Enter up to 10 capacitor values (with units like pF, nF, μF, mF, or F) into the Parallel Capacitor Calculator to find the total capacitance of your parallel circuit. Add as many capacitors as you need — the tool sums all non-zero values and displays the result in the most readable unit automatically.

The total capacitance of capacitors connected in parallel is simply the sum of all individual capacitances: C_Total = C1 + C2 + C3 + ... + Cn. This means adding capacitors in parallel always increases the total capacitance beyond the largest single capacitor value.
In a parallel configuration, all capacitors share the same voltage but each stores additional charge independently. The circuit effectively has a larger combined plate area, so the total charge storage capacity — and therefore total capacitance — is the direct sum of all individual values.
Capacitors in parallel add their capacitances directly (C_Total = C1 + C2 + ...), resulting in a total larger than any individual capacitor. Capacitors in series combine as reciprocals (1/C_Total = 1/C1 + 1/C2 + ...), giving a total smaller than the smallest capacitor. This is the opposite behavior to resistors.
Enter the value and unit (pF, nF, μF, mF, or F) for each capacitor you want to include. Leave any unused fields blank. The calculator sums all entered values and displays the total capacitance in all common units simultaneously.
Yes. Each capacitor entry has its own unit selector, so you can freely mix picofarads, nanofarads, microfarads, millifarads, and farads. The calculator converts everything to a common base unit (farads) before summing, then presents the result in all units.
When capacitors are wired in parallel, both terminals of every capacitor are connected to the same two nodes in the circuit. This means each capacitor sees the exact same voltage across its plates, but each independently stores charge proportional to its own capacitance value.
This calculator supports up to 10 capacitors at once. If you have more than 10, calculate the first 10 to get a subtotal, then use that subtotal as one of the inputs in a second calculation along with your remaining capacitors.
Parallel capacitor banks are used in power supply filtering to reduce ripple voltage, in audio crossover networks, in RF tuning circuits to achieve specific capacitance values not available in a single component, and in bypass/decoupling applications where multiple smaller capacitors are placed in parallel to cover a wider frequency range.
