Moving contingency planner

Turn uncertainty into a visible reserve

A contingency is money set aside for identified uncertainty, not a promise that nothing will exceed the budget. This planner lets you choose which expense lines need a percentage reserve and model one additional stress event separately. It is useful when some quotes are still provisional or a key date may change.

Start with realistic base costs. A reserve cannot fix an omitted removal bill or an unpriced week of accommodation. Enter the expenses you are examining and mark only those that should contribute to the percentage calculation. Costs with a well-defined fixed amount may need different treatment from an hourly service whose duration remains uncertain.

How the reserve is calculated

The base expense budget is the sum of every entered expense. The selected reserve base is the sum of rows where Apply reserve is checked. Reserve equals that selected base multiplied by your chosen percentage. Base plus reserve then adds this allowance to the full base budget, including unselected expenses.

The stress-scenario figure adds one further entered event cost to base plus reserve. It is shown separately so you can see the difference between a general allowance and a specific event. The percentage is your planning choice; the default displayed in the form is not a verified industry recommendation or a universal minimum.

Be clear about what the stress amount represents. If the base already includes three storage weeks and your concern is a fourth, enter the additional week's relevant cost, not the price of all four weeks again. If the reserve was chosen specifically to cover that same event, decide whether adding both would intentionally model a tougher case or simply duplicate the risk.

Worked example: selected expenses and one delay

These are hypothetical figures. Enter removals at £800, packing at £100 and cleaning at £150. The base expense budget is £1,050. Select removals and packing for a 10% reserve but leave cleaning unselected.

The selected reserve base is £900, the reserve is £90 and base plus reserve is £1,140. Enter £180 as one extra accommodation-and-storage event. The stress scenario including reserve becomes £1,320. That result is not a prediction that the event will happen; it is the amount you chose to examine.

If you select cleaning too, the reserve becomes £105 and the stress result rises to £1,335. This change helps explain exactly which assumptions created the extra £15, rather than burying an unexplained uplift inside the total moving bill.

Typical moving uncertainties to consider

Useful scenarios include supplier waiting time, another hire day, a storage extension, an unplanned overnight stay or a necessary access arrangement. Price the event from the relevant quote or your own spending limit where possible. Not every uncertainty needs a percentage: a known extra-day rate may be better represented as the separate stress amount.

Keep alternative events separate when they could not happen together. For instance, one plan might use overnight accommodation and next-day delivery, while another uses a longer storage booking and a different move date. Adding every worst case into one unexplained number can make the result less useful than two clearly described scenarios.

Use the removal comparison to identify actual waiting terms, the storage comparison for billing extensions and the date planner to test another schedule.

Carry the reserve into the main budget once

The main moving budget has its own selected-expense reserve. If you use the same contingency there, do not also add this tool's reserve as an expense without adjusting the main reserve settings. Decide which calculation is the authoritative version of your plan.

Revisit the allowance when quotes firm up or uncertainties are resolved. You may be able to release part of it, or discover that an unpriced issue needs a specific line. The uncertain-date guide helps coordinate the practical fallback alongside the money.

How to use this tool

1. Identify uncertain expenses. Enter the base costs you want to assess and select the lines where a percentage reserve is useful. Keep omitted or wholly unpriced costs on a separate action list.

1. Choose the assumptions. Set your reserve percentage and one additional stress-event cost. Describe the event in your own planning notes so the amount remains understandable later.

1. Check for duplication. Read base, reserve and stress totals separately. Transfer the chosen allowance into your main budget only once, and review it when dates or written quotes change.

Frequently asked questions

Is the default percentage an industry-standard contingency?

No. It is an editable starting assumption. Choose an allowance based on the uncertainties, supplier terms and financial flexibility of your own move.

Why is the reserve smaller than a percentage of my whole budget?

The percentage applies only to checked expense lines. Unselected expenses remain in the base budget but do not contribute to the reserve calculation.

Should I include every possible bad event in the stress amount?

Only if that combination is a meaningful scenario you deliberately want to examine. Mutually exclusive alternatives are usually clearer as separate calculations, with their assumptions recorded.
