How to Calculate Mileage Reimbursement Correctly

Claiming for business driving is straightforward arithmetic against a rate that changes annually — and using last year’s rate is how a claim gets queried or quietly underpaid.

What the Mileage Reimbursement does

Multiplies distance by a per-unit rate. Defaults to 0.67, which reflects a recent published business rate.

Check the current rate before claiming. These are revised at least yearly, sometimes mid-year when fuel prices move sharply, and the published figure is what your employer or tax authority will apply.

Open the Mileage Reimbursement and follow the settings and checks below.

Inputs

Setting	What it means
Distance driven	Default 250
Rate per mile/km	Default 0.67
Rate changes	At least annually — check before claiming
Rate is meant to cover	Fuel, wear, insurance, depreciation
Commuting	Usually not claimable
Records needed	Date, purpose, distance
Returns	Total reimbursement
Knows your jurisdiction?	No — you supply the rate

How to use it

1. Look up the current published rate for your country and year.
2. Enter the business distance — not commuting.
3. Keep a log of date, purpose and distance for each journey.

Practical advice

Log each journey as you make it, with the purpose written down. Mileage claims are among the most commonly queried expenses precisely because they are easy to estimate and hard to evidence after the fact — a contemporaneous log with dates and reasons settles a query in seconds, and a reconstructed one invites more questions.

Common questions

Can I claim my commute?

Usually not. Travel between home and your normal workplace is typically ordinary commuting rather than business travel in most tax systems. Journeys to a client, a temporary site or between offices generally do qualify — check your local rules.

What does the rate cover?

It is meant to cover the full running cost — fuel, servicing, tyres, insurance and depreciation — not fuel alone. That is why it is several times the fuel-only cost per mile.

Why does the rate change?

Because the costs it approximates change, particularly fuel. Authorities revise it at least annually and occasionally mid-year, so a claim submitted at last year’s rate will be adjusted or challenged.

What records do I need?

Date, purpose and distance for each journey, at minimum. Some employers want start and end points too. Keep it as you go — that is the whole difference between a claim that is paid and one that is queried.
