Savings & Goal Calculators
A savings goal isn't one number — it's a date. And the date moves every time a small leak you forgot about pulls money back out. These calculators show you both halves: the exact day you hit your target, and the quiet subtractions standing between you and it.
Start with the target: the savings goal calculator gives you the exact date your number lands, the vacation sinking fund calculator works backward to the weekly transfer a trip actually needs, and the F-You Money calculator puts a figure on the day work becomes optional. Then find the leaks: the buy now, pay later calculator totals your true balance across every Klarna and Affirm split, the 0% APR payoff calculator surfaces the deferred interest waiting at the end of a promo, and the free shipping calculator settles whether the filler item really beat the shipping fee. When the leak is interest, the balance transfer calculator and the student loan extra payment calculator show whether a fee or an extra $50 a month is worth it. No advice, no signup — just the math, run in your browser and gone when you close the tab.

How much do I need to save each month to hit a goal by a certain date?
Divide the amount you still need by the months until your deadline, then adjust for any interest your savings earn along the way. The savings goal calculator does this in reverse: enter your target and date, and it returns the exact monthly or weekly transfer required, plus the day you actually arrive.
How much money do I need to never have to work again?
A common benchmark is 25 times your annual expenses — the "4% rule" — so $40,000 a year in spending implies roughly $1 million invested. That's your financial-independence, or "F-You," number: the point where investment returns can cover your life and a paycheck becomes optional rather than required.
What is the real cost of buy now, pay later?
Buy now, pay later splits a purchase into installments that look interest-free, but the true cost is the invisible total: several active plans at once, easy to lose track of, with late fees and occasional interest. Tallying every open Klarna, Affirm, and Afterpay split usually reveals you owe far more than it felt like.
