Amortization Tables: See Exactly Where Every Payment Goes
An amortization table reveals the hidden truth of every loan payment. On a $350K mortgage at 6.5%, payment #1 splits $1,108 to interest and $1,104 to principalโnearly 50/50. Payment #360: only $12 to interest and $2,200 to principal. Adding $200/mo moves the crossover point to year 11 and saves $68K.

Early payments are mostly interest; later payments go more to principal. Extra payments applied to principal reduce total interest and shorten the loan. Even $50โ200 extra per month can save thousands over a 30-year mortgage. Lump-sum payments (tax refund, bonus) have the same effect when applied to principal.

Why: Amortization tables matter because they show how interest is front-loaded. Early payments are mostly interest; later payments go to principal. Seeing the crossover pointโwhen principal exceeds interestโmotivates extra payments. Even $50โ200 extra per month can save thousands over 30 years.
How: Enter principal, rate, term, and optional extra payments (monthly, annual, or lump sum). The calculator generates a full amortization schedule with principal, interest, balance, and cumulative interest per payment. Download as CSV for your records.

Loan Summary
Step-by-step:
Your amortization table shows how each payment is split between principal and interest. Extra payments reduce total interest and shorten the loan term.

๐ก Money Facts
On a $350K 30-year loan at 6.5%, you pay ~$444K in interestโmore than the principal.
โ Amortization
Adding $200/month to a $350K mortgage can save ~$68K and cut 7+ years off the term.
โ Extra Payment Impact
Biweekly payments (half every 2 weeks) = 13 full payments/year, accelerating payoff.
โ Payment Strategies
Refinancing to a lower rate can reduce monthly payment and total interest significantly.
โ Refinancing
Interest is front-loaded: first 5 years of a 30-year loan pay mostly interest.
โ Loan Structure
Some lenders apply extra payments to next month's payment; specify "principal only".

๐ The Hidden Truth of Every Loan Payment
An amortization table reveals the hidden truth of every loan payment. On a $350K mortgage at 6.5%, payment #1 splits $1,108 to interest and only $1,104 to principal โ nearly 50/50. But payment #360 (the last): only $12 to interest and $2,200 to principal. The 'crossover point' where principal exceeds interest occurs at payment #202 (month 17 of year 17). Seeing this table motivates extra payments โ adding $200/mo moves the crossover to year 11 and saves $68K. Every borrower should see their amortization table.

๐ Did You Know?
๐ How Amortization Works
An amortization table shows how each payment is split between principal and interest. The monthly payment stays fixed, but the interest portion decreases over time while the principal portion increases.
Standard Payment
M = P ร r(1+r)^n / ((1+r)^n โ 1). Same amount each month until payoff.
Extra Payments
Any amount above the required payment goes to principal, reducing future interest.
๐ฏ Expert Tips
Start Small
Even $50โ100 extra per month compounds into significant savings over 30 years.
Windfall Strategy
Apply tax refunds, bonuses, or inheritances directly to principal for maximum impact.
Biweekly Option
Pay half the monthly amount every 2 weeks = 13 full payments/year, shortening the loan.
Verify With Lender
Confirm extra payments go to principal, not future payments. Some loans have prepayment penalties.

โ Frequently Asked Questions
What is an amortization table?
An amortization table is a schedule showing how each loan payment is split between principal and interest. Early payments are mostly interest; later payments go more to principal. The table reveals the true cost of borrowing and motivates extra payments.
How to read an amortization schedule?
Each row shows: payment number, total payment, principal portion, interest portion, extra payments, and remaining balance. Principal increases over time while interest decreases. The crossover point is when principal exceeds interestโtypically around year 17 on a 30-year mortgage.
What is an amortization schedule for a mortgage?
A mortgage amortization schedule shows month-by-month how your fixed payment splits between principal and interest. On a $350K loan at 6.5%, payment #1: $1,108 interest + $1,104 principal. Payment #360: $12 interest + $2,200 principal. The dramatic shift motivates extra payments.
Yearly vs monthly amortization table?
Monthly tables show every payment; yearly tables aggregate by year (total principal paid, total interest paid, ending balance). Monthly is best for seeing the crossover point and extra-payment impact. Yearly is useful for tax planning and annual summaries.
How do extra payments affect amortization?
Extra payments reduce principal immediately, so less interest accrues. Adding $200/mo to a $350K mortgage at 6.5% moves the crossover point from year 17 to year 11 and saves ~$68K. The table shows exactly when payoff accelerates.
What is negative amortization?
Negative amortization occurs when payments are below the interest dueโthe unpaid interest gets added to the balance. On a $200K ARM with payments below interest, the balance can INCREASE from $200K to $220K. The table shows this danger clearly.
