Frequently asked questions

What is Effective Yield Calculator?

Convert a nominal rate into the effective annual yield for any compounding frequency, with APR and APY side by side.

When would I actually use this?

Comparing two investments that pay at different times, deciding whether a project clears its cost of capital, and sanity-checking a valuation someone else produced.

What is the most common mistake?

Trusting a valuation without asking what share of it comes from the terminal value. Past 70%, the answer is an assumption about the distant future dressed up as a calculation.

How is Effective Yield Calculator different from Capital Gains Yield Calculator?

They sit next to each other but answer different questions. Capital Gains Yield Calculator: compute the capital gains yield from the purchase and current price, with dividend yield, total return and the annualised equivalent. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Yield farming APY calculator is the closest one after this: Turn an advertised APR into the real APY once rewards are compounded, and see the final value and yield over your chosen period. Compounding frequency is the lever: the more often you harvest and re-stake, the wider APY opens above APR.

What else is worth having open alongside it?

Dividend yield calculator and Tax-equivalent yield calculator — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Discounting, IRR and payback are defined identically everywhere, so the arithmetic is not in dispute — the assumptions you feed it are. Change the discount rate by a point and re-read the answer.

ExplainerTax-Equivalent Yield: Comparing a Tax-Free Bond With a Taxable OneTaxable-equivalent yield = tax-free yield ÷ (1 − marginal rate). A 3.00 percent tax-free yield is worth 3.85 percent at a 22 percent marginal rate and 5.07 percent at 40.8 percent. The trap is that it is the marginal rate, surtaxes and social levies included — leaving them out costs 0.85 points of yield.ExplainerPrice Return, Total Return and Yield Are Three Different NumbersThe index quoted in the news is almost always a price index. At 5 percent price growth and a 2.5 percent reinvested yield, 30 years turn $10,000 into $43,219 on price and $90,656 on total return — the price measure misses 58.8 percent of the gain.ExplainerPaying Off a Loan Early: What Actually ChangesAn overpayment earns exactly the loan's rate, risk-free and after tax. On $200,000 at 5.00 percent over 25 years, $20,000 paid at the start saves $42,092 of interest; the same sum at year 16 saves $11,088; applied to the payment instead of the term it saves only $15,075.ExplainerCompounding Frequency, and Where Continuous Compounding Comes From(1 + r/n)^n rises with n but converges on e^r. At 6 percent, monthly and continuous compounding differ by $1.59 on $10,000 over a year. At 24 percent the same gap is $30.07, and over thirty years it is 7.4 percent of the balance.ExplainerDividend Reinvestment: What Actually Drives the DifferenceReinvesting a 3 percent yield for 30 years turns 100 shares into 242.7 and multiplies the final position by exactly that factor: $32,434 becomes $78,726. Tax at 30 percent on each dividend costs $18,223 of it — nearly two and a half times the tax actually paid.GuideYield Farming: What an Advertised APY Actually PaysThe number on the farm's front page is a gross figure before every subtraction. Here is a 120 percent APY walked down, one layer at a time, to the 33.6 percent that actually landed — plus why APR and APY are not the same number.
