Budget & big purchases calculators
10 free calculators · instant · nothing you enter is uploaded
Budgets fail quietly: nothing goes wrong on any single day, and yet the month ends short. These calculators put a number on the big, lumpy costs people tend to underestimate — a wedding, a holiday, a house deposit, a car — and turn them into a monthly saving target you can actually act on. Start with the total, work back to what you need to set aside each month, and decide whether the timeline or the amount has to give.
