This is a javascript based AVR fuse calculator. You must have javascript enabled to use this. There are lots of places with mouse-over text (alt-text) to provide some help.
You can select a AVR chip from the dropdown menu at the top of the page. If a chip is marked as 'similar', it means that chip has identical fuses and preset collections as the currently selected chip
When you select another chip, the fuse settings from the current chip will be applied to the new chip (even if the chips are not similar).
In Appstore there is a new version of Avrfusescalc (2.1), for macOS. I have improved cooperation with 'small' Attiny, i.e. Attiny10, 9 etc. Version 2.0 AVRFusesCalc allowed to sets fusebits in these microcontrollers, but not allowed to reset them to factory values.
Presets are known defined settings available for the AVR chip you've selected. Changing a preset setting will automatically apply the changes to the fuse bits.
Manually manipulating the fuse bits will also cause the calculator to find the preset that matches the fuse bit setting.

Written on 14 January 2016. Posted in Applications “AVRFusesCalc” is an application through which we can easily set the fuse bits and lock bits in the microcontrollers ATmega and ATtiny. “AVRFusesCalc” is an application through which we can easily set the fuse bits and lock bits in the microcontrollers ATmega and ATtiny. To be able to set fuse bits should be installed on the avrdude and AVR-GCC package. People using Arduino can use 'avrdude' which comes with this application.
Be extra careful about anything with a star *, the star * means the setting is related to ISP programming. If ISP programming becomes disabled (by disabling SPI programming, disabling the reset pin, or enabling debugWIRE), you will require special equipment (HV programmer, parallel programmer, or something with debugWIRE) to change them back.
The AVRDUDE commands may be used as arguments with AVRDUDE to program the fuses.

Some bits that are undefined may not be verified as correct, but as they are undefined, that's usually not a problem.
Make sure you don't mess up your chip by disabling the programming features or locking the chip completely.
