How to Use This Calculator

Enter the cost of your microcontroller board and the number of shields or expansion modules.
Set average shield and sensor costs along with total passive component count and cost.
Include PCB and 3D-printed enclosure costs if applicable.
Review the electronics subtotal, project subtotal, estimated shipping, and grand total with contingency.

How the result changes with Shields / Modules

Microcontroller Board ($): Cost of main board (Arduino Uno ~$25, Nano ~$12, ESP32 ~$8, Mega ~$40).
Shields / Modules: Number of add-on shields or breakout modules (motor driver, relay, display, etc.).
Avg Shield Cost ($): Average cost per shield/module.
Sensor Count: Number of sensors (temperature, motion, light, distance, etc.).
Avg Sensor Cost ($): Average cost per sensor.
Passive Components: Total resistors, capacitors, LEDs, diodes, transistors, wire, headers.
PCB / Breadboard ($): Cost for PCB fabrication or breadboard/perfboard.
Enclosure ($): Project enclosure (3D printed, off-the-shelf, or custom).

Electronics Subtotal ($): Total cost of electronic components only.
Project Subtotal ($): All costs before shipping (includes PCB, enclosure, power supply).
Est. Shipping ($): Estimated shipping cost.
Grand Total ($): Total project cost including shipping.
Contingency (10%) ($): Budget buffer for mistakes and replacement parts.
Total + Contingency ($): Grand total with 10% contingency for a realistic budget.
Shields Total ($): Total shield/module cost.
Sensors Total ($): Total sensor cost.

Microcontroller Board ($) = 25, Shields / Modules = 2, Avg Shield Cost ($) = 8, Sensor Count = 3 = 8 input(s) provided
Calculate Electronics Subtotal
Electronics Subtotal = boardCost + shieldTotal + sensorTotal + passiveTotal + connectorCost
66.5 = $66.5
Calculate Project Subtotal
Project Subtotal = componentSubtotal + pcbCost + enclosureCost + powerSupplyCost
96.5 = $96.5
Calculate Est. Shipping
7.72 = $7.72
Calculate Grand Total
Grand Total = projectSubtotal + shippingEstimate
104.22 = $104.22
