About this calculator
You can change any value. After changing a number, either press enter or just click outside of the text box to recalculate. The other values will be updated automatically.
Values can be locked simply by selecting the field you would like to lock on the right-hand side or underneath the calculator on desktop and mobile respectively. Locking a particular field will ensure that it does not change as you adjust the other values.
Click the menu button to reset to default settings or save/load your current values.
