How this calculator works

Calculates fixed-rate loan scenarios with amortized, deferred payment, and bond-style payoffs. It supports flexible compounding and payback frequencies, plus a monthly or yearly schedule.

Inputs

Loan amount or face value (for bonds)
Annual interest rate (APR)
Loan term length in years
Start month and year for payoff date estimates
Loan type (amortized, deferred, bond)
Compounding frequency (including continuous)
Payback frequency for amortized loans

Outputs

Payment per period (amortized loans)
Amount due at maturity (deferred loans)
Amount received (bond proceeds)
Total interest paid or accrued
Monthly or yearly schedule summary
Estimated payoff date based on the start date

Assumptions

Fixed rate and equal periodic payments
No origination fees, insurance, or taxes included
Payments are made at the end of each period

Tips

Longer terms lower the payment but increase total interest
Run multiple rates to see rate sensitivity
Add fees separately for a full cost view

Monthly Rate r = APR/12 and n = years * 12

Payment M = P * r * (1 + r)^n / ((1 + r)^n - 1)

Total Paid = M * n and Total Interest = Total Paid - Principal

Deferred Amount Due = P * (1 + r/c)^(c*years)

Bond Present Value = Face Value / (1 + r/c)^(c*years)

Usage examples

Copy a scenario, then tweak inputs to match your case.

Example

Car loan example

Inputs

Loan 25,000 at 6% APR
Term length 5 years

Outputs

Monthly payment about 483
Total interest about 4,000

Rounded values based on standard fixed payment math.

Example

Personal loan example

Inputs

Loan 8,000 at 11% APR
Term length 3 years

Outputs

Monthly payment about 262
Total interest about 1,400

Use the same inputs to compare multiple lenders.

Term vs interest (20,000 at 6%)

Term	Monthly payment	Total interest
3 years	608	1,900
5 years	387	3,200
7 years	292	4,500

Longer terms reduce payment but raise total interest.
