Frequently asked questions

What is Equity Ratio Calculator?

Equity divided by total assets, with the complementary debt ratio, the equity multiplier and a clear reading when equity is negative.

When would I actually use this?

Planning a deposit, a safety net or a large purchase: how much to put aside each month, and how long a target takes at a given rate.

What is the most common mistake?

Reading a nominal rate as if it were real. Inflation is subtracted from the return, not from the capital, so a 3% account during 4% inflation loses purchasing power every year.

How is Equity Ratio Calculator different from Acid-Test (Quick) Ratio Calculator?

They sit next to each other but answer different questions. Acid-Test (Quick) Ratio Calculator: add cash, securities and receivables, divide by current liabilities, and see exactly what excluding inventory and prepaid expenses costs the ratio. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Goodwill to Assets Ratio Calculator is the closest one after this: Measure how much of the balance sheet is goodwill, against equity and tangible book value, and see what a full impairment would destroy.

What else is worth having open alongside it?

Retention Ratio (Plowback) Calculator and Cost of equity calculator (CAPM & DDM) — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Compound interest is arithmetic, so the maths is exact for the rate you enter. Real accounts vary in compounding frequency, tax treatment and whether interest is credited before or after a deposit.

ExplainerThree Different Rules Get Called "The 529 Rule"Qualified expenses, the K-12 cap and state tax treatment are three separate rules, and only the first two are federal. The K-12 cap doubled to 20,000 dollars for tax years from 2026; a federally qualified withdrawal can still be a state recapture event.ExplainerCollege Costs Compound for Eighteen Years Before Anyone EnrolsA four-year public in-state budget is 30,990 dollars today. Eighteen years out at 4 percent cost inflation the same four years cost 266,593 — 2.15 times the sticker you can see now. And the sticker was never the price: the average net cost of attendance is 21,340.ExplainerThe Alimony Formulas Agree on the Amount and Not on the DurationTwo of the three published US alimony guidelines are the same formula written twice: on 150,000 and 30,000 dollars of gross income both give 3,250 a month. What separates them is duration — 2.1 years or 10.5 — and that turns one marriage into 81,900 or 409,500.ExplainerChild Support Is a Shared Cost, Not a Slice of One SalaryIncome shares asks what two parents together would have spent, then splits it. On $5,000 and $3,000 with two children the schedule says $2,257.37, the shares are 62.5 and 37.5 percent, and after 90 overnights the order is $1,301.47 a month.ExplainerOne Point of Discount Rate Moves a Perpetuity by a QuarterA payment of 1,000 a year is worth 20,000 at a 5 % discount rate and 25,000 at 4 %. The formula is a single division, and that is exactly why the input matters more than the arithmetic.ExplainerTwo Accepted Models, Two Points Apart on the Same CompanyCAPM and the dividend growth model both compute the cost of equity. On one set of inputs they give 9 % and 7 % — and the choice between them decides a valuation more than any figure inside either.
