About Autopay Total Calculator

Automatic mandates are convenient until they collide on the same date. Totalling them against the balance available shows the failure risk, and a failed mandate usually costs a penalty from both the bank and the biller.

Formula

Autopay coverage

Total = mandates × average amount; shortfall = total - balance available

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 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
Figures are estimates for planning only. Prices, returns, inflation and personal circumstances all change. This is not financial or tax advice — speak to a qualified adviser before making decisions.

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

Frequently Asked Questions

What happens if a mandate fails?

Both the bank and the biller typically charge a fee, and repeated failures can affect your credit record.

How should mandates be arranged?

Cluster them a few days after payday and stagger large ones so no single date carries the whole burden.
