See months to debt free, interest paid, and fund balance. _Interactive tool: open [the web page](https://budget44.com/tools/emergency-fund-vs-debt-payoff-calculator/) to use it. This Markdown copy has the text only._ The highlighted cell in each column is the best result for that column. No single plan wins them all, which is the whole point of the comparison. With nothing owed there is no strategy to choose. Set the target, automate the transfer, and the only variable left is how much you send. Watching both columns at once is the honest view. A falling balance next to an empty fund is a plan with no slack in it. Interest accrues monthly on the balance carried into the month, before that month's payment is applied, which is how a card statement works and is the conservative reading. Savings interest is shown before tax. The APY is treated as a simple monthly rate of APY divided by 12. The minimum payment is paid in every strategy until the balance clears, then it joins the spare cash going into the fund. No new borrowing, fee, or change in income is modelled, and every figure is held in whole cents until it is displayed. ## Why this is a real trade-off, not a math problem The rate spread says debt first, and it says it loudly. A 22% balance against a 4% savings account is an 18 point gap, so on paper every dollar you put in savings instead of against the card costs you money. That arithmetic is correct and it is also incomplete. What the spread does not price is the month you have $0 in the bank and the car needs $800. There is exactly one place that $800 can come from, and it is the card you have spent nine months paying down, at the same APR you were trying to escape. A plan that leaves you with no cushion for two years is not the cheaper plan. It just borrows the 22% back later. So this page reports both sides: interest paid, and the months you spend below your fund target. ## The phased plan most advisers actually recommend The personal finance guides mostly agree here, and what they agree on is a sequence rather than a side. Put a starter fund of $1,000 to $2,000 in place. Then send everything spare at the high-rate debt until it is gone. Then build the fund back up to three or six months of essential expenses, using the money that was going to the card. The reason that ordering works is the size of the starter fund, not the idea behind it. A $1,000 target takes two or three months to fill on $400 of spare cash, and on this page's defaults ($6,000 at 22.5%, $500 already saved) that delay costs $204 in extra interest against the $777 the debt-first plan pays anyway. You are buying most of the protection for a quarter more interest. Set the fund target chip to the $1,000 starter and put the fund-first row next to the debt-first row: the interest difference is usually smaller than people expect, and it is the whole argument. ## How to read the three strategies Start with the interest column, because that is the number the rate spread already told you about. Debt first almost always wins it. Then move one column left to "debt free in" and one column right to "fund target hit in", and look at what the win cost. Take the defaults on this page: $6,000 at 22.5%, a $150 minimum, $400 spare, $500 already saved. Debt first clears the balance two months sooner and pays $204 less interest, but the fund barely moves: savings interest alone drifts it from $500 to $520 by month 12, and it does not pass $1,000 until month 14. Fund first tops the starter target up in two months, pivots the full $400 at the balance, and finishes at month 15 with the cushion already in place. The last column, "fund when debt clears", is the one people skip and should not. It is the answer to "what does the day after look like". A plan that ends with the debt gone and the fund empty has moved the risk rather than removed it. The split is worth its extra interest when your income is variable, when you are the only earner, or when there is no family backstop behind you. When your job is steady and someone could cover one bad month, the split is usually just a slower version of debt first, and the extra interest buys less than it looks like it does. If the spare-cash figure itself is the shaky part, run it through the [savings rate calculator](https://budget44.com/tools/savings-rate-calculator/) as a share of income, or the [irregular income budget calculator](https://budget44.com/tools/irregular-income-budget-calculator/) if no two months look alike. Once the target is set, the [savings goal calculator](https://budget44.com/tools/savings-goal-calculator/) sizes the monthly contribution and the date. ## Turning the plan into a month you can actually run Every row on this page rests on one input: the spare cash figure. Guess it high and the plan quietly fails in month four, which is the month the fund gets raided and the comparison stops meaning anything. The only way to know the number is to watch a few real months go past. That is the loop Budget44 is built for. The card lives as a liability account, so charges and payments both post against it and the balance falls where you can see it. The fund lives as a saving goal, with Emergency Fund among the built-in presets, and contributions post against the target. Net worth shows both sides moving at once, which is exactly the picture the comparison table is trying to give you: the balance going down and the cushion going up, on the same screen. Recurring bills on six cadences and the calendar's recorded-versus-projected view are what turn "I think I have $400 spare" into a number you can trust. It all stays on the device, with amounts held as integer minor units so the totals stay exact to the cent. Picked your sequence?

