From "I want $30,000" to "I need $812/month".
A savings goal without a monthly number is a wish. This calculator converts any target — a house down payment, an emergency fund, a sabbatical — into the exact monthly deposit required by your deadline, accounting for your current savings and any interest your account earns. If the number is too high, extend the deadline or lower the goal until the plan fits your budget.
A house deposit, an emergency fund, a wedding, a sabbatical — every goal is a wish until it has a monthly number. People use this to convert "I want $20,000 in two years" into "$812 a month," and to find out honestly whether the plan fits the budget before committing to it.
A common target is 3–6 months of essential expenses. If your essentials cost $3,000/month, that is a $9,000–$18,000 goal. Enter it here with your deadline to get the monthly plan.
For goals under 2 years, interest moves the required deposit by only a few percent. For 5+ year goals in a high-yield account, it can reduce your required monthly deposit by 10% or more.
That is the calculator doing its job. Lengthen the timeline, reduce the goal, or split it into phases. A plan that fits your budget beats an ambitious plan you abandon in month three.
