Credit Card Miles Calculator
Spending $2,000 a month on a miles card sounds rewarding until you ask what those miles are actually worth after the annual fee. This credit card miles calculator turns your monthly spending into miles at a base rate and a higher bonus category rate, adds any first-year signup bonus separately, then values the miles at a cents-per-mile figure you control.
That last part matters. A mile has no fixed price: the same balance can be worth 1.7 cents a mile on a well-chosen flight or under a cent cashed out, and the verdict on a $95 fee card flips with that choice.
Enter your own card earn rates from its terms: this tool uses generic inputs and invents no card programs. The mile value is your estimate of what a mile is worth for how you redeem.
Quick Answer
Key takeaways
- Bonus spending is part of total spending, not extra. Only the non-bonus remainder earns the base rate, and tools that add both rates on the full amount overstate your miles.
- The fee break-even is small when you spend heavily and brutal when you do not: at 1.5 cents a mile, a $95 fee needs about 6,333 miles a year before the card pays anything.
- Keep the signup bonus in year one only. A card that looks rich in year one can be ordinary from year two onward.
- Interest beats miles every time. If you carry a balance, price the APR before you price the rewards.

How to use this miles calculator with your own card
Start with your real monthly spending, not the spending you plan in a good month. Then copy the base and bonus earn rates from your card terms, enter only the share of spending that genuinely falls in the bonus category, and set the mile value to match the redemption you would actually book.
Read the result in order. Annual miles tell you the size of the pile. Annual value prices it. Net annual value, after the fee, is the number to compare against a no-fee card or a simple cash back card. If you are weighing two rewards cards against each other rather than pricing miles, the credit card reward calculator compares cards head to head on the same spending.
The miles formula, step by step
The math is four multiplications and one subtraction, and the order matters because bonus spending sits inside total spending.
Two checks keep the inputs honest. Bonus category spending cannot exceed total monthly spending, because those dollars are already counted once. And the mile value must be above zero: a mile you never redeem is worth nothing, and entering a fantasy value of 3 or 4 cents makes every fee card look like a bargain.
Worked example: $2,000 a month, two earn rates, one fee
The calculator is pre-filled with this case, and every figure below is what it returns when you press Calculate.
| Step | Calculation | Result |
|---|---|---|
| Non-bonus spending | $2,000 minus $600 | $1,400 |
| Monthly miles | $1,400 x 2 + $600 x 3 | 4,600 miles |
| Annual miles | 4,600 x 12 | 55,200 miles |
| Annual value at 1.5 cents | 55,200 x $0.015 | $828.00 |
| Net after the $95 fee | $828.00 minus $95 | $733.00 |
| First year with 60,000 bonus miles | 115,200 miles x $0.015, minus fee | $1,633.00 net |
| Fee break-even | $95 / $0.015 | About 6,333 miles |
Notice the scale of each piece. Moving $600 of spending from 2 miles to 3 miles per dollar adds 7,200 miles a year, worth $108 at 1.5 cents: useful, not life-changing. The signup bonus is worth $900 in year one and nothing after, which is why the tool refuses to fold it into the ongoing annual figure.
What a mile is worth depends on the seat you book
A mile is worth what it saves you on a booking you would have paid cash for, divided by the miles it cost. Published valuations disagree because they measure different bookings: NerdWallet's 2026 study put American AAdvantage at 1.7 cents and Delta SkyMiles and United MileagePlus at 1.2 cents, while other monthly valuations rank the same programs differently. Treat any published figure as a starting guess, then test your own likely redemption.
The spread inside one program is wider than the spread between programs. A saver award on an expensive route can clear 2 cents a mile. A last-minute domestic award priced dynamically can fall under 1 cent. Cash back, gift cards, and merchandise usually sit at the bottom, often around 0.6 to 1 cent. If your realistic redemption is cash, enter 1 cent or less and let the verdict be honest. Readers pricing miles they already hold in an airline program, rather than miles a card will earn, can cross-check with the airline miles calculator.
Every row above uses the same 55,200 annual miles from the worked example. Only the valuation moves, and it moves the net result from $457.00 to $1,009.00 after the fee. That range is the real answer to "what are my miles worth": a range, set by your redemption habits.
When the annual fee stops paying for itself
A fee card has to clear two hurdles, not one. First it must earn enough miles to cover its own fee, the break-even figure in the result. Then it must beat the no-fee alternative you would otherwise use, because miles you would have earned anyway are not a gain.
