Schools may have to redraw budgets for the next academic year after the Department for Education admitted it miscalculated its funding plans.
But an update was published on Friday alongside an admission that the original version of the plans contained an incorrect estimate of pupil numbers.
But she said the amount promised to schools had to be recalculated because the department "uncovered an error made by DfE officials during the initial calculations".
The BBC has calculated that keeping to the originally planned increase of 2.7% per pupil would have meant the government having to find a further £370m to top up the overall schools budget.
Geoff Barton, general secretary of the Association of School and College Leaders, said: "This is an extremely unfortunate and frustrating error.
The union said in a statement that the government is "not paying attention to the crisis in education", adding: "Head teachers have planned for that money and budgets are pared to the bone."
