Unexpected costs are normal in project delivery, but donors do not always allow a general contingency line. NGOs therefore need to distinguish between prudent risk planning and creating an unsupported reserve that the donor may reject.
Check whether the donor allows contingency
Some funders permit a defined contingency percentage or management reserve. Others expect every cost to be tied to a specific activity or budget category. Review the budget guidance before adding a general reserve.
Use risk analysis to identify where uncertainty sits
Instead of adding one large unexplained contingency, identify the real risks: exchange-rate movement, fuel prices, venue costs, security, procurement lead times or seasonal transport. Where possible, build realistic assumptions into the relevant budget lines.
A grant risk register can help show which uncertainties deserve financial planning.
Avoid using contingency as hidden padding
A donor may question a reserve that has no explanation, especially if the budget already includes conservative unit costs. The purpose of contingency should be transparent and proportionate to the uncertainty being managed.
Know who can authorize use of the reserve
If a contingency line is approved, define when it can be used and whether donor approval is still required. A budget line labelled “contingency” does not automatically give unrestricted discretion.
Use scenario planning where contingency is not allowed
When the donor does not permit a contingency line, prepare internal best-case, expected-case and high-cost scenarios. This helps management understand the financial risk without changing the submitted budget structure.
Example
An NGO planning field activities in a remote area expects transport prices to fluctuate. Instead of adding a vague 10 percent contingency, it might document the number of trips, expected fuel range and a realistic unit-cost assumption. If the donor explicitly allows a reserve, the remaining uncertainty can then be explained clearly.
A practical decision checklist
- Does the donor allow contingency?
- What specific risk is being covered?
- Can the uncertainty be budgeted directly instead?
- Is the amount proportionate?
- Who can authorize use?
- Does donor approval still apply?
- How will use of the reserve be reported?

Distinguish contingency from inflation
Expected inflation is not the same as an unforeseen contingency. If prices are likely to rise during a multi-year project, build a reasonable inflation assumption into the relevant cost lines where donor rules permit. A contingency should cover uncertainty that cannot be estimated as directly.
Document how the reserve was used
If the donor approves a reserve, maintain a simple log showing the date, amount, reason, approver and budget line affected. This protects the reserve from becoming an informal pool of money that staff use whenever another category is short.
At each forecast review, ask how much of the reserve remains and whether the original risks still justify it. If the reserve is no longer needed, the team may need to discuss reallocation or return of funds depending on donor rules.
When preparing the proposal narrative, explain uncertainty in plain language rather than relying on the word “contingency.” A donor is more likely to understand a reserve that is connected to identifiable implementation risks, a documented approval process and clear reporting than a percentage added with no explanation.
Management should also compare contingency use across projects. If the same “unexpected” cost appears repeatedly, it may no longer be a contingency issue; it may be a budgeting weakness that should be built into future proposals from the start.
Frequently asked questions
What is a grant contingency or management reserve?
It is budgeted flexibility for uncertain costs or risks, but the exact treatment depends on donor rules and organizational policy.
Are contingencies always allowed?
No. Some donors prohibit general contingencies or require them to be tied to specific allowable cost categories.
How should an NGO decide the amount?
Base it on identifiable risk and donor rules rather than adding an arbitrary percentage simply to create spare budget.
Who should approve it?
Finance and leadership should review the rationale, with donor approval where the grant rules require it.
What if a donor does not allow contingency lines?
Manage uncertainty through realistic assumptions, sensitivity analysis, phased procurement, or approved budget flexibility instead of hiding reserves in other costs.
Conclusion
Contingency should reflect real risk and donor rules, not become hidden budget padding. Your NGO should document the uncertainty it is managing and use transparent, allowable methods to create flexibility.
