What it does: See how compounding turns APR into a higher APY — side-by-side. Typical inputs: APR (nominal) (%), Compounds / year. People often land here searching for apr, apy, compounding, effective rate. Demo defaults (apr (nominal) 5 %, compounds / year 12) currently resolve to APR 5%; APY 5.12% in the live panel — change any field to explore sensitivity. Who it helps: homebuyers, loan shoppers, investors, freelancers, and anyone comparing a bank quote to an independent worksheet. Nearby tools people often open next: apr to apy, effective interest, cd apy.

When to use / who it helps
- Reading a loan or savings quote that lists APR and APY differently.
- Teaching why more frequent compounding raises effective yield.
- Sanity-checking a marketing APY against the stated APR and schedule.
- Use the APR vs APY Comparator when you want a second opinion on a bank, broker, or app quote before you sign.
- Compare two scenarios side by side (rate, tenure, contribution) by changing one input at a time.
How to use
Steps
- Enter the nominal APR.
- Choose compounds per year.
- Read APY and the compounding lift.
- Re-run with another frequency to compare.
- Open the APR vs APY Comparator on MyCalcsWorld and skim the labeled fields before you type.
- Set APR (nominal) (%) — demo default is 5 %.
How to interpret results
- APY ≥ APR when APR ≥ 0 and n ≥ 1 (for standard positive rates).
- Larger n raises APY toward the continuous-compounding limit.
- Educational — product disclosures define the legal APY/APR labels in your region.
- On the APR vs APY Comparator, read the large primary result first, then secondary totals, then any chart or table.
- Each result is driven only by the labeled inputs (APR (nominal) (%), Compounds / year); anything not on the form (fees, holidays, clinical adjustments) is outside this estimate.
Common mistakes & gotchas
- Comparing one product’s APR to another’s APY.
- Forgetting that loan APR may include fees while deposit APY usually does not use the same fee rules.
- Assuming continuous compounding when the product compounds monthly.
- Entering APR when the APR vs APY Comparator expects a nominal note rate (or the reverse) — that quietly skews payments.
- Forgetting fees, insurance, GST, or escrow that your real product includes outside the core fields: APR (nominal) (%), Compounds / year.
Worked example
Worked example — 5% APR compounded monthly
- APR = 0.05; n = 12.
- APY = (1 + 0.05/12)^12 − 1 ≈ 5.116%.
- Lift ≈ 0.116 percentage points from compounding.
- Open the APR vs APY Comparator (apr vs apy) and note the starting defaults (apr (nominal) 5 %, compounds / year 12). These are demo numbers — not recommendations.
Result: With defaults (apr (nominal) 5 %, compounds / year 12), the APR vs APY Comparator shows: APR 5%; APY 5.12%. Re-run with your own numbers for a personalized estimate — illustrative only, not professional advice.

Frequently asked questions
Why is APY higher than APR?
Because interest compounds inside the year, so the effective annual yield exceeds the nominal rate.
What n should I use for daily?
Often 365 (sometimes 360 in banking conventions). Match the disclosure when you can.
Does this include loan fees?
No — it converts a nominal rate given compounding frequency. Fee-inclusive APR rules differ by product and country.
How is this different from APR to APY Converter?
Same math family — this comparator emphasizes the side-by-side lift; the converter is a focused APR→APY tool.
Is continuous compounding supported?
Use a very large n as an approximation, or the continuous compound tool when available.