Low spenders fail the first hurdle quietly. At $400 a month and 2 miles per dollar, you earn 9,600 miles a year, worth $115.20 at 1.2 cents: barely over a $95 fee, before counting the no-fee card you gave up. That is why fee cards are marketed on perks and credits rather than earn rates.
A miles card tends to win when
- You pay the statement balance in full every month
- You redeem for flights you would have bought anyway
- Your spending clears the fee break-even early in the year
- You use the card long enough that year-two math still works without a bonus
Cash back tends to win when
- You redeem for cash, gift cards, or merchandise
- You travel rarely or book the cheapest fare regardless of airline
- Your monthly spending is a few hundred dollars, not a few thousand
- You sometimes carry a balance and pay interest
The interest test every miles card fails
Miles are priced in cents; interest is priced in tens of dollars. According to the Consumer Financial Protection Bureau guidance on how card interest is calculated, issuers charge interest on your average daily balance, so a carried balance grows a charge every day it sits there.
Run the comparison once and it settles the question. Earning 4,600 miles in a month at 1.5 cents gives you $69 of travel value. Carrying a $3,000 balance at 22.99 percent APR for that same month costs about $57.48 in interest, and the interest repeats every month while the miles require fresh spending. If paying down the balance is the real job, the credit card extra payment calculator shows what an added monthly payment does to the payoff date, and a points balance can be priced on its own with the card points calculator if your program uses points rather than miles.
What competing miles calculators miss
Most generic miles tools reviewed for this page share the same few gaps.
Gap 1: one flat earn rate. Several tools multiply all spending by a single miles-per-dollar figure. Real cards pay a higher rate on a bonus category and a lower rate on the rest, so a flat rate either inflates or undersells the result. Here the bonus slice is separated and cannot exceed total spending.
Gap 2: the signup bonus baked into every year. Some tools add the welcome bonus and then project the total across multiple years, which counts a one-time gift again and again. This calculator reports first-year and ongoing annual value as two different numbers.
Gap 3: a baked-in mile value presented as fact. Tools that hard-code 1 or 2 cents per mile hide the single most uncertain input. Here the value is an editable field with the verdict recalculated around it, plus the fee break-even in miles so you can see how sensitive the answer is.
Gap 4: no named-card honesty. Card-specific calculators from rewards sites are deeper for that one card, but they assume you hold it. This page stays program-neutral: you bring your own rates from your own card terms, and the tool invents no card programs.
Frequently Asked Questions
Multiply one month of spending by its earn rate, add the bonus category the same way, then multiply the monthly total by 12. On $2,000 a month with $600 at 3 miles per dollar and the rest at 2, that is 4,600 miles a month and 55,200 miles a year, before any signup bonus.
There is no fixed rate. Published 2026 valuations for major US airline programs mostly sit between 1.2 and 1.7 cents per mile for flight redemptions, and cash or merchandise redemptions usually pay less. This calculator lets you set the value yourself, because the redemption you will actually book is the one that counts.
Only in the first year, and the calculator keeps it separate for that reason. Ongoing annual miles come from spending alone. First-year miles add the one-time bonus on top, so a large bonus cannot hide a weak everyday earn rate in later years.
Divide the annual fee by your value per mile in dollars. A $95 fee at 1.5 cents per mile needs about 6,333 miles a year before the card starts paying you. The calculator shows this break-even figure with every result.
Interest usually wipes out the miles. One month of interest on a $3,000 balance at a typical card APR costs more than a month of miles earns for most spenders. Miles cards reward people who pay in full; if you carry a balance, a lower APR matters more than any earn rate.
Miles win when you redeem them for flights at a value above the cash back rate you could have earned, and cash back wins on certainty. A 2 percent cash back card pays 2 cents per dollar with no award hunting. Compare the net annual value here against that simple benchmark before you choose.
It depends on the program. Many bank-issued miles stay valid while the account is open, while airline miles transferred to a loyalty program can expire after a period of inactivity. The Consumer Financial Protection Bureau has flagged rewards expiration and forfeiture as a common source of complaints, so check your own program terms.
Because the bonus dollars are not extra dollars. If you spend $2,000 in total and $600 of it falls in a bonus category, only $1,400 earns the base rate. Entering bonus spending above total spending would double count the same purchases, so the calculator rejects it.
