Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

Frequently Asked Questions

When does health start improving?

Carbon monoxide clears within a day, circulation improves over two to twelve weeks, and lung function gains up to 10% within nine months.

Does the financial figure help?

Considerably, in behavioural studies. Naming a specific purchase for the saved amount is more effective than an abstract total.
