Assumptions and limits

The result is derived only from the 2 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.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Does the leap day affect this?

Yes - in a leap year there is one more day to divide by, which shifts the elapsed percentage slightly.

Is the working day figure exact?

No, it is a pro-rata estimate. Exact counts depend on which weekdays the remaining period contains and on public holidays.