Both, in that order. Put a small starter fund in place first (most guidance says $1,000 to $2,000), then send everything spare at the high-rate debt, then build the fund back up to three or six months once the expensive debt is gone. The starter fund costs very little in extra interest and it stops the next repair bill going straight back onto the card you just paid down. ### How much emergency fund should I have before I attack debt? A starter fund of $1,000 to $2,000 covers one ordinary emergency, which is the point of it. Set the fund target chip to the $1,000 starter and read the "fund first" row: for most balances it reaches the target within a few months and adds only a small amount of interest. The full three to six months of essential expenses comes after the expensive debt is cleared. ### At what interest rate does paying off debt beat saving? Around 7 to 8% is the line most guidance draws. Above it, clearing the balance is a guaranteed return that beats any safe savings yield. Below it, filling the fund first is usually the better call. This page compares the two rates you actually entered rather than assuming a threshold, so the rate gap row tells you which side of the line you are on. ### Can I build savings and pay off debt at the same time? Yes, and the split row puts a price on it. Splitting spare cash normally lands between the other two on interest, and it puts money in the fund from month one instead of month thirteen. Watch the fund target column though: against a full three or six month target, debt first can still cross the line first, because the whole payment pivots to savings the month the balance clears. The extra interest is worth paying when your income is variable or you are the only earner; if your job is steady and someone else can cover a bad month, the faster payoff usually wins. For variable pay, set the spare-cash figure with the [irregular income budget calculator](https://budget44.com/tools/irregular-income-budget-calculator/) first. ### Is a $1,000 starter emergency fund actually enough? Not for a job loss, and it is not meant to be. It is sized to cover one ordinary emergency (a repair, an insurance excess, a vet bill) so the balance you are paying down does not grow back while you pay it. Three to six months of essential expenses is the real target, and it comes after the high-rate debt is gone. ### Should I raid my emergency fund to pay off a credit card? Only down to the starter level, and only if what is left still covers a normal emergency. Cash earning 4% while a 22% balance sits against it costs you the gap every month, so the arithmetic favors paying. Draining the fund to zero usually just puts the balance back on the card at the same APR the first time something breaks. ### Does it matter whether I use the snowball or avalanche method here? Not for this comparison. Snowball (smallest balance first) and avalanche (highest rate first) change the order in which you clear multiple debts. This calculator treats everything you owe as one balance at one average rate, so the fund-versus-debt sequencing question comes out the same either way. Avalanche pays less interest overall, snowball gives you a cleared account sooner. ### Does this calculator send my numbers anywhere? No. Every figure is worked out in your browser, nothing is sent to a server, and there is no sign-up or email wall. Budget44 works the same way: accounts, budgets and saving goals stay in a local database on your device. ## Related Tools - [Credit Card Payoff Calculator](https://budget44.com/tools/credit-card-payoff-calculator/): See how long your credit card takes to pay off, the interest it costs, what extra payments save, and the payment needed to clear it in 12, 24 or 36 months. - [Debt-to-Income Ratio Calculator](https://budget44.com/tools/debt-to-income-ratio-calculator/): Work out your front-end and back-end debt-to-income ratio, check it against the 28/36 rule, and see the payment cut or income needed to reach 36%. - [Student Loan Payoff Calculator](https://budget44.com/tools/student-loan-payoff-calculator/): See how long your student loans take to clear, the total interest they cost, and how many months and dollars an extra payment each month saves you. - [50/30/20 Budget Calculator](https://budget44.com/tools/50-30-20-budget-calculator/): Split your monthly take-home pay into needs, wants and savings, compare the targets against what you actually spend, and try 70/20/10 or a custom split.
