under it, for example “Enter a value from 0 to 100”.
- Instead of the result on the right, you see “Fix the highlighted fields to see the result”.
- If no sport is chosen, the right side says “Pick a sport to see the result”, and the sport field shows “Choose a sport”.
Calculation example
Pickleball, currency USD, starting values: 2 courts, 2 hours, 8 participants, doubles, “To 11” (about 15 minutes), the checkbox is off. Fee 20 USD, court 40 USD per hour.
| Indicator | Value |
|---|---|
| Income | 160 USD |
| Expenses | 160 USD |
| Profit | 0 USD |
| Profit share | 0% |
| Games played | ≈ 8 |
| Rest between games | none |
Income: 8 participants × 20 USD = 160 USD. Expenses: 2 courts × 2 hours × 40 USD = 160 USD. Profit: 160 − 160 = 0 USD.
The “What could change” block shows:
| Indicator | Value |
|---|---|
| Participants needed | 8 |
| Minimum participation fee | 20 USD |
What the calculator does not include
The calculator counts only court rental and participation fees. It does not include:
- taxes;
- discounts on the fee;
- the platform commission;
- sponsor support;
- equipment: balls, nets and everything else needed for a game;
- referee fees and other costs.
A game is considered held with any number of participants, starting from one. If there are no participants, the calculator says the game is cancelled.
The rule “all participants pay” with turns holds only while there are no more than 100 invited people per court (a limit of the calculation core). Typical games do not reach this limit.
Frequently asked questions
Why is the profit zero at the start?
The income from the starting values (8 × 20 USD) equals the court rental cost (2 × 2 × 40 USD). To make a profit, raise the participation fee or increase the number of participants.
Why is the Recommendations block not shown?
The participation fee recommendation appears only when the fee does not cover costs. If the income is not lower than the expenses, the block is hidden. The minimum fee needed to break even is shown in the “To cover costs” block.
Why is the number of games shown with ”≈” and sometimes fractional?
The number of games is rounded. If there are ten games or more, it is rounded to a whole number. If there are fewer than ten, it is rounded to the nearest half, so you may see something like ”≈ 7.5”.
