Run the Numbers

The quick math smart shoppers and borrowers do before they buy, sign, or swipe. Free, instant, nothing saved.

True cost of a loan or financing

See the real monthly payment and how much you'll pay on top of the price.

Price of item

Extra fees

Interest rate (APR %)

Term (months)

Monthly payment—

Total interest + fees you'll pay—

Total you'll actually pay—

Enter the price, rate, and term to see the real cost.

Which size is actually cheaper?

Compare two products by price per unit (ounces, pounds, count — whatever's on the label).

Option A — price

Option A — amount

Option B — price

Option B — amount

Unit name (oz, lb, count…)

Option A — price per unit—

Option B — price per unit—

A bigger package isn't always cheaper — this tells you for sure.

Is this deal actually worth it?

See the real discount, the dollars saved, and what it costs each time you use it.

Original price

Sale price

Times you'll use it (optional)

You save—

That's—

Cost per use—

A discount only saves money if it's something you'd buy anyway.

Make your money grow

The "hidden" tool smart people use: compound interest. See what steady saving becomes.

Starting amount

Added each month

Yearly return (%)

Years

You put in—

Growth earned—

Ends up worth—

Rule of 72: divide 72 by your return % to see how many years it takes your money to double.

Credit card payoff

How long it really takes — and how much interest — at your current monthly payment.

Balance owed

Interest rate (APR %)

You pay per month

Time to pay off—

Total interest paid—

Total you'll pay—

Paying even a little more each month can cut months — and big interest — off the total.

Money in vs. money out

See what's left after the month's bills — and how much of your income you actually keep.

Monthly income (take-home)

Housing (rent / mortgage)

Food & groceries

Transportation

Debt payments

Everything else

Total going out—

Left over each month—

You're keeping—

A common target is keeping about 20% of take-home — but any positive number is progress.

Paycheck take-home (estimate)

A rough idea of what actually lands in your account. Adjust the tax rate to your situation.

Gross pay (per paycheck)

Est. income tax rate (%)

FICA (Social Security + Medicare)—

Estimated income tax—

Estimated take-home—

Rough estimate only — real take-home depends on your state, filing status, and deductions.

Tip & bill split

Tip and divide the check in one tap.

Bill amount

Tip (%)

Split how many ways?

Tip—

Total with tip—

Each person pays—

15% is standard; 18–20% for good service.

Rent you can comfortably afford

Based on your income and the rules planners and landlords use.

Your monthly income (gross, before tax)

Comfortable (25%)—

Standard max (30%)—

Stretch (35%)—

The classic rule: keep rent at or below 30% of gross income. Many landlords want income of about 3× the rent.

Trip / gas cost

What a drive actually costs you in gas.

Distance (miles)

Your car's MPG

Gas price ($/gallon)

Gas needed—

One-way cost—

Round-trip cost—

Handy for deciding if a far-away "deal" is really cheaper once gas is counted.

What small spends really add up to

That little habit — seen as a year, a decade, and what it could've grown into.

Amount each time

How often?

Per year—

Over 10 years—

If invested 10 yrs at 7%—

Not saying never — just worth seeing the real number behind a daily habit.

Reach a savings goal

How long it'll take at your current pace (add a return rate if it's invested).

Goal amount

Saved so far

Save per month

Yearly return % (optional)

Time to reach it—

Total you'll add—

Interest earned—

Enter a goal and a monthly amount to see your timeline.

Hourly rate

Hours per week

…or a yearly salary

Per week—

Per month—

Per year—

Salary → hourly—

Based on the hours per week you enter (uses 52 weeks a year).

Emergency fund target

The cushion that keeps a bad month from becoming a disaster.

Monthly essential expenses

Months of cushion

Saved so far

Target fund—

Still to save—

3 months is a solid start; 6 months is the classic goal. Count only true essentials.

What it costs in work hours

A purchase reframed as hours of your life — a surprisingly clarifying gut-check.

Price of the item

Your take-home hourly pay

Hours of work—

That's about—

"Is it worth X hours of my time?" is often a clearer question than the price tag.
