🧭 Step-by-Step Usage Guide
🚘 Step 1: Select Car Type
The first option in the calculator is Car Type.
You will see multiple car categories such as:
✔ How it works:
Each car type has a fixed base rental price per day. When you select a car, the calculator automatically uses that price as the base rate.
👉 Example:
If you select SUV, the system will use $90/day as the base cost.
⏱ Step 2: Choose Rental Mode
Next, you must select the Rental Mode:
Per Day
Per Hour (÷24 rate)
✔ Explanation:
If you choose Per Day, full daily charges are applied.
If you choose Per Hour, the system divides the daily rate by 24 to calculate hourly cost.
👉 Example:
SUV = $90/day
Hourly rate = $90 ÷ 24 = $3.75/hour
This gives users flexibility depending on their rental needs.
📅 Step 3: Enter Duration (Days or Hours)
In this field, you must enter how long you want to rent the car.
If you selected Per Day, enter number of days.
If you selected Per Hour, enter number of hours.
✔ Example:
3 days rental → enter3
10 hours rental → enter10
The system will multiply this value with the selected rate.
🛣 Step 4: Enter Distance (KM)
This field calculates fuel or travel cost based on distance.
✔ How it works:
The system multiplies:
Distance (KM) × Fuel Cost per KM
👉 Example:
Distance = 120 KM
Fuel rate = $0.50 per KM
Fuel cost = 120 × 0.50 = $60
This ensures accurate travel expense calculation.
⛽ Step 5: Fuel Cost per KM
Here you define how much fuel costs per kilometer.
This value depends on:
Fuel prices in your area
Vehicle type efficiency
Trip conditions
✔ Example values:
$0.30 (low consumption car)
$0.50 (average)
$0.80 (luxury SUV or long travel)
🧾 Step 6: Add Extra Services
The calculator also supports additional services, such as:
No Extra Services
Driver ($20/day)
Insurance ($30/day)
Driver + Insurance ($50/day)
✔ How it works:
These charges are multiplied by the number of rental days or hours.
👉 Example:
If you choose Driver + Insurance:
Extra cost = $50 × duration
This allows users to customize their rental package.
🎟 Step 7: Enter Coupon Code (Optional)
You can apply discount coupons to reduce the final price.
✔ Available coupons:
-
DESH10→ 10% discount
-
DESH20→ 20% discount
✔ Example:
If total bill is $200 and you apply:
DESH10 → save $20
DESH20 → save $40
If no coupon is entered, no discount is applied.
🧮 Step 8: Click “Calculate Invoice”
After filling all fields, click:
👉 Calculate Invoice
The system will instantly display:
Base Cost
Fuel Cost
Extra Services Cost
Subtotal
Discount
Final Total Payable
✔ Example Output:
You will see a clean breakdown like:
Base Cost: $180.00
Fuel Cost: $60.00
Extra Cost: $40.00
Subtotal: $280.00
Discount: -$28.00
Total Payable: $252.00
This makes pricing fully transparent.
